资源简介:

2 foot contour lines in Chesapeake, VA. Contours were generated from a regional bare earth DEM from the USGS resampled from 2ft grids to 20ft grids, using the nearest resampling method. The resampling allows for smoother, more cartographic contours. The DEM was hydro-flattened and reviewed at 1:5000. Elevations are in NAVD88(feet). Contours generated that measured less than 100 in the Shape_Length field were removed. Elevations are based on a "bare-earth." Data is for reference only.
