Description
Lidar was acquired on Oct 7+8, 2019. Lidar was calibrated and was based on NAD83 and CGVD28 datum using UTM 14 North projection and was classified. The classified data was used to create the DEM using the following classes: 2 (ground), 9 (water). Dem was created at a 1m resoultion and then exported out as a Geotiff with 32 bit floating elevations. Images were cut into tiles based on 5km x 5km index.
