Is it possible to extract all 3d data (terrain + objects: buildings, vegetation, landmarks, etc.) from Google Earth in an easy way and 3d print it? I found tutorials about extracting the terrain itself, but I would like to print a section of a city which is nicely populated with detailed models. Since it would still cover a larger area, downloading and printing the buildings separately is not an option.
In case anyone else has this question, I found a way at least to export an area (up to 800m x 800m per file) of buildings at once from Google Earth (well, from OSM, which is the source of most of the buildings in GE). I don't know if it takes terrain variations into account (at that resolution, inside a city there probably isn't so much variation anyways):
