NASA's ASTER Global Water Bodies Database (ASTWBD) Version 1 provides a global inventory of water bodies larger than 0.2 square kilometers at 30-meter resolution, paired with elevation information. The dataset was created by the Sensor Information Laboratory Corporation (SILC) using ASTER imagery collected between March 2000 and November 2013 to correct water surface elevations in the corresponding digital elevation model. It classifies features into ocean, lake, or river categories, with manual corrections applied for sea ice and river delineation.
