LiDAR for the Domain

lidarLast spring, Sewan‌ee started a LiDAR imaging project with the goal of producing highly detailed contour maps for the entire Domain of Sewanee: The University of the South. A plane flew a LiDAR imaging device across the Domain so that there were multiple points for each square meter of land. Some of these points represent trees, shrubs, and buildings, while others reach the ground.

‌Sara Smith (C'15), pictured below, spent last summer in San Francisco, California in a GIS and environmental research lab learning the techniques to turn the raw data into useable contour maps. She also was able to produce an estimate of the number of trees on the Domain - there are over 1.2 million. Now back at Sewanee, Sara is spending this semester working with Dr. Chris Van de Ven, instructor of GIS, to make the LiDAR maps accessible to students and faculty for use in research.
