2016 NOAA NGS Topobathy Lidar DEM: Key West (FL)

These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ820G system. The data were acquired from 20160419 - 20160425. The data includes topobathy data in an LAS 1.2 format file classified as 1 - unclassified, 2 - ground, 7 - topo noise, 26 - bathymetric bottom or submerged topography, 27 - water surface, 28 - submerged object and 30 - International Hydrographic Organization (IHO) S-57 objects. A digital elevation model was then derived from the lidar points.
