Global Surface Water Mask

បោះពុម្ពផ្សាយដោយ៖ 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.
