  1. Increasing Access to Satellite Data for ConservationThe Protected Area Archive Tool February 2005 Gary Geller Jet Propulsion Laboratory California Institute of Technology

  2. Background How can satellite images help conservation practitioners? • Observe: land cover, boundaries, threats… • Monitor change: in forest cover, land use… • Measure and map:areas and boundaries • Detect and map fires • Assess: for adaptive management • Predict:for proactive management • Communicate Data Access

  3. Example: Assess Encroachment Dong Hua Sao NBCA IUCN Cat VI Data Access

  4. Assess Encroachment 1975 Village Landsat image Data Access

  5. Assess Encroachment 1989 Village Landsat image Data Access

  6. Assess Encroachment 2000 Village Landsat image Data Access

  7. 1 km ASTER image 12 January 2002 Assess Encroachment Zoom Data Access

  8. Current Situation • NASA has been collecting conservation-useful satellite data since 1972 • Traditionally • Expensive • Geared towards science and research • Recent massive increase in data available • Cost no longer an issue • Loads of zero- and low-cost data available Data Access

  9. But There Are OBSTACLES… • Searching for and Ordering data • Using data Data Access

  10. Obstacles for Conservation Users • Too many sensors and products to choose from • Too many organizations offering data • Unfriendly search and order tools (EDG) • Contorted order processes (Glovis for ASTER L2) • Unfamiliar data formats (hdf) • Data complexity (multiband) • Expensive, sophisticated, and unfriendly tools (ENVI) • RS is a highly technical field • Internet access and bandwidth Data Access

  11. The Problem • To Summarize… • Data access and analysis systems are for experts • Result… • Many users are left out • Data are underutilized For land data Data Access

  12. Solutions Two solutions are possible: • Training • Make satellite data easier to • Obtain • Use Protected Area Archive Data Access

  13. Protected Area Archive • Creates collections of images on a particular theme • Packaged with tools to use them • Simple and intuitive • Audience: Users having no experience with RS • Requirements: No Internet or computer skills needed Sunderbans India and Bangladesh Data Access

  14. Demonstration Data Access

  15. Locator Map Data Access

  16. Collections Data Access

  17. Open Another Collection Data Access

  18. Zoom to Area of Interest Double click to open Data Access

  19. Scene Displays New scene displays Data Access

  20. Overlay Manager Click Overlay Manager Turn overlays on and off Add new overlays Data Access

  21. Measurement of Area and Distance Draw a polygon using the mouse… Get the area of the polygon Data Access

  22. Select Another Image Layer Data Access

  23. Change Analysis Data Access

  24. Annotate Image Data Access

  25. Status: Release • Version 1 completed in November • Released at IUCN World Conservation Congress • Working out plans for next release Bombetoka Bay Madagascar Data Access

  26. Status: Geographic Scope • Collections now available include • Cambodia • Thailand • Uganda • Sri Lanka • Mekong trace • Sunderbans • UNESCO sites • Birdlife International sites • New collections sometimes created on request (caveats) Data Access

  27. Plans: More Capabilities • More data layers (eg, MODIS) • More vector capabilities • Change analysis tools • Topographic layer, with draping capability • Mosaicking • Web-enabled • Web version Edgemont National Park New Zealand Data Access

  28. Plans: Big Picture • Formalized operations • Open source version • Collaborate with “on-the-ground” partners • Incorporate into training classes Garamba National Park, DRC Data Access

  29. Formalized Operations • Permanent operational home needed • New name, broad appeal • Website for users to order collections • Select specific ASTER images • Select Landsat path/rows and epochs • Generate collection • Stage via ftp, or mail CD/DVD Data Access

  30. Open Source Version • Eliminates DOC Export constraints • Eliminates CalTech licensing constraints • Brings in existing OS capabiliites • Enlists OS community resources • Allows user community to create custom versions • Port from ESRI MapObjectsLT to OpenEV Data Access
