While trying to drawn down the backlog of flagged atlases and create some new ones, I’ve run across some specific boundary-related inaccuracies:
- The Bonin Islands (or Ogasawara Islands) don’t appear to be included in the atlas polygons at all
- The Volcano Islands to their south are included in Shikoku. Both island chains are part of Tokyo prefecture, IIRC.
- The polygon for Isla Tortuga, east of Baja California, is located in the wrong place
- The polygons for the Channel Islands (between Britain and France) are located in the wrong place.
