The Center for Advanced Spatial Technologies (CAST), University of Arkansas advances research, education, and outreach about geoinformatics, geomatics, and related digital data techniques (e.g., GIS, geospatial modeling, high density survey, remote sensing, etc.). The center, in collaboration with NSF, announced the Spatial Archaeometry Research Collaboration (SPARC) program to further the promotion of geospatial research in archaeology.

CAST recently published 3D scans of several famous archaeological sites through tDAR to publish the center’s work. As part of a Digital Antiquity grant project, CAST researchers curated scan data from high-density surveys at Machu Picchu, Peru; Tiwanaku, Boliva; Ostia, Italy, and Stabiae, Italy.

CAST’s 3D scans allow you to experience the built environment of these incredible places. Moreover, the center’s data allow researchers and interested users to conduct metric analyses of scanned structures and features.
