FBIS-22M

Field Boundary Instance Segmentation - 22M dataset (FBIS-22M) - large-scale, multi-resolution dataset comprising 672,909 high-resolution satellite image patches (0.25 m – 10 m) and 22,926,427 instance masks of individual fields.
Note: We have excluded images from the Pleiades satellite mission due to third-party usage policies. This does not impact the dataset’s coverage or quality.
