2013 LiDAR Survey, Colonial National Historical Park component of USGS Norfolk, VA LiDAR

LAZ files containing LiDAR point cloud data for Yorktown portion of Colonial National Historical Park. Subset of original data from USGS Norfolk, VA LiDAR project. The primary purpose of this project was to develop a consistent and accurate surface elevation dataset derived from high-accuracy Light Detection and Ranging (LiDAR) technology for the USGS Norfolk, Virginia Project Area. The LiDAR data were processed to a bare-earth digital terrain model (DTM). Detailed breaklines, 3D buildings, 2D buildings, forest polygons, tree points, bare-earth digital elevation models (DEMs), first return digital surface models, and last return digital surface models were produced for the project area. Deliverables were produced in both UTM and State Plane coordinates. Data was formatted according to tiles with each UTM tile covering an area of 1,500 meters by 1,500 meters and each State Plane tile covering an area of 5,000 feet by 5,000 feet. A total of 1,458 UTM tiles and 1,400 State Plane tiles were produced for the project encompassing an area of approximately 1,130 sq. miles.
