TerraMesh
A planetary‑scale, multimodal analysis‑ready dataset for Earth‑Observation foundation models.
TerraMesh merges data from Sentinel‑1 SAR, Sentinel‑2 optical, Copernicus DEM, NDVI and land‑cover sources into more than 9 million co‑registered patches ready for large‑scale representation learning. Compared with earlier public corpora it offers >20× more pixel values and truly global, multi‑season coverage.
** Dataset release – End of June. **
