GFM-Bench/SSL4EO-L-Benchmark

NLCD-L

This dataset incorporates both SSL4EO-L Benchmark dataset and the NLCD-L dataset which is derived from the original SSL4EO-L Benchmark dataset by combining optical data from Landsat-7 and Landsat 8-9 with NLCD ground-truth labels, originally proposed in SSL4EO-L. The dataset contains 20 MSI bands, deliberately exceeding Sentinel-2’s channel count. It comprises 17,500 training samples, 3,750 validation samples, and 3,750 test samples.

Please refer to the original SSL4EO-L paper for more detailed information about the original SSL4EO-L Benchmark dataset:
