These Lidar data were collected over the Dry Tortugas National Park in 2015 by the NOAA/NGS Remote Sensing Division. The data are intended to serve a broad spectrum of coastal management needs by surveying submerged topography for the purposes of habitat mapping, ecological monitoring, change detection, and event assessment (e.g., hurricanes and extreme storm events).
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. 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 20150314 - 20150323. 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. This data set may also include lidar intensity values and encoded RGB image values.
