  "description": "Product: These lidar data are processed Classified LAS 1.4 files, formatted to 16,801 individual 1000 m x 1000 m tiles; used to create intensity images, 3D breaklines and hydro-flattened DEMs as necessary.  \n\nGeographic Extent:  Bay, Calhoun, Covington, Decatur, Dixie, Escambia, Franklin, Gadsden, Geneva, Grady, Gulf, Holmes, Houston, Jackson, Jefferson, Lafayette, Leon, Liberty, Madison, Okaloosa, Santa Rosa, Seminole, Taylor, Thomas, Walton, Wakulla, Walton, and Washington counties, Florida, covering approximately 5,953 square miles.\n\nDataset Description: FL Panhandle 2018 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 meter. Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 1.3. The data was developed based on a horizontal projection/datum of NAD83 (2011), Albers Equal Area, meters and vertical datum of NAVD88 (GEOID12B), meters. Lidar data was delivered as processed Classified LAS 1.4 files, formatted to 16,801 individual 1000 m x 1000 m tiles, as tiled Intensity Imagery, and as tiled bare earth DEMs; all tiled to the same 1000 m x 1000 m schema. \n\nGround Conditions: Lidar was collected in early 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, Airborne Imaging used 30 control points (16 FL DOT FPRN stations, 5 NGS monuments, and 9 newly established base stations) to control the lidar acquistion and tie the lidar to known ground locations established throughout the FL Panhandle project area.  Over 15,000 GNSS kinematic points were used by Airborne Imaging to verify accuracy of the calibarted lidar data.  In addition a full AOI will be tested with 262 independent accuracy checkpoints, 152 in Bare Earth and Urban landcovers (152 NVA points), 110 in Tall Grass and Brushland/Low Trees categories (110 VVA points), but the interim accuracy of Block 1 was tested with 22 in Bare Earth and Urban landcovers (22 NVA points), 12 in tall Grass and Brushland/Low Trees categories (12 VVA points), were used to assess the vertical accuracy of the Block 1 data. These checkpoints were not used to calibrate or post process the data.\n\nIn addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data and the breaklines are available for download at the links provided in the URL section of this metadata record.",
