Capella Space
Very high resolution 50 cm SAR satellite imagery, acquired worldwide with a revisit rate of 5 times a day. The collection contains data from 2020 to the present.
Overview
Capella Space imagery is acquired by seven very high and high resolution radar satellites on an intraday basis anywhere on the globe. The datasets are available starting from 2020. See more on the marketplace.
This collection provides the following processing levels:
- Single Look Complex (SLC)
- Geocoded Ellipsoid Corrected (GEC)
- Geocoded Terrain Corrected (GEO)
- Sensor Independent Complex Data (SICD)
Geographic coverage
The geographic coverage is global.
Geometry type
This collection accepts AOIs. You will get full scenes intersecting the defined AOI.
