This task outlines work to improve map data in Gambia. We plan to work on improving the road network, such as adding missing roads, fixing network issues such as missing connections or crossing roads, and other related issues. We also plan to update and correct coastline and water features as we find them, and correct and improve land use and land cover polygons where needed, such as airports, national parks, forests, colleges and universities, and so on -- remove duplicates, correct the boundaries, fix incorrect tags and other similar things.
Improvements that will be addressed include the following:
Improving road classification consistency according to Africa and OSM guidelines
Adding missing roads
Correcting road connectivity issues
Improving road classification consistency according to local and OSM guidelines
Correcting coastline and water features
Adding or correcting land use polygons
Other one-off fixes
Mapping Guidelines
The team will follow OSM and local policy, along with any other guidelines as appropriate.
For water and coastlines, the team will follow OSM coastlineguidelines, waterways policy such as water and natural=water and local policy along with any other policy as appropriate.
Some coastlines are connected to administrative boundaries, in which case we will adjust both if appropriate
Where we see them, we will remove the source=PGS tag, which was from an earlier coastline import that needs to be cleaned up. We received a message on the India coastlines project requesting this, and it is commonly done in other coastline improvement edits.
The team will use the imagery and data sources specified below as needed for mapping in the country.
When in doubt, the team will use the existing tags and data which are used locally. The history in JOSM (ctrl-H) identifies what previous mappers added and their notes and/or explanations regarding changes made. This history can also show if a previous mapper has visited that area or has expert knowledge or sources.
Our team uses the hashtag #adt (for Apple Data Team) for our edits.
Area of Focus
Throughout The Gambia.
Tools
The team will use JOSM for completing the task. JOSM has validation warnings for road networks and other possible issues that are important to prevent improper changes.
Our community lead is Teddy Ahlvin and our editing leads are Jon Westlake and Erica Olson.

Sources
The team will apply image offsets as needed.
Changeset Comments
The team will provide changeset comments that are in compliance with OSM changeset guidelines.
Error Detection
The team will check for errors visually and using JOSM validation warnings prior to committing the changeset.
In addition, the team will review its work in accordance with validation guidelines such as the OSM Wiki and LearnOSM validation guidelines
