This study demonstrates how to use KOMPSAT-3A stereo data to extract digital surface models (DSM). The study area is the Bingham Canyon Mine in Utah, USA. The mine is the largest man-made excavation in the world and is considered to have produced more copper than any other mine in history.

Dr. Philip Cheng, a senior scientist at PCI Geomatics conducted this study with KOMPSAT-3A data and provided results to SI Imaging Services(SIIS).

SIIS provided a level 1O single-pass stereo pair of KOMPSAT-3A data acquired on Sept 25, 2019 with acquisition angles of +/- 24 degrees to PCI Geomatics. Level 1O is a processing level so-called ortho ready. It is the product corrected for geometric distortions and projected to UTM.
