Original Dataset Product: These lidar data are processed Classified LAS 1.4 files, formatted to 2690 individual 1500 m x 1500 m tiles; used to create intensity rasters, 3D breaklines and hydro-flattened DEMs as necessary. Original Dataset Geographic Extent: Cayuga, Jefferson, Lewis, Orleans, Oswego, St. Lawrence, and Wayne Counties counties, New York, covering approximately 2337 square miles. Original Dataset Description: The 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 v2023, Rev. A. The data was developed based on a horizontal projection/datum of NAD83 (2011), Universal Transverse Mercator, meters and vertical datum of NAVD88 (GEOID18), meters. Lidar data was delivered as flightline-extent unclassified LAS swaths and as processed Classified LAS 1.4 files, formatted to 2690 individual 1500 m x 1500 m tiles, as tiled Intensity Rasters, and as tiled bare-earth DEMs; all tiled to the same 1500 m x 1500 m schema. Ground Conditions: Lidar was collected in spring 2023, 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, Sanborn Map Company, Inc., established a total of 28 ground control points that were used to calibrate the lidar to known ground locations established throughout the project area. An additional 150 independent accuracy checkpoints, 84 in Bare Earth and Urban landcovers (84 NVA points), 66 in Tall Grass and Brushland/Low Trees categories (66 VVA points), were used to assess the vertical accuracy of the data. These check points were not used to calibrate or post process the data. This dataset was downloaded by the NOAA Office for Coastal Management (OCM) from the New York State GIS Clearinghouse to make the data available for bulk and custom downloads from the NOAA Digital Coast Data Access Viewer. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process.
