I have OpenStreetMap data loading failure problem. I want to use the Download OpenStreetMap data tool in QGIS. I want to select the extent from map canvas like shown below:

enter image description here.

For me, the osm-data usually works when the data downloaded map was less then 1:160000 scale. But when it is bigger than 1:320000 scale (including 1:320000), QGIS always gets infinite loading circle rainbow (OS X user).

Does anyone have an idea on how to get it to work?

QGIS and the server behind Overpass API are not able to handle large area requests.

If you need that amount of data, think about

  • downloading pbf extracts from Geofabrik
  • filter the data for the items you really want with direct Overpass API calls
  • set up a local postgis database for your area of interest with a suitable Geofabrik extract
  • As you told me about extracted pbf, I tried to load it by adding new vector layers but, it doesn't work with multi polygons, multilinestrings and lines. Any Idea ? Thanks for the answer though.

  • Polygons are yet an issue, but lines should be imported. You have to select the layers you want by clicking them. Start with a small extract, as QGIS has to keep everything in RAM. Using a postgis database is the best way to get all polygons the way they are rendered in mapnik, even for larger areas. But I have no experience with Postgis on Mac.
