LiDAR Point Cloud - Township 44N Range 9E (laz)

Metadata Updated: June 14, 2019

Industry standard .las LiDAR (Light Detection And Ranging) classified points. This LiDAR data was collected using Leica's ALS50 Phase I sensor. The raw data was verified in Merrick and Company's LiDAR software (MARS) for complete coverage of the project area, and boresighted to align the flightlines. Raw data files were parsed into manageable client-specific tiles. These tiles were then processed through automated filtering that separates the data into different classification groups: unclassified points, ground points, breakline proximity points, [HTML_REMOVED]noise[HTML_REMOVED] points and water. The data was next taken into MARS to reclassify the erroneous points that may remain in the LiDAR point cloud after auto-filter.The horizontal datum used is the North American 1983 HARN. The vertical datum is the North American Vertical Datum of 1988. The projection is Illinois State Plane, Eastern Zone, using US Survey Feet as units.In order to reduce the download times of these files we have compressed them with LASzip. A free decoder is available from the website http://www.laszip.org.
