Class 2 (ground) lidar points in conjunction with the hydro breaklines were used to create a 1 meter hydro-flattened Raster DEM. Original Dataset Geographic Extent: Block 1: Niagara, Putnam and Westchester Counties covering approximately 1,367 square miles. Block 2: Lewis, Oneida, Herkimer, Fulton, and Montgomery Counties covering approximately 2,396 square miles. Block 3: Monroe, Ontario, Steuben, Onondaga, Cortland, Chenango, and Madison Counties covering approximately 2,806 square miles. Block 4: Albany, Greene, Hamilton and Schenectady Counties covering approximately 3,167 square miles. Block 5: Broome, Chemung, Chenango, Cortland, Delaware, Ontario, Otsego, Schuyler, Steuben, Sullivan, Tioga, Yates Counties covering approximately 6,198 square miles. Original Dataset Description: NY_FEMAR2_Central_2018_D19 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 individual 1000 m x 1000 m tiles as tiled bare earth DEMs; all tiled to the same 1000 m x 1000 m schema. Original Dataset Ground Conditions: Lidar was collected in early 2019 through mid 2020, while no snow was on the ground and rivers were at or below normal levels. This metadata record supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV). For this data set, the DAV is leveraging the GeoTIFF files hosted by USGS on Amazon Web Services.
