2015 NOAA NGS Topobathy Lidar DEM: Buzzards Bay Block3 (MA)

These data were collected and derived by the National Oceanic Atmospheric Administration, National Geodetic Survey (NGS) Remote Sensing Division using a Riegl VQ820G system. The data were acquired from 20151109 - 20151123. The data includes topobathy data in an ERDAS Imagine (IMG) format and a 1 m grid size. The DEM data includes utilization of ground (2), bathymetric point (26), submerged object (29), and International Hydrographic Organization (IHO) S-57 object (30) classification fields from LAS files. An automated ground classification algorithm was used to determine bare earth point classification. It should be noted that not all returns may be correctly classified; therefore the user should examine for acceptability. In addition to the DEMs, the topobathy lidar point data are also available.
