RGB Global Dam Image Database V1

This database consists of two parts: the training set and the test set. Each image has dimensions of 512 × 512 pixels and a spatial resolution of 30 meters, covering approximately 15,360 × 15,360 square meters of ground area. Each image contains 3 spectral bands. The training set includes 6,062 samples, while the test set comprises 197 samples. Each sample consists of three images: a three-band image representing the period before the start of dam construction (with folder names ending in “A4”), a three-band image corresponding to the first reservoir impoundment (with folder names ending in “B4”), and a single-band image indicating the reservoir and dam crest geometry (with folder names ending in “mask”).
