Data Improvements in Ukraine
Task Description
This task outlines work to improve the map data in Ukraine. There are some issues with missing roads and highway alignment in Ukraine. In many places, imagery is slightly offset from ground truth. The OSM GPS trace layer in JOSM can show the correct alignment. In addition, we plan to do some edits to other feature types if necessary, such as buildings, water, and land use and other related polygonal features.
Improvements that will be addressed include the following:
- Correcting road connectivity and alignment issues and adding missing roads
- Improving road classification consistency according to global and local highway classification guidelines
- Correcting coastline and water features
- Adding missing buildings and land use as needed
- Other one-off fixes
Mapping Guidelines
The team will follow OSM and local policy, along with any other guidelines as appropriate. We also posted about this project on the OSM Forum for Ukraine to get feedback and suggestions.
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.
The team will use the imagery and data sources specified below for mapping in Ukraine.
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 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.
Sources
The team will use the imagery and data sources as available including:
- DigitalGlobe Standard/Premium
- Bing imagery
- Mapbox imagery
- ESRI imagery
- HOT task imagery, if available
- Mapillary
- OpenStreetCam
- Pic4Carto
- Telenav's MissingRoads plugin and ImproveOSM
- Strava and OSM GPS traces
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.
How can you help
We have posted a number of MapRoulette challenges related to issues with the road network.
