Here in switzerland, we've had building shapes for decades (if not hundred of years). Here it what it looks like: https://map.geo.admin.ch/?topic=ech&lang=en&bgLayer=ch.swisstopo.pixelkarte-farbe&layers=ch.swisstopo.zeitreihen,ch.bfs.gebaeude_wohnungs_register,ch.bav.haltestellen-oev,ch.swisstopo.swisstlm3d-wanderwege&layers_visibility=false,false,false,false&layers_timestamp=18641231,,,&E=2537136.13&N=1152194.47&zoom=10 https://map.geo.admin.ch/?topic=ech&lang=en&bgLayer=ch.swiss... I've always found that kind of map way superior to the original "google like" maps. It's great to see that google is catching up, but I am really surprised that a database of building footprint is not something public like it is here in switzerland. Edit: Just discovered the time travel function, here in 1860: https://map.geo.admin.ch/?topic=ech&lang=en&bgLayer=ch.swisstopo.pixelkarte-farbe&layers=ch.swisstopo.zeitreihen,ch.bfs.gebaeude_wohnungs_register,ch.bav.haltestellen-oev,ch.swisstopo.swisstlm3d-wanderwege&layers_visibility=true,false,false,false&layers_timestamp=18601231,,,&E=2538102.48&N=1152776.83&zoom=8 https://map.geo.admin.ch/?topic=ech&lang=en&bgLayer=ch.swiss...
