    • 2017 NOAA NGS Topobathy Lidar DEM: Florida Keys Outer Reef, Block 04

    Metadata Updated: October 31, 2024

    These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ880G system. The data were acquired from 20170216 - 20170220. The data includes topobathy data in an LAS 1.2 format file classified as unclassified (1), ground (2), noise (7), bathymetric point (26), submerged object (29), and International Hydrographic Organization (IHO) S-57 object (30) in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. This data set may also include lidar intensity values and encoded RGB image values. The DEM was created from the bathymetric points (class 26) using las2dem from LAStools and GDAL.
