2019 NOAA NGS Topobathy Lidar DEM: Gwynn to Newport News, VA
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 final classified lidar data were then transformed from ellipsoid to geoidal height (Geoid12b) and used to create 53 - 5,000 m x 5,000 m topobathymetric DEMs in GeoTIFF format with 1m pixel resolution.
