Short summary
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 in the study area, while longer gaps reduce quality, especially over forests and steep terrain. The findings give insights on the data quality achievable by 1-day repeat-pass interferometry by Sentinel-1.
