Enhanced Terrain Imagery of the Galax 30 x 60 Minute Quadrangle from Lidar-Derived Elevation Models at 3-Meter Resolution
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Galax 30 x 60 minute quadrangle in Virginia and North Carolina. The source data used to construct this imagery consists of 1-meter, 1/9 arc-second (3-meter) and 3-feet lidar-derived digital elevation models (DEMs). Lidar point cloud data (LPCs) were used to construct DEMs at a 3-meter resolution in parts of North Carolina. The lidar source data were compiled from different acquisitions published between 2018 and 2020. The data were processed using geographic information systems (GIS) software. The data is projected in WGS 1984. This representation illustrates the terrain as a hillshade with contrast adjusted to highlight local relief according to a topographic position index (TPI) calculation.
