2019 NOAA NGS Topobathy Lidar: Angelica to Dameron, MD

Published by National Geodetic Survey | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 02, 2026 at 04:54 PM | Dataset Last Updated: January 01, 2021 at 12:00 AM
The NOAA Chesapeake Bay MD1804 Option 1 West 4 Topobathymetric lidar data were collected by NV5 Geospatial, Inc. (NV5) using a Riegl VQ-880-GH system. The Chesapeake Bay MD1804 Option 1 West 4 acquisition spanned from 20190312-20190419 in 9 missions. The Chesapeake Bay MD1804 Option 1 West 4 dataset includes Topobathymetric data in LAS format 1.4, point data record format 6, with the following classifications in accordance with project specifications and the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards: 1 - unclassified 2 - ground 7 - noise 40 - bathymetric bottom or submerged topography 43 - submerged object 45 - water column 1 Overlap - edge clip This data set also includes lidar intensity values, number of returns, return number, time, and scan angle. The 100 meter buffered NOAA Chesapeake Bay MD1804 Option 1 West 4 project area covers approximately 492.737 square kilometers of an area encompassing a portion of the Chesapeake Bay and the nearby census designated places of Solomons, California, Hollywood, Lusby, Broomes Island, and St Leonard, Maryland. LAS files were compiled in 500 m x 500 m tiles. The NOAA Chesapeake Bay MD1804 Option 1 West 4 dataset is comprised of 2,593 - 500 m x 500 m LAS tiles.
