Data Quality
All contributions through HOT's Tasking Manager are tracked with a unique changeset comment tag: #PNGearthquakeMarch2024
Validation
Validation permissions for the Tasking Manager projects are restricted to users with intermediate or advanced level.
For Mappers
How You Can Contribute
MapSwipe
Given the large affected area and low population densities of Papua New Guinea the GDACS event summary Rapid Impact Intensity area was used to generate a series of MapSwipe projects to locate built up areas (buildings). Check on the status of these projects here:
The MapSwipe project outputs are being used to generate HOT Tasking Manager projects to map buildings. Separate Tasking Manager projects will be set up to map roads.
Learn to Map
- Most of our volunteer needs are for remote OSM contributors, visit LearnOSM.org to get started.
Mapping Priority
- Please choose from highest priority first
- Experienced mappers are also asked to participate in validating completed tasks. Information on validating can be found here
Please see this HOTOSM Collate table for all the projects in this campaign as well as their completion status and priority.
Mapping Instructions
Imagery Instruction
- Use Bing Imagery as your first option. It is relatively the clearest and most updated imagery among the others in this area.
- However, keep checking the other imagery sources such as ESRI World Imagery if you have a tile that is either cloudy or has no high-resolution imagery available; please mark the task as "Bad Imagery" if none is available.
- Align the imagery with existing/mapped features if necessary. For further guidelines about correcting imagery offset, please see LearnOSM.
- You can also split tasks by selecting a tile in the Task tab and then clicking on the Split button; do this if you think a large tile will take longer to finish than the time you can dedicate to do the mapping.
Buildings
Quick Tutorial:
- How to Map Buildings
- Please accurately outline all the buildings you can find. The outline should be for the full size of the building even if trees in the imagery partly cover it.
- Take care not to include the building shadow in the building outline.
- After tagging as a building, please leave all the 'Fields' empty - this information is added later by local mappers.
- After drawing the outline and tagging it as a building, use the 'Q' key in the iD web editor to "square" the corners.
- Many buildings are very close but do not actually touch each other, try to map them close to each other without letting them connect or share nodes with each other, roads, or residential area outlines. In the iD web editor, holding down the "alt" key will keep nodes from "snapping" to each other and accidentally connecting.
- In the iD web editor, you will only have the option to tag new features as buildings, see below for editing or adding other features. If you have personal knowledge of a building, please add that information to the building, like the type of building (hospital, school, gas station, etc) or a name if it has one.
Saving
Please save when you make roughly 5 - 10 edits. This task will include some hashtags in the changeset comments, please do not delete these. After the hashtags make sure to add a description of what you did in this changeset. For example: Added a new residential road while fixing another road to better align with the imagery. Best practices can be found on the OSM Wiki here.
