From a research perspective, OpenStreetMap is deservedly attracting a lot of attention from universities and similar institutions, and from academic scholars in 'geomatics', 'neogeography', 'volunteered geo-information' (VGI), 'digital cartography', 'participatory geoinformatics' etc. OpenStreetMap is fascinating and vast in terms of scale and variety of the data we offer, the technology we build, and uses we find for the data. But most of all, we are a fascinating and vast community. Whether you're interested in studying the community itself, or working with the datasets, we hope you'll become a part of it and share your knowledge, extend the map, improve existing technologies, and explore new horizons.

Introduction

To learn more about the project itself, the wiki offers a wealth of (sometimes a little disorganised) information. Get a quick overview at About. Dive into some technical details of current Development or if you prefer, take a look at some Books about OpenStreetMap. Resources for scientific processing and analysis of OSM data are reviewed at OSM Scientific Tools. An overview of OSM related reserch by Sukhjit Singh Sehra (Using Latent Semantic Analysis to Identify Research Trends in OpenStreetMap). A VGI Knowledge Portal was developed to collect research on the broader subject of volunteered geodata. Unfortunately, as of June 2021 it seems not available.

Greetings from our community

OpenStreetMap has a vibrant and open community, and we are happy about everyone who takes an interest in us.

There's no reason to study OSM from inside an ivory tower like you would study a colony of ants. You can come out and talk to us, tell us what you're up to, even discuss your methods or preliminary results, and you will generally have full cooperation from the community. As a community, we're sometimes a little sad if the first we hear of an academic project is when the paper is graded or published - maybe we could have offered some advice, or put you in touch with someone else who does similar work. At the conference SotM-EU 2011, Muki Haklay gave a talk with advice to academics interested in OSM and the video is available online.

An easy way to get involved in the community is to join the OSM science mailing list, where mappers interested in science and scientists interested in OSM meet.

Ideas for students

Main article: /Ideas

OpenStreetMap has several open problems which would make good student projects. These are items that need researching and "longer-term" issues which could be worked on by students as a project separate from the core open source development progress happening within the community. Further projects might be on the Google Summer of Code.

  For analysing, understanding and predicting the track/train-dynamics in order to develop comfortable and sustainable vehicles a sufficient description of the track course and conditions are key requirements. Not only the track irregularities but also the horizontal curvature affects the vehicle dynamics strongly. Nearly all cities owning light rail systems have gradually established the light rail traffic. By reasons of building density, road transportation infrastructure, and progress of the overall urban planning, the light rail infrastructure was constrained to the pre-existing environment. Thus, the track course is mainly optimized for efficient space use but not for best possible vehicle dynamics. To be able to analyse the track layout of tram networks at a bigger scale, an appropriate methodology that allows acquiring track course data is needed, which is the main objective of this paper. For this purpose, an open data approach was developed by the authors utilizing OpenStreetMap (OSM) to derive the horizontal track curvature based on geodata.

  The OpenStreetMap gained in importance in the recent years. Beside streets and places, there are also stored “POI” (Points of Interest). This information is available to anyone and has sufficient quality to be used for a tourism information system. By using a free and open source software a simple solution is created that allows even small areas of tourism to inform tourists about the amenities in their region on the web. A Web-GIS allows presenting the information online and in a spatial context.

  The disease transmitting mosquito Aedes Aegypti is an increasing global threat. It breeds in small artificial containers such as rainwater tanks and can be characterized by a short flight range. The resulting high spatial variability of abundance is challenging to model. Therefore, we tested an approach to map water tank density as a spatial proxy for urban Aedes Aegypti habitat suitability. Water tank density mapping was performed by a semi-supervised self-training approach based on open accessible satellite imagery for the city of Rio de Janeiro. We ran a negative binomial generalized linear regression model to evaluate the statistical significance of water tank density for modeling inner-urban Aedes Aegypti distribution measured by an entomological surveillance system between January 2019 and December 2021. Our proposed semi-supervised model outperformed a supervised model for water tank detection with respect to the F1-score by 22%. Water tank density was a significant predictor for the mean eggs per trap rate of Aedes Aegypti. This shows the potential of the proposed indicator to enrich urban entomological surveillance systems to plan more targeted vector control interventions, presumably leading to less infectious rates of dengue, Zika, and chikungunya in the future.
• "Assessing Completeness of OpenStreetMap Building Footprints Using MapSwipe" Ullah T, Lautenbach S, Herfort B, Reinmuth M, Schorlemmer D. - 2023-03-27 - https://doi.org/10.3390/ijgi12040143
  Natural hazards threaten millions of people all over the world. To address this risk, exposure and vulnerability models with high resolution data are essential. However, in many areas of the world, exposure models are rather coarse and are aggregated over large areas. Although OpenStreetMap (OSM) offers great potential to assess risk at a detailed building-by-building level, the completeness of OSM building footprints is still heterogeneous. We present an approach to close this gap by means of crowd-sourcing based on the mobile app MapSwipe, where volunteers swipe through satellite images of a region collecting user feedback on classification tasks. For our application, MapSwipe was extended by a completeness feature that allows to classify a tile as “no building”, “complete” or “incomplete”. To assess the quality of the produced data, the completeness feature was applied to four regions. The MapSwipe-based assessment was compared with an intrinsic approach to quantify completeness and with the prediction of an existing model. Our results show that the crowd-sourced approach yields a reasonable classification performance of the completeness of OSM building footprints. Results showed that the MapSwipe-based assessment produced consistent estimates for the case study regions while the other two approaches showed a higher variability. Our study also revealed that volunteers tend to classify nearly completely mapped tiles as “complete”, especially in areas with a high OSM building density. Another factor that influenced the classification performance was the level of alignment of the OSM layer with the satellite imagery.
• "Private Vehicles Greenhouse Gas Emission Estimation at Street Level for Berlin Based on Open Data" Ulrich V, Brückner J, Schultz M, Vardag SN, Ludwig C, Fürle J, Zia M, Lautenbach S, Zipf A. - 2023-03-24 - https://doi.org/10.3390/ijgi12040138
  As one of the major greenhouse gas (GHG) emitters that has not seen significant emission reductions in the previous decades, the transportation sector requires special attention from policymakers. Policy decisions, thereby need to be supported by traffic emission assessments. Estimations of traffic emissions often rely on huge amounts of actual traffic data whose availability is limited, hampering the transferability of the estimation approaches in time and space. Here, we propose a high-resolution estimation of traffic emissions, which is based entirely on open data, such as the road network and points of interest derived from OpenStreetMap (OSM). We estimated the annual average daily GHG emissions from individual motor traffic for the OSM road network in Berlin by combining the estimated Annual Average Daily Traffic Volume (AADTV) with respective emission factors. The AADTV was calculated by simulating car trips with the open routing engine Openrouteservice, weighted by activity functions based on statistics of the German Mobility Panel. Our estimated total annual GHG emissions were 7.3 million t CO2 equivalent. The highest emissions were estimated for the motorways and major roads connecting the city center with the outskirts. The application of the approach to Berlin showed that the method could reflect the traffic pattern. As the input data is freely available, the approach can be applied to other study areas within Germany with little additional effort.

  The COVID-19 pandemic strongly impacted people's daily lives. However, it remains unknown how the pandemic situation affects daily-life experiences of individuals with preexisting severe mental illnesses (SMI). In this real-life longitudinal study, the acute onset of the COVID-19 pandemic in Germany did not cause the already low everyday well-being of patients with schizophrenia (SZ) or major depression (MDD) to decrease further. On the contrary, healthy participants’ well-being, anxiety, social isolation, and mobility worsened, especially in healthy individuals at risk for mental disorder, but remained above the levels seen in patients. Despite being stressful for healthy individuals at risk for mental disorder, the COVID-19 pandemic had little additional influence on daily-life well-being in psychiatric patients with SMI. This highlights the need for preventive action and targeted support of this vulnerable population.

  The continuing growth of settlement and traffic areas in the dynamic urban regions continues to take place primarily at the expense of agricultural areas. In the BMBF funded project NACHWUCHS, the possibilities for a change of perspective and paradigm in development are being investigated for the metropolis of Cologne and its surrounding area on the left bank of the Rhine. The focus is on alternative scenarios for sustainable, land-efficient and climate-sensitive land use with special consideration of agricultural land and its diverse strategic significance and functions. For this purpose, the new land use model NACHWUCHS is used to model the development of settlement areas in the cities and municipalities of the region. Using different scenarios, potential development paths for the entire region are shown, analyzed and evaluated with a consistent indicator system from the areas of housing, agriculture as well as landscape ecology on the basis of raster-based spatial data. The approach thus provides valid bases for land use decisions on different spatial and temporal scales.

Based on 12-year time series of seven OSM data contribution activities extracted from 20 large cities worldwide, we investigate the temporal dynamic of OSM data production, more specifically, the auto- and cross-correlation, temporal trend, and annual seasonality of these activities. Furthermore, we evaluate and compare nine different temporal regression methods for forecasting such activities in horizons of 1–4 weeks. Several insights could be obtained from our analyses, including that the contribution activities tend to grown linearly in a moderate intra-annual cycle. Also, the performance of the temporal forecasting methods shows that they yield in general more accurate estimations of future contribution activities than a baseline metric, i.e. the arithmetic average of recent previous observations. In particular, the well-known ARIMA and the exponentially weighted moving average methods have shown the best performances.
• "A text and image analysis workflow using citizen science data to extract relevant social media records: Combining red kite observations from Flickr, eBird and iNaturalist" Hartmann, M.C., Schott, M., Dsouza, A., Metz, Y., Volpi, M., Purves, R. - 2022-09-06 - https://doi.org/10.1016/j.ecoinf.2022.101782
  There is an urgent need to develop new methods to monitor the state of the environment. One potential approach is to use new data sources, such as User-Generated Content, to augment existing approaches. However, to date, studies typically focus on a single date source and modality. We take a new approach, using citizen science records recording sightings of red kites (Milvus milvus) to train and validate a Convolutional Neural Network (CNN) capable of identifying images containing red kites. This CNN is integrated in a sequential workflow which also uses an off-the-shelf bird classifier and text metadata to retrieve observations of red kites in the Chilterns, England. Our workflow reduces an initial set of more than 600,000 images to just 3065 candidate images. Manual inspection of these images shows that our approach has a precision of 0.658. A workflow using only text identifies 14% less images than that including image content analysis, and by combining image and text classifiers we achieve almost perfect precision of 0.992. Images retrieved from social media records complement those recorded by citizen scientists spatially and temporally, and our workflow is sufficiently generic that it can easily be transferred to other species.
• "Improving OpenStreetMap missing building detection using few-shot transfer learning in sub-Saharan Africa" Li, H., Herfort, B., Lautenbach, S., Chen, J., Zipf, A. - 2022-05-04 - https://doi.org/10.1111/tgis.12941
  OpenStreetMap (OSM) has been intensively used to support humanitarian aid activities, especially in the Global South. Its data availability in the Global South has been greatly improved via recent humanitarian mapping campaigns. However, large rural areas are still incompletely mapped. The timely provision of map data is often essential for the work of humanitarian actors in the case of disaster preparation or disaster response. Therefore, it has become a vital challenge to boost the speed and efficiency of existing humanitarian mapping workflows. We address this challenge by proposing a novel few-shot transfer learning (FSTL) method to improve the accuracy of OSM missing building detection. We trained two popular object detection models (i.e., Faster R-CNN and SSD) in a training area in Tanzania and transferred the model to target areas in Cameroon and Mozambique. The FSTL method significantly improved the base model performance even with only one training shot. Moreover, we successfully produced a grid-based OSM missing building map (DeepVGI) of 10 m spatial resolution with over 96% overall accuracy (ACC) and 0.85 Matthews correlation coefficient (MCC) in both Cameroon and Mozambique. Such maps show great potential to assess and estimate the overall completeness of OSM buildings to support humanitarian mapping activities, especially in places where other (e.g., buildings, roads) datasets are not available.
• "Assessing road criticality and loss of healthcare accessibility during floods: the case of Cyclone Idai, Mozambique 2019" Petricola, S., Reinmuth, M., Lautenbach, S., Hatfiel, C., Zipf, A. - 2022 - https://doi.org/10.1186/s12942-022-00315-2
  The ability of disaster response, preparedness, and mitigation efforts to assess the loss of physical accessibility to health facilities and to identify impacted populations is key in reducing the humanitarian consequences of disasters. Recent studies use either network- or raster-based approaches to measure accessibility in respect to travel time. Our analysis compares a raster- and a network- based approach that both build on open data with respect to their ability to assess the loss of accessibility due to a severe flood event. As our analysis uses open access data, the approach should be transferable to other flood-prone sites to support decision-makers in the preparation of disaster mitigation and preparedness plans.
• "SocialMedia2Traffic: Derivation of Traffic Information from Social Media Data" Zia, M.; Fürle, J.; Ludwig, C.; Lautenbach, S.; Gumbrich, S.; Zipf, A. - 2022-09-13 - https://doi.org/10.3390/ijgi11090482
  Traffic prediction is a topic of increasing importance for research and applications in the domain of routing and navigation. Unfortunately, open data are rarely available for this purpose. To overcome this, the authors explored the possibility of using geo-tagged social media data (Twitter), land-use and land-cover point of interest data (from OpenStreetMap) and an adapted betweenness centrality measure as feature spaces to predict the traffic congestion of eleven world cities. The presented framework and workflow are termed as SocialMedia2Traffic. Traffic congestion was predicted at four tile spatial resolutions and compared with Uber Movement data. The overall precision of the forecast for highly traffic-congested regions was approximately 81%. Different data processing steps including ways to aggregate data points, different proxies and machine learning approaches were compared. The lack of a universal definition on a global scale to classify road segments by speed bins into different traffic congestion classes has been identified to be a major limitation of the transferability of the framework. Overall, SocialMedia2Traffic further improves the usability of the tested feature space for traffic prediction. A further benefit is the agnostic nature of the social media platform’s approach.
• "Sugarcane abandonment mapping in Rio de Janeiro state Brazil" de Castro, P.I.B., Yin, H., Teixera Junior, P.D., Lacerda, E., Pedroso, R., Lautenbach, S., Vicens, R.S. - 2022-07-28 - https://doi.org/10.1016/j.rse.2022.113194
  The mapping of sugarcane plantations and their changes is relevant to the economy and the environment, notably due to sugarcane's interface in the biofuel industry through ethanol. The necessary mapping of sugarcane crop changes is especially challenging when plantation occurs under smallholders' land ownership structures used for heterogeneous crop management. We evaluated two approaches to address this challenge with the example of sugarcane abandonment in the Norte Fluminense Region, Northeastern Rio de Janeiro state, Brazil. The region is characterized by a large share of smallholders. We trained a random forest classifier for sugarcane for 2018 based on all available Landsat imagery. Based on the concept of temporal generalization, we applied the classifier trained in 2018 for the period from 1986 until 2020. The resulting annual sugarcane probability maps were used as input for two abandonment mapping methods: LandtrendR and muti-temporal cropland abandonment mapping. The performance of both approaches was evaluated based on a stratified sampling approach. We detected three distinct trajectories for sugarcane farmland: i) permanently abandoned sugarcane, ii) fallow sugarcane, and iii) and stable sugarcane. The multi-temporal cropland abandonment mapping performed better for the sugarcane abandonment class (F1 = 0.84) than the LandtrendR approach (F1 = 0.21). The LandtrendR results revealed a higher omission (PA = 0.12) in mapping the sugarcane abandonment class. For the multi-temporal cropland abandonment mapping, we found that 66% (67,353 ha) of the stable sugarcane areas were abandoned between 1990 and 2016. The highest abandonment rates occurred between 1990 and 1994 and between 2010 and 2016. The spatial distribution of abandonment was heterogeneous. The earliest abandonment was concentrated in the northern part of the study area. The most recent abandonment was more extensive in the southern part of the study site. Our results highlight the advantages and challenges of using Landsat time series to map sugarcane abandonment in a heterogeneous management system. Our results also highlight the spatially and temporal heterogeneous pattern of sugarcane abandonment in the region and provide the necessary database for subsequent studies to identify underlying and proximate causes for the abandonment.

  The study aims to identify the gaps and the potentialities of citizen-generated data in four axes of warning system: (1) risk knowledge, (2) flood forecasting and monitoring, (3) risk communication and (4) flood risk governance.
• "Understanding spatiotemporal trip purposes of urban micro-mobility from the lens of dockless e-scooter sharing" Li, H., Yuan, Z., Novack, T., Huang, W., Zipf, A. - 2022-06-20 - https://doi.org/10.1016/j.compenvurbsys.2022.101848
  Over the last two years, we have witnessed the ever-fast growth of micro-mobility services (e.g., e-bikes and e-scooters), which brings both challenges and innovations to the traditional urban transportation systems. For example, they provide an opportunity to better address the “last mile” problem due to their convenience, flexibility and zero emission. As such, it is essential to understand why and how urban dwellers use these micro-mobility services across space and time. In this paper, we aim to understand spatiotemporal trip purposes of urban micro-mobility through the lens of dockless e-scooter user behavior. We first develop a spatiotemporal topic modeling method to infer the underlying trip purpose of dockless e-scooter usage. Then, using Washington, D.C. as a case study, we apply the model to a dataset including 83,002 valid user trips together with 19,370 POI venues and land use land cover data to systematically explore the trip purposes of micro-mobility across space and time in the city. The results confirm a set of uncovered 100 Trips Topics as an informative and effective proxy of the spatiotemporal trip purposes of micro-mobility users. The findings in this paper provide important insights for city authorities and dockless e-scooter companies into more sustainable urban transportation planning and more efficient vehicle fleet reallocation in future smart cities.
• "Leveraging OpenStreetMap and Multimodal Remote Sensing Data with Joint Deep Learning for Wastewater Treatment Plants Detection" Li, H., Zech, J., Hong, D., Ghamisi, P., Schultz, M., Zipf, A. - 2022-05-15 - https://doi.org/10.1016/j.jag.2022.102804
  Humans rely on clean water for their health, well-being, and various socio-economic activities. During the past few years, the COVID-19 pandemic has been a constant reminder of about the importance of hygiene and sanitation for public health. The most common approach to securing clean water supplies for this purpose is via wastewater treatment. To date, an effective method of detecting wastewater treatment plants (WWTP) accurately and automatically via remote sensing is unavailable. In this paper, we provide a solution to this task by proposing a novel joint deep learning (JDL) method that consists of a fine-tuned object detection network and a multi-task residual attention network (RAN). By leveraging OpenStreetMap (OSM) and multimodal remote sensing (RS) data, our JDL method is able to simultaneously tackle two different tasks: land use land cover (LULC) and WWTP classification. Moreover, JDL exploits the complementary effects between these tasks for a performance gain. We train JDL using 4,187 WWTP features and 4,200 LULC samples and validate the performance of the proposed method over a selected area around Stuttgart with 723 WWTP features and 1,200 LULC samples to generate an LULC classification map and a WWTP detection map. Extensive experiments conducted with different comparative methods demonstrate the effectiveness and efficiency of our JDL method in automatic WWTP detection in comparison with single-modality/single-task or traditional survey methods. Moreover, lessons learned pave the way for future works to simultaneously and effectively address multiple large-scale mapping tasks (e.g., both mapping LULC and detecting WWTP) from multimodal RS data via deep learning.
• "Der Zusammenhang zwischen Stress und körperlicher Aktivität: Mind the ecological fallacy" (The association of stress and physical activity: Mind the ecological fallacy) Reichert, M., Brüßler, S., Reinhard, I. et al. - 2022-05-06 - https://doi.org/10.1007/s12662-022-00823-0
  Psychological stress and physical activity are interrelated, constituting a relevant association to human health, especially in children. However, the association’s nature remains elusive, i.e., why psychological stress predicts both decreased and increased physical activity. To test whether effects vary as a function of the level of analyses, we derived intensive longitudinal data via accelerometers and stress questionnaires from 74 children across 7 days as they went about their daily routines (n = 513 assessments). Multilevel modelling analyses revealed that between children, higher psychological stress predicted decreased physical activity (standardized beta coefficient = −0.14; p = 0.046). Concurrently, within those children, higher psychological stress predicted increased physical activity across days (standardized beta coefficient = 0.09; p = 0.015). Translated to practice, children who experienced more stress than others moved less, but children were more active on days when they experienced heightened stress. This suggests that the analyses level is crucial to the understanding of the association between psychological stress and physical activity and should be considered to receive unequivocal results. If replicated, e.g., including high-frequency sampling and experimental manipulation in everyday life for in-depth insights on underlying mechanisms and causality, our findings may be translated to individually tailored (digital) prevention and intervention strategies which target children’s distress-feelings despite impairing their heightened physical activity in stressful situations and identify tipping points of chronic stress phases. Therefore, we especially call for more intensive longitudinal data approaches to tackle thus far neglected within-subject issues in the field of physical activity, sport and exercise research.

• "Greenwashing in the US metal industry? A novel approach combining SO2 concentrations from satellite data, a plant-level firm database and web text mining" Schmidt, S,, Kinne, J., Lautenbach, S., Blaschke, T., Lenz, D., Resch, B. - 2022-04-27 - https://doi.org/10.1016/j.scitotenv.2022.155512
  This study deals with the issue of greenwashing, i.e. the false portrayal of companies as environmentally friendly. The analysis focuses on the US metal industry, which is a major emission source of sulfur dioxide (SO2), one of the most harmful air pollutants. One way to monitor the distribution of atmospheric SO2 concentrations is through satellite data from the Sentinel-5P programme, which represents a major advance due to its unprecedented spatial resolution. In this paper, Sentinel-5P remote sensing data was combined with a plant-level firm database to investigate the relationship between the US metal industry and SO2 concentrations using a spatial regression analysis. Additionally, this study considered web text data, classifying companies based on their websites in order to depict their self-portrayal on the topic of sustainability. In doing so, we investigated the topic of greenwashing, i.e. whether or not a positive self-portrayal regarding sustainability is related to lower local SO2 concentrations. Our results indicated a general, positive correlation between the number of employees in the metal industry and local SO2 concentrations. The web-based analysis showed that only 8% of companies in the metal industry could be classified as engaged in sustainability based on their websites. The regression analyses indicated that these self-reported ”sustainable” companies had a weaker effect on local SO2 concentrations compared to their “non-sustainable” counterparts, which we interpreted as an indication of the absence of general greenwashing in the US metal industry. However, the large share of firms without a website and lack of specificity of the text classification model were limitations to our methodology.
• "Zooming-in for climate action—hyperlocal greenhouse gas data for mitigation action?" M. Jungmann, S. N. Vardag, F. Kutzner, F. Keppler, M. Schmidt, N. Aeschbach, U. Gerhard, A. Zipf, S. Lautenbach, A. Siegmund, T. Goeschl & A. Butz - 2022-04-08 - https://doi.org/10.1007/s44168-022-00007-4
  While the international community has made progress in adopting goals and agreements in the field of climate change mitigation, efforts to reduce greenhouse gas (GHG) emissions are significantly lacking behind global ambitions for acceptable climate change. In this perspective, we discuss whether a window of opportunity for more effective climate action is emerging due to the convergence of new scientific and technological opportunities to provide high-resolution information on GHG emissions and emerging polycentric governance forms. We hypothesize that scientific and technological developments in the geophysical sciences and geoinformatics could provide the information policy makers need to put in place effective policies on climate change mitigation and to have measures to verify the effectiveness of their mitigation policies. To contribute to a better understanding of these developments and the requirements for effective climate action, new forms of inter- and transdisciplinary research become urgently necessary.
• "Using crowdsourced images to study selected cultural ecosystem services and their relationships with species richness and carbon sequestration" H. Lee, B. Seo, A. F. Cord, M. Volk, S. Lautenbach - 2022-02-08 - https://doi.org/10.1016/j.ecoser.2022.101411
  Due to the difficulty of capturing spatially explicit information on cultural ecosystem services (CES), previous studies have paid less attention to their relationships with other services. In this study, we quantified the relationships between selected CES using crowdsourced photographs, carbon storage and species richness of plants and butterflies for a case study in Saxony, Germany. The relationships were quantified based on the mutual information metric and using principal component analysis. We further conducted a regression analysis to control for environmental and infrastructure factors such as the share of land use classes, landscape diversity and the presence of viewpoints and picnic sites. Our results showed overall positive relationships between CES indicators and carbon sequestration as well as species richness. However, the magnitude of the relationships varied: the CES indicators showed a stronger relationship with butterfly species richness than with plant species richness. Both CES indicators showed the strongest positive relationship with carbon sequestration. This positive relationship was likely driven by forest cover, which was strongly associated with carbon storage. However, our regression analysis also showed that too much forest cover reduces the perceived CES, in particular for landscape aesthetics. Our findings provide additional information for spatial planning in the study region.
• "Automatic mapping of national surface water with OpenStreetMap and Sentinel-2 MSI data using deep learning" Li, H. J. Zech, C. Ludwig, S. Fendrich, A. Shapiro, M. Schultz, A. Zipf - 2021-10-19 - https://doi.org/10.1016/j.jag.2021.102571
  Large-scale mapping activities can benefit from the vastly increasing availability of earth observation (EO) data, especially when combined with volunteered geographical information (VGI) using machine learning (ML). High-resolution maps of inland surface water bodies are important for water supply and natural disaster mitigation as well as for monitoring, managing, and preserving landscapes and ecosystems. In this paper, we propose an automatic surface water mapping workflow by training a deep residual neural network (ResNet) based on OpenStreetMap (OSM) data and Sentinel-2 multispectral data, where the Simple Non-Iterative Clustering (SNIC) superpixel algorithm was employed for generating object-based training samples. As a case study, we produced an open surface water layer for Germany using a national ResNet model at a 10 m spatial resolution, which was then harmonized with OSM data for final surface water products. Moreover, we evaluated the mapping accuracy of our open water products via conducting expert validation campaigns, and comparing to existing water products, namely the WasserBLIcK and Global Surface Water Layer (GSWL). Using 4,600 validation samples in Germany, the proposed model (ResNet+SNIC) achieved an overall accuracy of 86.32% and competitive detection rates over the WasserBLIcK (87.47%) and GSWL (98.61%). This study provides comprehensive insights into how to best explore the synergy of VGI and ML of EO data in a large-scale surface water mapping task.
• "Analysing the Impact of Large Data Imports in OpenStreetMap" Witt, R.; Loos, L.; Zipf, A. - 2021-08-06 - https://doi.org/10.3390/ijgi10080528
  OpenStreetMap (OSM) is a global mapping project which generates free geographical information through a community of volunteers. OSM is used in a variety of applications and for research purposes. However, it is also possible to import external data sets to OpenStreetMap. The opinions about these data imports are divergent among researchers and contributors, and the subject is constantly discussed. The question of whether importing data, especially large quantities, is adding value to OSM or compromising the progress of the project needs to be investigated more deeply. For this study, OSM’s historical data were used to compute metrics about the developments of the contributors and OSM data during large data imports which were for the Netherlands and India. Additionally, one time period per study area during which there was no large data import was investigated to compare results. For making statements about the impacts of large data imports in OSM, the metrics were analysed using different techniques (cross-correlation and changepoint detection). It was found that the contributor activity increased during large data imports. Additionally, contributors who were already active before a large import were more likely to contribute to OSM after said import than contributors who made their first contributions during the large data import. The results show the difficulty of interpreting a heterogeneous data source, such as OSM, and the complexity of the project. Limitations and challenges which were encountered are explained, and future directions for continuing in this field of research are given.
• "Entwicklung eines Regressionsmodells für die Vollständigkeitsanalyse des globalen OpenStreetMap-Datenbestands an Nahverkehrs-Busstrecken" (Development of a Regression Model for the Analysis of Local Bus Route Data Completeness on OpenStreetMap) Oliver Fritz, Michael Auer, Alexander Zipf - 2021-07 - https://doi.org/10.14627/537707025
  The quality of geodata on OpenStreetMap (OSM) is characterized by heterogeneity. Results of conventional approaches of quality assessment based on the comparison with reference data can thus not be applied to the entire dataset. Hence, the completeness of OSM data is usually analysed using intrinsic methods. Here, we propose a novel approach that consists in the generation of reference data via a regression model. Using demographic and socio-economic raster datasets and sporadically available GTFS data, the number of local bus routes is predicted on the cells of a global hexagon grid. The results are compared with the OSM dataset.

  This article investigates the role of digital technologies and data innovations, such as big data and citizen-generated data, to enable transformations to sustainability. We reviewed recent literature in this area and identified that the most prevailing assumption of work is related to the capacity of data to inform decision-making and support transformations. However, there is a lack of critical investigation on the concrete pathways for this to happen. We present a framework that identifies scales and potential pathways on how data generation, circulation and usage can enable transformations to sustainability. This framework expands the perspective on the role and functions of data, and it is used to outline a critical research agenda for future work that fully considers the socio-cultural contexts and practices through which data may effectively support transformative pathways to sustainable development.
• "Influence of Spatial and Temporal Resolution on Time Series-Based Coastal Surface Change Analysis using Hourly Terrestrial Laser Scans" K. Anders, L. Winiwarter, H. Mara, R. C. Lindenbergh, S. E. Vos, B. Höfle - 2021-06-17 - https://doi.org/10.5194/isprs-annals-V-2-2021-137-2021
  Near-continuously acquired terrestrial laser scanning (TLS) data contains valuable information on natural surface dynamics. An important step in geographic analyses is to detect different types of changes that can be observed in a scene. For this, spatiotemporal segmentation is a time series-based method of surface change analysis that removes the need to select analysis periods, providing so-called 4D objects-by-change (4D-OBCs). This involves higher computational effort than pairwise change detection, and efforts scale with (i) the temporal density of input data and (ii) the (variable) spatial extent of delineated changes. These two factors determine the cost and number of Dynamic Time Warping distance calculations to be performed for deriving the metric of time series similarity. We investigate how a reduction of the spatial and temporal resolution of input data influences the delineation of twelve erosion and accumulation forms, using an hourly five-month TLS time series of a sandy beach. We compare the spatial extent of 4D-OBCs obtained at reduced spatial (1.0 m to 15.0 m with 0.5 m steps) and temporal (2 h to 96 h with 2 h steps) resolution to the result from highest-resolution data. Many change delineations achieve acceptable performance with ranges of ±10 % to ±100 % in delineated object area, depending on the spatial extent of the respective change form. We suggest a locally adaptive approach to identify poor performance at certain resolution levels for the integration in a hierarchical approach. Consequently, the spatial delineation could be performed at high accuracy for specific target changes in a second iteration. This will allow more efficient 3D change analysis towards near-realtime, online TLS-based observation of natural surface changes.
• "The Impact of Community Happenings in OpenStreetMap — Establishing a Framework for Online Community Member Activity Analyses" Schott, M, Grinberger, A.Y., Lautenbach, S. & Zipf, A. - 2021-03-14 - https://doi.org/10.3390/ijgi10030164
  The collaborative nature of activities in Web 2.0 projects leads to the formation of online communities. To reinforce this community, these projects often rely on happenings centred around data creation and curation activities. We suggest an integrated framework to directly assess online community member performance in a quantitative manner and applied it to the case study of OpenStreetMap. A set of mappers who participated in both field and remote mapping-related happenings was identified. To measure the effects of happenings, we computed attributes characterising the mappers’ contribution behaviour before and after the happenings and tested for significant impacts in relation to a control group. Results showed that newcomers to OpenStreetMap adopted a contribution behaviour similar to the contribution behaviour typical for the respective happening they attended: When contributing after the happening, newcomers who attended a remote mapping event tended to concentrate on creating new data with lower quality but high quantity in places foreign to their home region; newcomers who attended a field mapping event updated and enhanced existing local data with high accuracy. The behaviour of advanced mappers stayed largely unaffected by happenings. Unfortunately, our results did not reveal a positive effect on the community integration of newcomers through happenings.
• "An analysis of the spatial and temporal distribution of large‐scale data production events in OpenStreetMap" Grinberger, A.Y., Schott, M., Raifer, M. & Zipf, A. - 2021-03-19 - https://doi.org/10.1111/tgis.12746
  Organized mapping activities within OpenStreetMap frequently lead to the production of massive amounts of data over a short period. In this article we utilize a novel procedure to identify such large‐scale data production events in the history of OpenStreetMap and analyze their patterns. We find that events account for a significant share of OpenStreetMap data and that organizational practices have shifted over time towards local knowledge‐based events and well‐organized data imports. However, regions in the “Global South” remain dependent on remote mapping events, pointing to uneven geographies of representation. We also find that events are frequently followed by periods of increased activity, with the exact nature of effects depending on contextual elements such as previous events. These findings portray organized activities as a significant and unique component which requires consideration when using OpenStreetMap data and analyzing their quality.

  Over the last couple of years, the growingOpenStreetMap(OSM) database repeatedly proved its potential for varioususe cases, including disaster management. Disaster mapping activations show increasing numbers of contributions,but oftentimes raise questions related to the quality of the providedVolunteered Geographic Information. In orderto better monitor and understand OSM mapping and data quality, we developed theohsomesoftware platform thatapplies big data technology to OSM full history data. OSM full history data monitoring allows detailed analysesof the OSM data evolution and the detection of remarkable patterns over time. This paper illustrates the specificpotential of our platform for disaster activations by means of two case studies. Initial results demonstrate thatour flexible and scalable platform structure enables fast and easy information extraction and supports mappingprocesses and data quality assurance.

  The free OpenStreetMap database contains valuable data for 3D rendering, but elevation needs to be extracted from an external source such as NASA's SRTM raster data. Among several possible algorithms for approximating a terrain surface, natural neighbor interpolation and especially piecewise approximation using least squares yield good experimental results. A proposed framework of connectors and constraints may serve to further refine the terrain surface by inserting information from OpenStreetMap's vector data. Linear programming can be applied to the problem of performing this refinement. A prototype implementation based on the open-source 3D renderer OSM2World produces examples for advantages and disadvantages of that approach.

  Web technologies provide the basis to distribute digital information worldwide and in realtime but they have also established the Web as a ubiquitous application platform. The Web evolved from simple text data to include advanced layout, images, audio, and recently streaming video. Today, as our digital environment becomes increasingly three-dimensional (e.g. 3D cinema, 3D video, consumer 3D displays, and high-performance 3D processing even in mobile devices) it becomes obvious that we must extend the core Web technologies to support interactive 3D content. Instead of adapting existing graphics technologies to the Web, XML3D uses a more radical approach: We take today’s Web technology and try to find the minimum set of additions that fully support interactive 3D content as an integral part of mixed 2D/3DWeb documents. XML3D enables portable cross-platform authoring, distribution, and rendering of and interaction with 3D data. As a declarative approach XML3D fully leverages existing web technologies including HTML, Cascading Style Sheets (CSS), the Document Object Model (DOM), and AJAX for dynamic content. All 3D content is exposed in the DOM, fully supporting DOM scripting and events, thus allowing Web designers to easily apply their existing skills. The design of XML3D is based on modern programmable graphics hardware, e.g. supports efficient mapping to GPUs without maintaining copies. It also leverages a new approach to specify shaders independently of specific rendering techniques or graphics APIs. We demonstrated the feasibility of our approach by integrating XML3D support into two major open browser frameworks from Mozilla and WebKit as well as providing a portable implementation based on JavaScript and WebGL.
• "XML3D Physics: Declarative Physics Simulation for the Web" - Kristian Sons and Philipp Slusallek - 2011, [138]
  As interactive 3D graphics has become an integral part of modern Web browsers via the low-level WebGL API, it now becomes apparent that higher-level declarative approaches integrated with HTML5 are needed in order to make 3D graphics broadly and easily accessible to Web developers. A key component of interactive 3D scenes are physics simulations. However, specifying the physics properties required major changes to the scene graph in the past. In this paper, we present a declarative and orthogonal physics annotation framework that nicely separates the generic 3D scene description from its physics properties. The approach is based on the declarative XML3D format as an extension to HTML5, has been implemented as a plug-in that runs in three browsers that support XML3D and is demonstrated with a number of examples and performance evaluations.

  The objective of our project is to provide OpenStreetMap (OSM) data using SUAS MapServer. ut the level of feature classes is not sufficient enough for us because we expect of deriving more feature classes in detail. In order to solve the problem, we found a way to separate the feature classes into more detailed feature classes firstly, and then import new shape format files into SUAS MapServer for visualization of OSM data.

• "Simulation von Fahrzeugbewegungen II"
  The aim is to create a simulation of car movements on the Open Street Map.
  In order to achieve a realistic simulation (as possible) all cars possess individual properties influencing the behaviour of accelerating, braking and the detection of other moving actors. Using a modified version of Osmosis, the application is able to read Open Street Map XML files, writing them into a MySQL database and finally optimizing the data structure of this database for improved and faster calculating of road junctions and parsing of the map. Actually all moving vehicles are driving, Open Street Map is being read, parsed and used as the fundament of the simulation. The detection of road junction and collision is still in development, but in a quite advanced state.
  All actors already do have certain properties for braking, accelerating and their final speed. The final goal of the project is to link other Systems with this simulation of abstract moving vehicles. Adding the ability of influence to each linked system, a complex system is created out of various abstract systems making empirical research and applications with today's computers possible.

• "BizkaiSense" "(BizkaiSense)" - A. Pijoan, I. Oribe-Garcia, G. Sorrosal and C.E. Borges - 2013
  BizkaiSense is an intelligent sensory Infrastructure for Improvement of the Sustainability, financed by Diputación Foral de Bizkaia through Bizkailab program. Its goal is to collect environment variables data, through the deployment of sensors in order to enable to take strategical decision related to sustainability. It aims to integrate environmental indicators calculation, improve it and make all that information accessible for the citizens. Some of the main indicators are "Citizens with access by foot to green areas" (Indicator 2), "Local air quality" (Indicator 3), "Citizens exposed to high noise levels" (Indicator 6), "Sustainable land use" (Indicator 7), "Villages with accessibility plan" (Indicator 23)... The necessary data is taken from OpenStreetMap Overpass API and GeoEuskadi, the Harmonized Topographic Database of the Basque Government.

• "SAILEA: Sistema Automático de Inspección de Líneas Eléctricas Aéreas" "(SAILEA: Overhead Power Line Automatic Inspection System)" - G. Sorrosal and M. González - 2013
  The inspection of overhead power lines plays an essential factor in maintaining an electricity transmission. Surveillance and maintenance of electrical infrastructures is the key to ensuring and improving the quality of service. An inspection system can prevent and predict future damages. Within this project, an automatic overhead power line inspection system by UAV (Unmanned Aerial Vehicle) has been developed. The UAV flies along the power lines gathering images and data, which are processed by different computer vision algorithms to obtain the inspection reports. The inspection system must have outstanding information about the key elements for the inspection of the power lines defined in the legislation, such as electric pylons, buildings, roads, railroads, power line crossings or vegetation. The objective is to obtain the coordinates and characteristic distances of these elements to the power lines. The necessary cartographic data have been obtained from OpenStreetMap and GeoEuskadi, the Harmonized Topographic Database of the Basque Government.

• "Long Term Load Forecasting" "(Long Term Load Forecasting)" - C.E. Borges, Y.K. Penya, I. Fernández, O. Kamara and A. Pijoan - 2013
  Long-term load forecasting aims at predicting the evolution of the energy consumption in a certain area. The study of load forecasting can be divided into two areas in relation to the type of demand growth: vertical growth (related to the increment in the electric consumption of already existing customers) or horizontal growth (related to the appearance of new customers on a certain location). Focusing on the horizontal growth, the objective of the system developed is to forecast the apparition of new electrical clients and estimate their future demand within a certain area in the next 5 to 10 years. The agent system needs information regarding the location, layout and type of infrastructures, which is obtained from OpenStreetMap and the public cadastre (Cat2Osm2). With these inputs, the system predicts and provides a geospatial view of the city growth in terms of both number of customers and energy needs. This approach would let the utility manager analyze whether the grid needs to be upgraded in order to give a reliable response to future energy needs.

  As businesses and governments integrate OpenStreetMap (OSM) into their services in ways that require comprehensive coverage, there is a need to expand research outside of major urban areas and consider the strength of the map in smaller cities. A place-specific inquiry into the OSM contributor sets in small cities allows an intimate look at user motives, locations, and editing habits that are readily described in the OSM metadata and user profile pages.

• "What motivates OpenStreetMap users?" "(Small-scale crisis response mapping: comparing user contributions to events in OpenStreetMap)" - Erika Kamptner, Fritz C. Kessler - 2018, [233]
  Analysis determined whether there was an increase in OSM contributions in the immediate aftermath of an incident and characterized these contributors as serious or casual mappers, local to or remote from the incident, and what kinds of features or attributes are being updated. Results from this research showed an increase in user contributions for most incidents in the 30 days after the incident, with 41–98% of contributions occurring in the first 10 days after an event for some study areas. Based on each contributor editing history, most contributors were classified as being serious, remote mappers. This research contributes to a growing body of evidence that investigates potential motivation factors for contributions to OSM.

University of Maryland:

• "TerpNav" - Faster Team
  A OSM based highly detailed OSM map
  TerpNav is a pedestrian map of the University of Maryland at College Park (Go Terps) and is built on the OSM base. A successful student project, it was adopted as the official campus pedestrian map several years ago, and today sees heavy use by campus residents and visitors alike. Heaviest use is in the first days of class each semester as students hunt for the best paths to find their classes! One of the important and driving features of TerpNav is its support for handicap accessibility, and an option is to present best paths based on absence of stairs and availability of curb cuts.
  The latest version of TerpNav is TN3 which evidences our experiences with usage patterns and provides better searching capabilities. The work continues in support of social networking capabilities that naturally hang on a geo-aware tool like TerpNav.

• "Tropes 2.0: Mobilization in OpenStreetMap" - Josef Eckert
  You can now access the completed thesis here: "Tropes 2.0: Strategic Mobilizations of the Geoweb"
  Completed a 2 years master's thesis at the University of Washington, Seattle. Explores how social movement theory may offer a component of the answer to why people choose to contribute data to the OpenStreetMap project. Blending ethnographic tools of participant observation and semi-structured interviews, Joe seeks a more nuanced explanation of participant motivation. He identifies 3 tropes: "you", "the community", and "the map" that are unpacked as mobilizing frameworks and situated understandings on the part of user-participants. Josef's influences include his own past work in public participatory GIS for underrepresented demographics, as well as feminist critiques of science and technology studies, critical GIS, socio-legal studies, and geopolitics. He continues working with OpenStreetMap data in his Ph. D. work that hopes to examine the means by which some data are privileged for collection over others, and how this might be leveraged to correct data with poor accuracy.
