Spatially- and temporally-aligned visible (optical) ↔ SAR satellite image patches
for cross-modal representation learning (CLIP-style SAR↔visible alignment).
~3.68M paired patches (this is a snapshot of an in-progress 10M build).
shards/ — WebDataset .tar shards. Each sample key K has three members:
K.vis.npy — visible/optical, uint8 [3, 224, 224] (3 bands)
K.sar.npy — SAR, uint8 [2, 224, 224] (VV, VH)
K.json — per-sample… See the full description on the dataset page:
