It remains to be seen whether this inflames the “get data for free” mentality or makes more people (esp. PlaceMaker turns this huge amount of data into a (nice) business model (two years ago I had made a prototype of a building outline importer and know the significant necessary cleanup and estimation of missing data I finally couldn’t figure out how to upload new building footprints back to OSM). However it is often forgotten that also this data is not free as beer, but costs “give back”. Various attempts to incorporate 3D models have not yet advanced either on technical issues (hosting, wiki-editing), building a community and low coverage of the world (like Google’s first attempt). This is parametric data, not geometric data what people know from 3D Warehouse, but it should suffice for architectural purposes and city planning. 2D outlines (nodes, ways, relations, tags) that may be augmented with tags that define the building height or classify the roof, building type etc.The mentioned open source solution (OpenStreetMap) has following type of data: The data is not available (and if so, it would cost licensing fees). Google bought its oblique aerial imagery from commercial data providers and later obtained it from their own flights. These do not distinguish buildings as individual objects and priorize photorealism over accuracy. 3D mesh data from oblique aerial scans.Also take a look at “ Find nearby models” in SketchUp’s component browser. The models however are publicly shared in 3D Warehouse, and available for individual download (despite the unclear licensing situation, and for data scraping see ToS). I wouldn’t base a business workflow on a bet that the old Google Earth will be updated for a few years. The future of Google’s Earth is the consumer-oriented browser map. These models can only be enabled in the advanced configuration options of the old now non-Google Earth ( GitHub - google/earthenterprise: Google Earth Enterprise - Open Source). deprecated individual building models from 3D Warehouse.In case of Google Earth, there are two types of data to distinguish (as already mentioned): You would have to deal with the question of who owns the data and whether you can re-use it under some license (to avoid stealing). He asks how to extract somehow all the data, and not asking whether it is possible or available. There is one fundamental issue in the first poster’s request:
