OSM data doesn't have a fixed number of attributes.

If you need to get "all" tag information from a specific OSM extract in to a fixed format column format you will need to first do a pass over the file to determine all keys that are present, or simply write a small script that does this in one pass (which might be a bit painful for a large extract).

As Simon said, you need to know the structure before you can create a csv. I can imagine some sort of parser to do this, but that only makes sense if you often have this problem. What I would do myself is use the PBF download from Geofabrik, then convert to spatialite. This can then easily be queried in QGIS. Common tags already are their own column, less common tags are merged together in an "other tags" column. These can still be queried with some creativity, but you can also edit the config file behind the process to get the columns straight into your spatialite database.

Here's a step by step:

  • Download OSGEO4W (if you're on windows, and don't use GDAL/OGR already):
  • Install and make sure to include GDAL and QGIS.
  • Open the Osgeo shell. An icon should have been added to your desktop.
  • It looks just like a DOS terminal. Use the cd command to navigate to where your .pbf is
  • This command will create your spatialite database:

    ogr2ogr -f SQLITE -dsco SPATIALITE=yes yourdatabasefile.sqlite themapyoudownloaded.osm.pbf

  • You can use the sqlite file in an easy program like Gaia GIS. This will often work better than QGIS for heavier data manipulation.

  • You can drag and drop the data into QGIS and query the data there to create map layers.
  • Exactly how the data is treated in the conversion from PBF to SQLITE is defined in osmconf.ini (if you have more than one QGIS installs, you might have several of these files!). This is quite easy to adapt to your needs.
