I am interested in the number of buildings found within each protected area in Africa. I have a protected area layer (WGS84) that I am using. The amount of data per protected area will be very small, most likely less than 200 nodes per protected area.

However, I cannot find a GIS tool (either QGIS or ArcGIS) that will allow me to download OSM data for multiple polygons from a vector layer at once, despite the data being very small. I did see that ArcGIS has an option under the OSM editor “Extent of data download” dropbox for intersection or union of inputs but these do not seem to work.

  • Does it need to be directly downloaded from OSM? – hannbroo Oct 30 '18 at 23:45
  • I doubt that work but you may try to transform your multiple polygons to one multipart polygon – J.R Sep 11 at 16:13

There is currently no direct way of downloading in qgis. the hot export tool has the option to upload a geojson file and download data from it.

  • Thanks for the link but that tool still does not allow for more than one polygon's data to be exported at once. – Kevin May 15 '18 at 11:54
