I am trying to build a map with the footprints of the buildings using QGIS. So far, it was straightforward to import OSM file generated by OpenStreetMap, but unfortunately, the map is not complete. There are only a few buildings that are available, as you can see in the image below:
So far I couldn't find any vector map that would show those buildings. I saw in a previous post that there exist such a map on this website (see image extract in the picture below).
The problem is that the map was built in Flash and I cannot extract it as vector data. I can see however that the map was built in ArcGIS and I was wondering if there is any way to get such a map for QGIS. I have tried importing and *shp from here, but it is the same as in the first picture. My knowledge ended there, and I have realized that I don't even know how to search for such a vector map with all the buildings.
Can anyone help me with this or guide me on how/where to search for such a map?
