I have downloaded some open street map data from Webgeo, but instead of coordinates it came with an "OSM_ID". I cannot seem to find any data dictionary or information about this variable on the web. Does anyone know what it is and how do I convert it to coordinates? An example of the data is as follows:

1432784186,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,St Aubin,,,,,village,,,,,,,,,,,,,,,,,,,,,,,
1787222125,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,London Berth,,,,,locality,,,,,,,,,,,,,,,,,,,,,,,
1787082727,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,South Pier,,,,,locality,,,,,,,,,,,,,,,,,,,,,,,

Thanks for any help

  • In which format did you download it? Jun 10, 2013 at 7:18
  • I downloaded it in CSV. The above is a subset.

If you don't want to reload the whole data, you can query the Overpass API http://www.overpass-api.de/query_form.html with

  <id-query ref="507464799" type="node"/>

for the OSM_IDs you got.

  • Wow, this seems a very powerful tool (wiki.openstreetmap.org/wiki/Overpass_API) but I was hoping for a simple wizard, as my app is almost finished but for the data. It seems something definitely worth getting familiar with though. Thanks for your help.

  • This is what I used in the end.

  • Since overpass API is cool, there is also a URL for it: overpass-api.de/api/…

OSM_ID is the global and unique identifier for OSM objects. What you have downloaded from Webgeo must be a processed version, where someone has removed the coordinates, but kept only the tags and values, stored in a CSV-format.

Original and full data can be downloaded from http://download.geofabrik.de/.

Please notice even the SHP version is a processed one, where not all the details are in place (but coordinates are there). You need PBF/BZ2 files to get ALL details.

  • Thanks for that. It is useful to have a source for bulk downloads, but I was hoping for a simple method of downloading subsets.
