Actually, all 3D models you can see were created by our photogrammetric software, mostly from aerial and drone imagery. However, we are able to incorporate data even from third-party sources - including 3D models, textures, DEMs, vector data, you name it.
Resulting maps can be easily easily embedded into your site or used in your web app so if you are interested, feel free to try it.
To get back from coordinates-finding mode, just click the 'eye' icon to the left from crosshair.
Thanks a lot for pointing this out!
