WikiProject Uganda/Import Kampala Capital City Authority Data Workflow
In this wiki we will:
- present the general import rules in OSM, then the data itself, the tool set to make the import, and the extra data that will be added as a useful complement.
- describe step-by-step a workflow to make the import, with screenshots and tips.
Presentation
Import rules in OSM
The data from the Kampala Capital City Authority, considering its high quality, is to be imported into OSM and consequently, needs to follow the guidelines of any to-be-imported dataset.
The dataset has been analyzed, the attributes have been converted into tags, presented and validated to the imports mailing list.
Any import will be done through a specific OSM user account. So the advice is to create a new OSM user account (eg the usual name with _import at the end) from a secondary email address.
Only data that has been verified through data collection, high resolution imagery and mapillary images, or the resulting nodes when merging with existing OSM nodes, will be uploaded using this account.
The Kampala Capital City Authority data
According to the Kampala Capital City Authority: "These data was collected between 2011 and 2018, based on Arc1960 UTM 36S, for the sole purpose of city better planning, management and administration. Therefore, it should be used cautiously within its limitations."
The original data set consists of the following.
| Feature | Number |
|---|---|
| Buildings | 35538 |
| Roads | 737 |
| Marketplaces | 5 |
| Drainage | 1546 |
| High Voltages Poles | 883 |
| Hv lines | 926 |
| Low Voltage Lines | 3289 |
| Low Voltage Poles | 4961 |
| Transformers | 172 |
| Informal Settlements | 16 |
| Land Use | 91 |
| Schools | 198 |
| Street Light | 272 |
| Hill tops | 2 |
| Spot heights | 4 |
| Wetland | 2 |
During the import we will put changeset tags that indicate the source. Nonetheless, it is useful to keep the source tag for each object as the changeset information is not forcefully got from any OSM extract tool and KCCA could be disappointed not to be mentioned for this data + the metadata can disappear easily once the information is shared and shared, and the source can be a very useful information for people who will work with these data.
