Services to EPA staff include comprehensive analysis of these data, which is commonly used in support of air quality, water quality and land remediation programs. Specifically, RSIAS provides EPA with a broad set of remote sensing services, including:

  • data collection
  • processing
  • interpretation
  • digital analysis
  • technical consulting
  • reporting

RSIAS services help EPA make better decisions, including in hazardous waste site evaluation. The results can speed the process of remediation at Superfund and Brownfields sites, by allowing EPA to determine the exact location and extent of areas of interest.
