Applying photogrammetric mapping: A case study from northern New Mexico

Photogrammetric mapping, the creation of detailed maps from aerial photographs, offers advantages to archaeologists that have not been fully utilized in recent years. Photogrammetry provides an efficient and cost-effective way to map extensive, complex sites. Common field problems such as obsolete equipment, unskilled staff, limited field time, and inhospitable field conditions are reduced accordingly. The usefulness of photogrammetry is demonstrated through work at the site of Pueblo Blanco, New Mexico, occupied ca. A.D. 1370-1525. A photogrammetric map was used to calculate total site size and the number of stories in each block of rooms. Further the map supports nra ongoing effort to stabilize the site and monitor the locality for looting and serves as a planning document for management of future uses.
