Drainage network extraction using LiDAR-derived DEM in volcanic plains.

A study used airborne light detection and ranging (LiDAR) to generate the high-accuracy and high-resolution digital elevation models (DEMs) that are a prerequisite to the automatic extraction of drainage networks over low-relief terrains. Drainage network extraction was performed on two sub-catchme...
