PI: Wetherbee Dorshow, University of New Mexico. The area of interest is defined by an irregular polygon with an area of 39.3 km2. The polygon follows a segment of the Chaco Canyon, NM and is located approximately 160 km northwest of Albuquerque, NM and 85 km Southeast of Farmington, NM. The data were collected to simulate dynamic hydrological processes in archaeological contexts.Publications associated with this dataset can be found at NCALM's Data Tracking Center Dataset Acknowledgement: Lidar data acquisition and processing completed by the National Center for Airborne Laser Mapping (NCALM).
