Global Surface Water Mask

ຈັດພິມໂດຍ: Open Development Mekong

The 250m water mask product utilizes the SWBD (SRTM Water Body Data) and complement it with information from 250m MODIS data to create a complete representation of global surface water. The original intent of this product is not for hydrologic modeling, rather for masking water in products.
