This is a project page from the OSM UG Guidlelines Workgroup logo.svg Ugandan OSM Guidelines & Training Workgroup.
Please adhere to the intentions and editing guidelines as developed by the workgroup. It will allow the Ugandan local community to develop common local mapping and tagging guidelines, training materials and improve the quality of the map in Flag of Uganda.svg Uganda. All materials and opinions are established with support and consensus from the local community.

Issue: No common strategy

Critical
Critical
 

Description: There is no common strategy how to define offsets and calibration points.

Solution: We clearly define the globally accepted strategy of "ground truth". We describe how to define offsets based on nearby GPS tracks. Describe the cases when GPS tracks are too far or inaccurate and not acceptable or accurate enough to create an offset.

Issue: HOTOSM considers Bing as golden standard

link=}}}
Important
 

Description: HOT has a strategy based on "Armchair mapping" and Bing as "Golden Standard". This does not comply with the OSM philosophy of "Ground Truth" = GPS tracks and field mapping and does not describe alternative sources like Mapillary, KartaView/OpenStreetCam and Strava.

Solution: Notify HOT to remove this non-compliant golden standard. They should comply with the global or local guidelines. Project manager should supply offsets and calibration points or sufficient GPS data to determine accurate offsets or calibration points.

Issue: Use Imagery Offset Database

link=}}}
Important
 

Description: Use of OSM Imagery Offset Database with JOSM or as JSON datasource is unknown & inconsistent. Only a small part of UG is covered.

Solution: Promote the use and refer to the available training and description of the Imagery Offset Database (OSM Imagery Offset Database).

Issue: Centralise and improve training materials

link=}}}
Minor
 

Description: Training materials are spread across different sources and to general.

Solution: Make one central training page and make infographics to support non-professional or less experienced OSM users.

Issue: QA and resolution strategy missing

Critical
Critical
 

Description: Training materials are spread across different sources and to general.

Solution: Define the tools and how to use them for QA purposes. Provide procedures to resolve misalignments.
