PPT-Characterizing patchy soil and bedrock cover is useful for hydrology, ecology, and geomorphology

Airborne lidar is addressing the need however N ew algorithms are need that account for both slope and roughness Better accuracy assessment is needed to constrain which landscapes are best suited for specific classifiers.
