so2sat

So2Sat LCZ42 is a dataset consisting of co-registered synthetic aperture radar and multispectral optical image patches acquired by the Sentinel-1 and Sentinel-2 remote sensing satellites, and the corresponding local climate zones (LCZ) label. The dataset is distributed over 42 cities across different continents and cultural regions of the world.

The full dataset (all) consists of 8 Sentinel-1 and 10 Sentinel-2 channels. Alternatively, one can select the rgb subset, which contains only the optical frequency bands of Sentinel-2, rescaled and encoded as JPEG.

so2sat is configured with tfds.image.so2sat.So2satConfig and has the following configurations predefined (defaults to the first one):

  • rgb (v0.0.1) (Size: ?? GiB): Sentinel-2 RGB channels

  • all (v0.0.1) (Size: ?? GiB): 8 Sentinel-1 and 10 Sentinel-2 channels
