I want to share my experiment. It allows sodavat model natural terrain. Here I took the example of Utah, Arches National Park, coordinates 38 ° 41'59.04 "N, 109 ° 33'13.56" W. For this I used Google Erth, program FotoSkan Agisoft whose site http:
//www.agisoft.ru. There you can download a free 30-day trial. In the program Google Erth I "circled" the object at an angle of around making at regular intervals PrtScr in quantity of 45 pieces. Next, I uploaded these pictures in the program PhotoScan and processed them there by the proposed method. And then export the model in the format of Obj. with the texture of the images constructed. Places texture has blur, but it's the lack of the original. You can try to select objects with a higher quality texture mapping in Google Erth. Hope I did not violate anyone's rights, especially as the model remained inscription Google, it is not visible in the frame, below left. If it's someone seems interesting, I'll try to answer your questions.
