Landsat Level-3 Dynamic Surface Water Extent (DSWE) Science Products provide information that represents surface water inundation as detected in cloud-, shadow-, and snow-free pixels, in six acquisition-based raster files.

Return to Landsat Science Products Overview

 

Landsat DSWE products provide important information about the existence and condition of surface water. 

The table below displays how different communities use Landsat DSWE products in their research. 

Community Potential use
Hydrologic science/ Water resource management Hydrologic modeling (local to national scale), Large river discharge estimation, local level surface storage reservoir monitoring
Biologic science/Resource management Habitat assessment, minimum flow requirement analyses
Wetland science/Resource management  Wetland delineation and monitoring
Climate science/Change response Energy balance and carbon cycling studies and modeling
Emergency preparedness and response Flood mitigation and recovery, aid distribution, insurance underwriting; drought monitoring
Geospatial data providers Land cover and cartographic data enhancement
State and local government Storm water best management practices, pond and reservoir monitoring

The images and animations below are examples of how Landsat DSWE data are used.
