The Landsat Level-3 Dynamic Surface Water Extent (DSWE) Science Product provides information that represents surface water inundation as detected in cloud-, shadow-, and snow-free pixels, in six acquisition-based raster files.
The Landsat DSWE product provides important information about the existence and condition of surface water.
The table below displays how different communities use Landsat DSWE products in their research.
|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.
The Landsat Collection 2 Level-3 Dynamic Surface Water Extent science product provides raster data that represent surface water inundation per pixel in Landsat 4–8 imagery. The Collection 2 Dynamic Surface Water Extent science product contains six acquisition-based raster products relating to surface water. Surface water extent is modulated by weather and climate, stream network hydrology, and geo
