The Center was been involved in a multi-year project in collaboration with Dr. Alexei Vranich at the University of Pennsylvania to scan and document the Pre-Incan site of Tiwanaku, Bolivia. As part of that documentation, historic aerial photographs from 1972 were purchased and processed to created several GIS data layers. These images are low altitude and there fairly high resolution. They can be processed using LPS or PhotoScan (PhotoScan Pro if control is to be used).
Read a short synopsis of the project at Tiwanaku Project Details and for full details on the entire survey, refer to Geophysics and Geomatics at Tiwanaku.
