Data Fusion

How does revisit affect data fusion methods (between S2 and a potential VHR constellation)

In a previous post, we showed that spatio-temporal fusion methods would enable to obtain hybrid data with the revisit of the S2-NG mission (3 to 5 days), and the resolution of the Sentinel-HR mission (2 m), with an uncertainty better than the atmospheric correction errors (better than 0.01 in reflectance).  In this section, we tested […]

Test of spatio-temporal fusion of Sentinel-2 New Generation data with a potential VHR mission

Three years ago, we started the phase-0 study of a mission named Sentinel-HR : S-HR would be a satellite mission to complement Sentinel-2 new generation (S2-NG) with In that study, one of our assumptions was that a lower revisit frequency than that of Sentinel-2 was sufficient. This seems possible because, in most cases, the high frequency […]
