Surdex Corporation Unpublished Material Unknown Bureau_LiDAR vector data This project involved fixed wing aerial LIDAR data collected at a contracted point spacing of 0.70 meters for the Illinois County of Bureau totaling approximately 875 square miles. To acquire detailed surface elevation data for the Illinois Height Modernization Program (ILHMP) which is managed by the Illinois State Geological Survey (ISGS).

These vertical accuracies were tested using 105 independent survey check points in the following feature types: bare earth (21), Short Grass (22), Tall Grass (22), Trees/Forrested (20) and Brush (20). 0.194 feet RMSEz, 0.380 feet ACCz 95% CL bare earth, short grass USGS Quality Level 2 or better Acquisition was completed in early December 2015 using a twin engine Cessna 335 equipped with a Leica ALS70HP. Flight plan parameters were based on 6397 feet AGL, 40 deg FOV, 260,400 pulse rate, 20% sidelap, 0.67 meter NPS. Crews based out of IL Valley Regional and Kewanee Airports. All flights have calibration lines flown at beginning and end of flight perpendicular to lines captured during that mission. Base stations were continuously running during missions and placed so flight baseline never exceeds 25 miles. GPS-IMU captured during flight was processed using Waypoint's Inertial Explorer software. The bare-earth Lidar data was processed to USGS (NGP) Base Lidar Specifications V1.0 using the Terrasolid software suite. LiDAR point was initally processed with macros to locate bare earth ground, buildings and three classes of vegetation but was manually reviewed by experienced technicians in TerraScan or LP360 software for proper point classifciations in LAS tile format. Derivative product formats such as *.DAT, *.DGN, ESRI raster grid and TIN formats were produced using ESRI, Microstation and other software formats. Hydro features were collected on streams and rivers 100~ feet or wider and on lakes 2~ acres or larger. These lines were hydro flattened into the Lidar data and delivered in ESRI geodatabase file format. Unknown Surdex Corporation Wade Williams, CP Project Manager mailing and physical address
