On my way to #LPS25 and looking forward to one week of condensed #earthobservation! Our team will present a broad portfolio of tree species unmixing, sea ice, land surface phenology, and human-made material mapping. Also come and chat with me during the open science in the making session - #FORCE_EO

πŸ“£In our new paper we analyzed the impact of #Landsat and #Sentinel-2 πŸ›°οΈ #satellite data density and SMA endmembers on trends in #grasslands ground cover:
- for monthly composites data density is irrelevant
- correct endmember definitions are critical‼️

Sounds great! Do you know any package that works in a similar way, but post-processes along the temporary dimension?

A drone capture of a smallholder farming landscape. Overlaid are squares of the size of typical optical satellite missions. Openly accessible data (e.g. Landsat or Sentinel-2) is often not sufficient to capture the landscape complexity in full detail, for example when trying to delineate individual fields. Here, one Landsat pixel contains fractions of multiple fields. Commercial data come at higher spatial resolution, offering potential to discriminate indivudual landscape components.

I'm so happy and proud of this decision πŸ™‚. It is very important now to use the data, and compare the performances obtained with 2 and 3 satellites in your future communications. It will be the good way to thank @esa.int and #Copernicus.
