Modify geometry of buildings, lots, and other features

You must edit the geometry at OpenStreetMap, our open data repository provider, and notify us via our web form

  1. On OSM
    1. Create an account on osm.org if you have not already done so
    2. Go to the area you’d like to edit and hit edit, or click on this link
    3. Make changes to geometries using the editing interface
    4. Use UD specific attributes so the feature can be identified by the system, such as “udcode” (value will be the actual/official UD Building Code)
    5. Save your change in OSM
  2. Finally, fill out our webform to let us know to re-render the map
