When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".

Trace the building footprints as accurately as possible using Bing satellite imagery using JOSM.

  • Read the guide: mapping buildings in JOSM
  • The polygon must match the base of the building as close as possible as inferred from the reference Bing imagery
  • Use the building tool (b) to quickly trace buildings parallel to each other
  • Double click with extrude (x) to create extrusions

If you are unfamiliar with OSM and JOSM, read the mapping guide: https://www.mapbox.com/mapping/
