Merrick-Surdex Joint Venture, LLP 20221228 raster digital data A two-foot (2ft) cell size Intensity raster was created from all lidar returns. The files are delivered in 2000ft by 2000ft tile format, The rasters are delivered in GeoTIFF .tif format. Base Specification 2021 rev. A with a Aggregate Nominal Point Spacing (ANPS) of 0.5m or less. These are 8bit unsigned integers. This task is for providing a spring 2022 leaf-off and snow-free lidar survey over an Area of Interest (AOI) of approximately 9,013 square miles in central and northeastern Illinois. This Task Order will support the National Resources Conservation Service (NRCS) agricultural resource mapping and soil survey programs, and the 3DEP mission. The following will describe the proposed services and associated revised costs to successfully complete the mission. The IL_East WU area 300136 is approximately 2126 square miles.

None. However, users should be aware that temporal changes may have occurred since this dataset was collected and that some parts of these data may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of its limitations. Acknowledgement of the U.S. Geological Survey would be appreciated for products derived from these data. Data covers the entire area specified for this project. The dataset was reviewed to ensure completeness and accuracy. Using MARS software a two-foot (2ft) Intensity GeoTIFF .tif file was created using the Intensity values of all returns minus the overlap points. The files are delivered in 2000ft by 2000ft tiles. These files are 8-bit unsigned integers. 20221228 Raster Pixel 2000 2000 NAD 1983 2011 StatePlane Illinois East FIPS 1201 Ft US 0.999975 -88.33333333333333 36.66666666666666 984250.0 0.0 row and column 2.0 2.0 foot_us NAD83(2011) GRS 1980 6378137.0 298.257222101 North American Vertical Datum of 1988 Geoid2018 0.001 foot_us Explicit elevation coordinate included with horizontal coordinates 20221228 Merrick-Surdex Joint Venture, LLP mailing and physical address
