Product: These lidar data are processed Classified LAS 1.4 files, formatted to 4,737 individual 1000 m x 1000 m tiles; used to create intensity images, 3D breaklines and hydro-flattened DEMs as necessary.
Geographic Extent: Florida counties of Broward, Collier, Hendry, Miami-Dade, Monroe, and Palm Beach, covering approximately 1,641 square miles.
Dataset Description: Florida Southeast Lidar project called for the Planning, Acquisition, processing and derivative products of lidar data to be collected at a nominal pulse spacing (NPS) of 0.35 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.3.
Ground Conditions: Lidar was collected on June 2, 2018, November 28, 29, 30, and December 6, 7, 12, and 17, 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, Dewberry established a total of 20 ground control points that were used to calibrate the lidar to known ground locations established throughout the Broward, Collier, Hendry, Miami-Dade, Monroe, and Palm Beach counties, Florida project area. An additional 125 independent accuracy checkpoints, 69 in Bare Earth and Urban landcovers (69 NVA points), 56 in Tall Grass and Brushland/Low Trees categories (56 VVA points), were used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data. The project consists of 4,737 tiles but one DEM was not delivered because it is a water only tile.
