415 square miles Hydro-Enforcement / Flattening and 1 ft Contours (QL1 LiDAR)
In 2017, Kinetics Geospatial produced a hydro-enforced / flattened DEM for Anne Arundel County, Maryland. Specifications included collection and enforcement / flattening of rivers and streams over 5 ft wide, and lakes and ponds larger than 0.5 acre with connectors collected through culverts. Single line streams were compiled for streams less than 5ft. Topologically correct 1 ft contours were produced from the hydro-enforced / flattened surface model.
