MULTIPLE ENDMEMBER SPECTRAL MIXTURE ANALYSIS OF DESIS IMAGE TO IDENTIFY ROOFTOPS IN KIGALI

The study examines how new satellite images can be used to create detailed maps of Earth’s surface height. Analysis of Sentinel-1C data shows that very short time gaps between images produce the most accurate results, while longer gaps reduce quality, especially over forests and steep terrain. The findings provide guidance for improving future mapping and environmental monitoring from space.
