Integration of Photogrammetry and Terrestrial LiDAR

Much of CAST's research efforts involve new approaches to spatial data and the development of new methodologies for analysis of these data. The integration of photogrammetrically derived spatial data and terrestrial LiDAR (often referred to as HDS) is a perfect example of this effort. The methods of integration developed have led to a comprehensive site model for Tiwanaku, Bolivia. This site model includes data from not only photogrammetric processing and LiDAR, but also data from a geophysical survey, a total station survey, and historic topographic data from 1911. Together, this data tells a story that no one data set can tell. One of the biggest benefits experience from this model has been the increased ability to interpret geophysical data (data collected by ground penetrating archaeological instruments that detect objects within 3 meters of the surface).
