Service Description:

Product: These lidar data are processed Classified LAS 1.4 files, formatted to 6,956 individual 2000 ft x 2000 ft tiles; used to create intensity images, 3D breaklines and hydro-flattened DEMs as necessary. Geographic Extent: Adams County, Illinois, covering approximately 925 square miles. Dataset Description: Adams County, Illinois project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.7 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83, State Plane, Feet and vertical datum of NAVD88 (GEOID12B), Feet. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 6,956 individual 2000 ft x 2000 ft tiles, as tiled Intensity Rasters, and as bare earth DEMs. Ground Conditions: Lidar was collected in April 2018, 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, Michael Baker International established a total of 31 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. An additional 64 independent accuracy check points in Open Terrain and Urban landcovers were used to assess the vertical accuracy of the data. These check points were not used to calibrate or post process the data.
