Mapping Streams in High Resolution Using LiDAR Terrain Data
Authors: David Saavedra
Effective conservation planning depends on precise data. With the availability of high-resolution land cover data in the Chesapeake Bay watershed, the need for more accurate stream network data increases. Using LiDAR terrain data, direct detection methods are employed to extract channel networks from the landscape. Catchment- and regional-scale variables are incorporated to develop a stream mapping methodology that can be scaled and applied to the 64,000 square mile Chesapeake Bay watershed.
