OSM basemap and building footprints

[HeatherShearer55]

Hi, I use Pro v2.9. The OSM basemap has (visual) polygons for building footprints. However, when you download OSM buildings data either from Geofabrik, Living Atlas, GetOSMData, using QGIS plugins, etc., the basemap has many more building footprints. Does anyone know how to get ALL the building footprints that are shown in the basemap (for a city in Australia)? I can of course get them from LIDAR sources, various deep learning libraries or using one of the Copernicus indices, but those are very slow to use on a large dataset (+-500k properties). 

Example given in image attached, showing the basemap and the OSM shapefile

OSM extracts don't include the other Daylight stuff. If you're looking for ways of extracting OSM data, start with the OSM wiki:

https://wiki.openstreetmap.org/wiki/Planet.osm

There are lots of ways to get at the data. For example, I use imposm to pull data from OSM, and using a limitto parameter, specify a small area of interest (my home county). This is able to stay up to within 5 minutes of the main OSM database, and is fairly lightweight, running in the background of my desktop machine.
