Always useful, even when the skies are overcast
Sentinel-1 is a two satellite, polar-orbiting RADAR constellation The radar collects data from Earth in all weather conditions, even through clouds. This data is suitable for monitoring the stability of infrastructures, among others.
Sentinel-1 achieves a resolution of 5 by 20 m, comparable to the surface area of a commercial warehouse.
Single Look Complex - SLC
- contains all data recorded by the radar (including distance and direction)
- basis for further data processing
Ground Range Data - GRD
- shows radar reflections in a map projection based on SLC data
- helps to distinguish differences in land cover
