Evaluating Environmental Quality Using Spatial Data Derived from Satellite Imagery

Abstract:Spatially explicit identification of status and changes in environmental conditions over large, regional areas is key to targeting and prioritizing areas for potential further study and environmental protection and restoration. A critical limitation to this point has been our ability to integrate field-based measures of environmental conditions, such as those being collected by the Environmental Monitoring and Assessment Program (EMAP), with spatially continuous landscape and biophysical data. Relatively new spatial data derived from satellite imagery and other sources, the development of statistical approaches and models, and geographic information systems make it possible to evaluate environmental quality at multiple scales over broad geographic regions. This presentation describes and demonstrates the use of spatial data derived from remote sensing imagery, especially the National Land Cover Database (NLCD), in conducting environmental assessments.

Although this work was reviewed by EPA and approved for publication, it may not necessarily reflect official Agency policy.
