  1. Satellite Remote Sensing for Environmental Advocacy Presented to Earthworks Washington, DC – March 26, 2004 John F. Amos, SkyTruth

  2. What Is SkyTruth? • A 501(c)(3) nonprofit organization • exemption in March 2002 • Based in Shepherdstown, West Virginia • A distributed network of remote sensing and GIS experts and partner organizations • Providing remote sensing and GIS assistance and training to environmental advocates and government agencies

  3. Sand waves, Bahamas

  4. Burning oil wells, Kuwait

  5. Owl Creek Mountains, Wyoming

  6. What Is Remote Sensing? • Collecting information from a distance, by measuring energy coming from the target • Energy reflected off the target from a natural source (sunlight) • Energy reflected off the target from an artificial source (examples: sonar, seismic, radar) • Energy emitted by the target (example: infrared “heat”)

  7. REFLECTED ENERGY, NATURAL SOURCEVisible – Infrared Image Landsat ETMsatellite image Northern California 180x180 km

  8. REFLECTED ENERGY, NATURAL SOURCE Visible – Infrared Image Aster satellite image US – Mexico border

  9. REFLECTED ENERGY, NATURAL SOURCE Visible – Infrared Image Probe airborne scanner image Santa Barbara, California

  10. REFLECTED ENERGY, ARTIFICIAL SOURCE Radar Image RADARSAT radar satellite image Natural oil slicks Gulf of Mexico

  11. EMITTED ENERGYThermal Image Landsat ETMthermal infrared satellite image Wildfire (yellow line) and burned area (dark red) Kazakhstan

  12. Trends in Remote Sensing Decreasing Data Cost Landsat, 1990s: $4,400 Landsat, today: $ 600 Desktop Mapping Improved GIS software Powerful desktop PCs Demonstrated applications Rapid Internet distribution New Platforms/Sensors High-resolution, Radar, Hyperspectral

  13. High-Resolution Imagery Ikonos high-resolution satellite image 1 meter detail (50 cm in 2004?) Precision mapping, monitoring
