MOD44W.005 Land Water Mask Derived From MODIS and SRTM

AI-generated Key Takeaways

• The MODIS/MOD44W/MOD44W_005_2000_02_24 dataset provides a global water mask at 250m resolution, combining data from SRTM and MODIS to identify surface water.

• This dataset, covering circa 2000-2002, is primarily used for processing raster data and masking out water in final products.

• It includes two bands: water_mask (indicating land or water) and water_mask_qa (specifying the water pixel's source).

• MODIS data and products acquired through the LP DAAC have no restrictions on subsequent use, sale, or redistribution.

• Users can explore and analyze this dataset further using Google Earth Engine.

Description

The Global Water Mask uses the SWBD (SRTM Water Body Data) in combination with MODIS 250m data to create a complete global map of surface water at 250m spatial resolution, circa 2000-2002. This dataset is intended for use in processing of raster data and for masking out water in final raster data products.
