Enhanced Terrain Imagery of the White Clay Creek Watershed from Lidar-Derived Elevation Models at 1-Meter Resolution

August 27, 2021

This imagery dataset consists of 1-meter resolution, lidar-derived imagery of the White Creek Clay watershed in Pennsylvania and Delaware, which includes part of the Delaware River Basin. The footprint of this dataset covers USGS Hydrologic Unit Code (HUC) areas HUC 12-020402050301, HUC 12-02040205030102, HUC 12-02040205030103, HUC 12-02040205030106, and part of HUC 12-02040205030108. The source data used to construct this imagery consist of 1-meter Lidar-derived digital elevation models (DEM). The Lidar source data were compiled from different USGS acquisitions published between 2013 and 2015. The data were processed using geographic information systems (GIS) software. The data are projected in North America Datum (NAD) UTM Zone 18 North. This representation illustrates the terrain as a hillshade with contrast adjusted to highlight local relief according to a topographic position index (TPI) calculation.
