LiDAR, which stands for Light Detection and Ranging, is a new technology that creates an interactive topographic map with elevation data accurate within eight inches. Historic statewide elevation data had an accuracy of within five feet. LiDAR is a process of scanning the earth with lasers from an aircraft to obtain accurate elevations.
