• LICENSE.MD: dataset license file

Preview

The following figure presents a small preview of some selected images from the dataset. Due to different post-processing requirements, the Earth background only appears in some of the lightbox and synthetic images. Additionally, sunlamp images might include (parts of) the lightsource.
