I need help converting a download from Geofabrik to Illustrator. It had worked for me earlier, but I can't remember what I did, and now it doesn't.

  • I downloaded a country from Geofabrik (because city wasn't available) and now I want to extract three different cities (roads only) for an art project

  • its an 11GB .osm file

  • I Go to: Vector (menu) → OpenStreetMap → Import Topology from XML.
  • Then I get a .osm.db file
  • Then I do Vector (menu) → OpenStreetMap → Export Topology to SpatiaLite.... (and select the .osm.db file)
  • I select poly lines and my highway/road/lane tags
  • But at this state QGIS goes into a freeze (I have 12GB RAM). What now?

Will try those options. Meanwhile, the export seems to have happened, but the Map Canvas is blank. Anything I should know here?

My newly exported file is a new layer, has 1943641 feature counts etc, but MapCanvas is blank. How do I see the map, zoom to my area, and create a New Print Composer?

  • are you trying to export Topology oms sqlite data to the same sqlite db ? – Hugo Roussaffa - GeoDatup Oct 12 '17 at 8:09

I'd expect a country-sized 12Gb OSM import to take a while.

You could see if your city is one of those available from mapzen metro, that might cut the size down.

Or you could do a custom extract for a given area using bbbike, you may need to change the format from the default (protocol buffers) to Gzipped OSM XML, then unzip the download.
