Geographic Extent: Milwaukee, Ozaukee, Walworth, Washington, and Waukesha Counties in southeastern Wisconsin, covering approximately 2,071 square miles. Dataset Description: The SEWRPC 2015 LiDAR project called for the Planning, Acquisition, processing and derivative products of LIDAR data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base LIDAR Specification, Version 1.2. The primary set of deliverable data was developed based on the following two horizontal projection/datum systems as specified in the contract: NAD27 State Plane Wisconsin South Zone, US survey feet; NGVD29, US survey feet for Milwaukee, Ozaukee, and Walworth Counties NAD83 (2011) State Plane Wisconson South Zone, US survey feet; NAVD88, US survey feet for Washington and Waukesha Counties LiDAR data was delivered in RAW flight line swath format, and processed to create Classified LAS 1.2 Files formatted to individual 10,000-foot x 10,000-foot tiles. Tile counts are listed below: Milwaukee: 89 tiles in NAD27 Ozaukee: 85 tiles Walworth: 192 tiles Washington: 146 tiles in NAD83 (2011) Waukesha: 187 tiles Corresponding hydro-flattened Digital Terrain Model (DTM) files were created in Esri file geodatabase format. 1-foot contours were created from the hydro-flattened digital terrain model data and delivered in Esri file geodatabase format. Additionally, a secondary set of unclassified and classified lidar data was developed for the following counties: Washington County: 154 tiles in NAD27 State Plane Wisconsin South Zone, US survey feet; NGVD29, US survey feet Milwaukee County: 91 tiles in NAD83 State Plane Wisconson South Zone, US survey feet; NAVD88 (2011), US survey feet Ground Conditions: LiDAR collection began in Spring 2015, 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, Quantum Spatial established a total of 127 QC points that were used to calibrate the LIDAR to known ground locations established throughout the project area.
