Description: These files contain contours at 2' interval for the York Coutny, VA project area. The project encompasses approximately 51, 943 acres (~81 sq. miles) area of the York County, Va. The project area has been subdivided to North ( 27 sq. miles) and South (54 sq. miles). LiDAR data is acquired using ATLM 3100 sensor for these two regions and classified as First return and bare-earth data. The files are created in LAS format in Virginia State plane, South zone, NAD1983 coordinate system with US_Survey feet units. The LiDAR used for the generation of Digital Elevation Model (DEM) and Digital Surface Model (DSM). The bare earth LiDAR data was supplemented with 3D breaklines to provide a solid and very accurate base to use during the contour generation at 2 foot interval.
