Middle East AOI

Randomly sampled 5000 data tiles (3000 for training, and 1000 for validation and testing). Occasionally, not all tiles were available for all datasets. We include a detailed breakdown of the number of chips per dataset below.

Datakind	Chips
`s1grd-2020`	5000
`gssic`	4829
`gunw_2020-04-01_2020-06-30`	4641
`gunw_2020-01-01_2020-03-31`	4561
`s2rgbm-2020`	5000
`biomass-2020`	5000
`esaworldcover-2020`	5000
`modis44b006veg`	5000
`ghsbuilts-2020`	5000
`srtmdem`	5000

We provide '.csv' files with predefined train (blue), test (orange) and validation (green) splits that can be used for repeatability and comparability of experiments. 60% of tiles are allocated for training, 20% for validation, and 20% for testing.
