2015 USGS Lidar: Eastern Shore VA va2015_eastern_shore_m8445_metadata eng Dataset EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION elevation Bare earth 2015 April Continent>North America>United States>Virginia Leading Edge Geomatics (LEG) collected 994 square miles in the Virginia counties of Accomack and Northampton. The nominal pulse spacing for this project was 1 point every 0.7 meters. Dewberry used proprietary procedures to classify the LAS according to project specifications: 0-Never Classified, 1-Unclassified, 2-Ground (bare earth points identified as Model Key Points are flagged with the Model Key Point bit), 7-Low Noise, 9-Water, 10-Ignored Ground due to breakline proximity, 17- Bridge Decks, 18-High Noise. Because the Eastern Shore Virginia LiDAR project includes data from the Sandy Topobathy project, there are also topobathy point classifications. They are: 23 - Sensor noise, 24 - Refracted sensor noise, 25 - Water column, 26 - Bathymetric bottom, 27 - Water Surface. Classes 28, 29, and 151 were also included, but after discussion with Dewberry, were determined to be noise classes that should be disregarded. NOAA Office for Coastal Management processed all classifications of points to the Digital Coast Data Access Viewer (DAV), but have made the topobathy noise points unavailable. Classes available from the DAV are: 1, 2, 7, 9, 10, 17, 18, 25, 26, 27. Dewberry produced 3D breaklines and combined these with the final LiDAR data to produce seamless hydro flattened DEMs for the project area. The data was formatted according to the VBMP tile naming convention with each tile covering an area of 5,000 feet by 5,000 ft. A total of 1375 LAS tiles and 1310 DEM tiles were produced for the entire project. The NOAA Office for Coastal Management (OCM) downloaded this lidar data from the USGS site: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/NED/LPC/projects/USGS_LPC_VA_Eastern_ShoreBAA_2015_LAS_2017/ and processed the data to be available on the Digital Coast Data Access Viewer (DAV). In addition to these lidar point data, the breakline data are also available. These data are are available for download at the link provided in the URL section of this metadata record.
