Today we release a prototype of COP-GEN - a universal generative model for Copernicus data. ๐๐๐-๐๐๐-๐๐๐ญ๐ is a model trained globally on the thumbnails of the Major TOM Core datasets, including Sentinel-2 L1C, Sentinel-2 L2A, Sentinel-1 RTC, and COP-DEM GLO-30.

How is it universal? COP-GEN learns a joint generative process of all modalities, which means that it can reconstruct data from any subset of present observations. ๐๐ข๐ญ๐ก๐จ๐ฎ๐ญ ๐ญ๐ซ๐๐ข๐ง๐ข๐ง๐ ๐ฌ๐ฉ๐๐๐ข๐๐ข๐๐๐ฅ๐ฅ๐ฒ to perform any of these tasks it can be used to approximate:
โ
Sentinel-1 to Sentinel-2 translation
โ
Elevation estimation from Sentinel-2 or Sentinel-1
โ
Atmospheric Correction (L1C to L2A pipeline)
โ
Atmospheric Generation (L2A to L1C)
โ
...and any other task involving translation between the supported modalities
On its own, the model can be used as a useful prior for estimating the data likelihood distribution for Copernicus data. COP-GEN-Beta learns joint, conditional, and marginal distributions within a single unified backbone, allowing to flexibly sample any modality given any condition.
Why is it Beta? Because thumbnails are a low-cost representation of the data that scales well and we managed to develop this prototype quite fast. We are currently developing the more costly COP-GEN model that supports the original data. For now, we wanted to showcase the prototype and make it available to the community for a test!
