Service Description: Product: Bare earth Digital Elevation Model (DEM) data. Geographic Extent: Atlantic, Cape May, Cumberland, Ocean, Salem counties New Jersey, covering approximately 2,545 square miles. Dataset Description: USGS South NJ Lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.5 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.3. The data was developed based on a horizontal projection/datum of NAD83 (2011), State Plane New Jersey, feet and vertical datum of NAVD88 (GEOID12B), feet. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 3,079 individual 5000 x 5000 foot tiles, as tiled Intensity Rasters, and as tiled bare earth DEMs; all tiled to 3,079 individual 5000 x 5000 foot schema. Ground Conditions: Lidar was collected in early 2019, while no snow was on the ground and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Sanborn Map Company, Inc. established a total of 30 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. An additional 142 independent accuracy check points, 80 in Open Terrain/Bare-Earth and Urban landcovers (80 NVA points), 62 in Grass, Brush and Trees categories (62 VVA points), were used to assess the vertical accuracy of the data. These check points were not used to calibrate or post process the data.
