Original Data Collection:
Dewberry collected 822 square miles of lidar data in Pasco County, Florida. The nominal pulse spacing for this project was 1 point every 0.25 meters or a nominal pulse density of 8 points per square meter. Dewberry used proprietary procedures to classify the LAS according to project specifications: 1-Unclassified, 2-Ground, 6-Building Rooftops, 7-Low Noise, 9-Water, 17- Bridge Decks, 18-High Noise. Geometrically unreliable points, ground points within 2 feet of breaklines, and ground points within 3 feet of building rooftops have been identified with the Withheld Flag. Overage points have been identified with the Overlap Flag. Final lidar deliverables are in LAS v1.4. The data were tiled according to the Florida Statewide Lidar Index tiling scheme with each tile covering an area of 5,000 feet by 5,000 ft.
In addition to the lidar point data, bare earth Digital Elevation Models (DEMs) at a 2.5 ft grid spacing, created from the lidar point data, are also available from the NOAA Digital Coast Data Access Viewer (DAV). A link to the bare earth DEM data is provided in the URL section of this metadata record.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
