[Processes][GetOpenStreetMapBuildingData] Missing buildings in converted file #2

Open JusteRaimbault opened 11 months ago

JusteRaimbault commented 11 months ago

When using the collection script for Toulouse in 2020, with a conversion from osm to shp, buildings with holes (made of several ways, outer and inner) are missing - this may be an issue during the conversion with ogr2ogr

Furthermore, the corresponding shp seems to be invalid in some cases, with non valid linear rings and with linestrings that should be polygon; is this an issue with the OSM ogr driver?

Compared with results obtained using osmnx, there seems to be some bugs in the ogr driver for osm: a building not in the exported shp nor in qgis visualisation which uses ogr, is indeed in the osm file and in the dataframe produced by osmnx. Switching totally to osmnx may be an option (also allowing a stronger integration with python).
