A 30 m resolution Surface Water Map across China of 2015 (SWMC-2015) is released for free download.

Description

Surface waters account for a very small proportion of total water reserves and they are critical for supporting biodiversity, ecological security, drinking water, agricultural irrigation and industrial production. Multilayer perceptron (MLP) neural network was first introduced to produce a surface water map across China in 2015 (SWMC-2015).

The metadata information of SWMC-2015 is as follows:
