COP-GEN-Benchmark

Evaluation dataset for the COP-GEN paper (arXiv:2603.03239). Enables stochastic-benchmark evaluation of generative EO models by comparing generated sample sets against real multi-temporal Sentinel-2 observations at 495 geographically diverse locations.

Three parallel subsets with identical schema and shared georeferencing (same Major TOM v2 1056x1056 grid):
