Overview

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.
