  1. Landsat ETM+ scan line corrector (SLC) – failed May 31 2003http://landsat.usgs.gov/products_slc_off_data_information.php SLC compensates for forward motion of the scanner during scan

  4. MODIS ASTER (TIR) ASTER (SWIR) ASTER (VNIR) MISR MOPITT CERES Terra Satellite Terra is the flagship of NASA's Earth Science Enterprise. ASTER is the ‘zoom lens’ of Terra..

  6. Growth of Riyadh, Saudi Arabia

  7. In mid-April 2000, the Terra spacecraft was turned upside down and pointed at the Moon. This ASTER image was acquired at that time, showing band 3 visible in black and white.

  8. ASTER Bands (versus Landsat TM)

  9. ASTER bands – band 3 has two modes: 3N and 3B

  10. ASTER bands versus Landsat ETM+ 60 km swath, 16 day repeat cyle

  11. Visible-NIR Visible-NIR Short Wave IR Thermal IR

  12. August ’03 Montana Forest Fire ASTER 3-2-1 RGB composite 5 km Normalized Difference Burn Ratio, developed for TM, applied to ASTER bands 4 & 6 Burn Ratio (TM4-TM7)/(TM4+TM7)

  14. SWIR classified band composite

  15. ASTER Response to Indian Ocean Tsunami Banda Aceh before tsunami (left) and 5 days after tsunami (right)

  16. ASTER Response to Indian Ocean Tsunami Phuket, Thailand before tsunami (left), 5 days after tsunami (center), and merged with SRTM data of 10m elevation

  17. ASTER – imagery and DEMs 2000- Global DEM to 83 degrees latitude Sample ASTER draped image

  18. ASTER data comes in three packages for VNIR, SWIR, TIR This fly combines the DEM only with VNIRhttp://visibleearth.nasa.gov/view_rec.php?id=170successful merge of VNIR/ SWIR? + DEM or different combohttp://asterweb.jpl.nasa.gov/gallery-detail.asp?name=FogoL1A product -> misregistration of VNIR and SWIR, solved with L1B

  19. Longyearbyen, Svalbard,Norway The perspective view was created by draping a simulated natural color image over an ASTER-derived digital elevation model. The image was acquired July 12, 2003, and is located at 78.2 degrees north latitude, 15.6 degrees east longitude. Longyearbyen is the world’s northernmost town

  21. www.mapplace.ca - BC Ministry of Energy, Mines and Petroleum Resources 100 anaglyph scene images created and available online

  22. North Coast Mountains, BC N The vertical image (bands 1,2,3) was orthorectified and coloured. The 3B image was left grey and was not orthorectified. When combined into the anaglyph image we manually adjusted them to get a reasonable relief. Colours were designed to maximise geological contrasts.

  26. Chapman Glacier, Canadahttp://asterweb.jpl.nasa.gov/gallery-detail.asp?name=Chapman

  27. GLIMS: Global Land Ice Measurements from Space • Goal is to determine the extent of world’s glaciers and the rate at which they are changing. • Acquire global set of ASTER images • Map global extent of land ice • Analyze interannual changes in length, area, surface flow fields • Over 60 institutions participating

  28. Monitoring changes in glaciers and glacier lakes Tibet Himalaya Bhutan Himalaya Image is a portion of an uncalibrated ASTER Level 1A VNIR false-color image (321RGB), acquired on November 20, 2001

  29. Monitoring Supraglacial and ProglacialLakes Lugge Tsho Thorthomi Tsho Raphsthreng Tsho N 2 kilometers The stagnating termini of glaciers in the Bhutan Himalaya. Glacial lakes have been rapidly forming on the surfaces of debris-covered glaciers worldwide during the last few decades. Image is a portion of an uncalibrated ASTER Level 1A VNIR false-color image (321RGB), acquired on November 20, 2001

  30. Tsho Rolpa, Nepal • Quickly forming supragla- cial lake with natural dam at glacier’s unstable terminal moraine. • Mitigation plans developed • in years before disaster was imminent. • Emergency drainage con-duit constructed just in time to circumvent disaster.
