2019 NOAA NGS Topobathy Lidar: Gwynn to Newport News, VA

Description

The NOAA Chesapeake Bay VA1901 Option 3 West 1 Topobathymetric lidar data were collected by NV5 Geospatial, Inc. (NV5) using a Riegl VQ-880-GH system. The Chesapeake Bay VA1901 Option 3 West 1 acquisition spanned from 20190217-20190412 in 15 missions. The Chesapeake Bay VA1901 Option 3 West 1 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 feature 45 - water column 46 - overlap bathymetric bottom 71 - adjacent lift unclassified 72 - adjacent lift ground 85 - adjacent lift 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 VA1901 Option 3 West 1 project area covers approximately 964.624 square kilometers of an area encompassing a portion of the Chesapeake Bay and the nearby census designated places of Diggs, Matthews, Onemo, Susan, New Point, Seaford, Grafton, and Poquoson, Virginia. LAS files were compiled in 500 m x 500 m tiles. The NOAA Chesapeake Bay VA1901 Option 3 West 1 dataset is comprised of 4,821 - 500 m x 500 m LAS tiles.
