Importing russian places from GNS

NGA GEOnet Names Server is public domain datasource that contains a huge amount of geographic names and coordinates

Importing places from http://earth-info.nga.mil/gns/html/cntyfile/rs.zip

Converted osm files can be found at http://upliner.openstreetmap.ru/gns/

The datasource contains:

  • Towns/villages
  • Railway stations
  • Lake/reservoir names
  • Populated places have region membership data. Therefore rough region boundaries can be drawn.
  • Many other useful geonames

Unfortunately, there are no population information, performing following actions:

  • Most towns and largest villages were already imported from VMAP0. So default tag for populated places is place=hamlet
  • For all ADM2 if there was a populated place with the same name it was assumed that it is district center and probably should be marked as place=town
  • Using GNS data to correct existing data, especially populated places imported from VMAP0. There are some outdated place names and VMAP0 coordinates are very inaccurate.
  • Using Landsat data for revision of results and correcting place types
  • As the coordinates have relatively low resolution, some places shared the same point. In case of such duplication, both places are usually deleted.

The quality of the data is not very good but it should serve as scaffolding in this early stage of the map.

Import progress

  • By Feb 18 fully imported Ryazan region and some boundaries
