Dataset Information

This dataset contains the geomorphology of a ~70 km long section of the fault geomorphology near Sabzevar in the NE Iran. The point cloud datasets were derived via the rational function model (RFM) with the Leica Photogrammetry Suite (LPS) built in ERDAS Imagine from data acquired by SPOT-6 tri-stereo optical satellite imagery.
