This task outlines work to improve map data in South Korea based on app user feedback. We occasionally receive anonymous user feedback, often related to street names, addresses, road network issues, points of interest and other related features. We plan to correct the data where we can identify that the feedback is valid, using other sources as appropriate listed below. As necessary, we also plan to update and correct major issues or vandalism of roads, 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.
We do not anticipate making many edits, but wanted to let the community know.
This may include:
Correcting road connectivity issues and network issues such as missing roads and alignment according to local and OSM guidelines
Correcting coastline and water features
Adding addresses
Adding or correcting buildings and land use
Other one-off fixes
Mapping Guidelines
The team will follow OSM and local policy, along with any other guidelines as appropriate. The team will correct the data using the imagery and data sources specified below as needed.
Some coastlines are connected to lower level subnational administrative boundaries. In that case we will adjust the boundary with the coastline. These are not country boundaries, but things like place, district and county.
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.
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.
We have also messaged the OSM forum for South Korea to get feedback and suggestions about the project
Our team uses the hashtag #adt (for Apple Data Team) for our edits.
Area of Focus
Throughout the country
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.

Mapping Guidelines
The team will follow OSM and local policy, along with any other guidelines as appropriate. The team will correct the data using the imagery and data sources specified below as needed.
For water and coastlines, the team will follow OSM coastline guidelines, waterways policy such as water and natural=water and local policy along with any other policy as appropriate.
Some coastlines are connected to lower level subnational administrative boundaries. In that case we will adjust the boundary with the coastline. These are not country boundaries, but things like place, district and county.
Where we see them, we will remove the

The team will apply image offsets as needed.
Changeset Comments
The team will provide changeset comments that are in compliance with OSM changeset guidelines.
Where needed, the team will tag corrections with
review_requested=yesso the local community can double check them.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.
