Environment Rs August 08

  1. 1. Environment through Remote Sensing
  2. 2. Environmental Changes: <ul><li>Inherent type : seasonal & other natural changes including the changes caused by natural disasters – positive or negative </li></ul><ul><li>Induced type: due to human use and abuse – negative only </li></ul>
  3. 3. Environmental Changes: <ul><li>Local: </li></ul><ul><li> village, district level </li></ul><ul><li>Regional: </li></ul><ul><li>state, national level </li></ul><ul><li>Global: </li></ul><ul><li>continental, world level </li></ul>
  4. 4. Our concern is to: <ul><li>Map, Measure and Monitor </li></ul><ul><li>> the natural & man-made world; </li></ul><ul><li>> locally, regionally and globally </li></ul><ul><li>on a periodical & real-time basis </li></ul>
  5. 5. Global Monitoring <ul><li>Environmental features monitored include : </li></ul><ul><li>Global vegetation cover </li></ul><ul><li>Ocean productivity </li></ul><ul><li>Global biosphere </li></ul><ul><li>Ocean Temperature </li></ul><ul><li>Ozone levels </li></ul><ul><li>Snow and ice </li></ul><ul><li>Atmospheric pollutants </li></ul><ul><li>Wave height and direction </li></ul>
  6. 6. Ozone Levels <ul><li>Depletion develops in October </li></ul><ul><li>Changes seasonally </li></ul><ul><li>Gradually getting larger over time </li></ul>
  7. 7. Global Vegetation Cover
  8. 8. Ocean Temperature <ul><li>Water is a good approximation of a black body </li></ul><ul><li>Monitoring climatic events, eg. El Nino </li></ul><ul><li>Monitor long term climatic change </li></ul>
  9. 11. Remote Sensing Applications Mineral and Rock Spectral Mapping
  10. 18. data model
  11. 34. Local Environmental Monitoring De-forestation
  12. 37. <ul><li>Bush Fire - Detection using smoke </li></ul>
  13. 38. <ul><li>Bush Fire - Detection using smoke </li></ul>
  14. 39. Remote sensing platforms: LIDAR <ul><li>Canopy surface </li></ul>
  15. 40. Remote sensing platforms: SAR (Synthetic Aperture Radar) <ul><li>SAR image of Washington, DC </li></ul><ul><li>textures are easily differentiated_ </li></ul>
  16. 41. Remote sensing platforms: SAR (Synthetic Aperture Radar) <ul><li>SAR image of Amazon Basin </li></ul><ul><li>previous river channels clearly visible </li></ul>
