  1. 1. Measuring Canopy Dynamics in a Savanna Woodland using Automatic Digital Cameras Stefan W Maier Research Institute for the Environment and Livelihoods School of Environment Charles Darwin University, Darwin, Australia
  2. 2. 1.5h drive south of Darwin Litchfield National Park: 1,461km2 conservation reserve monsoonal north of the Northern Territory annual rainfall ~1420mm (~90% December - March) Eucalypt open forest / woodland (E. miniata + E. tetrodonta) LTERN long term fire plots CDU leaf traps AusCover cal/val site (5x5km2 homogeneous area) OzFlux flux tower (2014) CDU tower based spectroradiometers (2014) Savanna Supersite Litchfield National Park - Location
  3. 3. Savanna Supersite Litchfield National Park - Vegetation
  4. 4. Savanna Supersite Litchfield National Park - Fire
  5. 5. Savanna Supersite Litchfield National Park - Post-Fire
  6. 6. Savanna Supersite Litchfield National Park - Leaf Fall
  7. 7. Savanna Supersite Litchfield National Park - Fire Damage
  8. 8. Savanna Supersite Litchfield National Park - Access Issues
  9. 9. Camera Setup 2 Wingscapes TimeLapse cameras 5M pixels 4 AA batteries → approx. 6 months 8GB SD card horizontal + magic angle (57.5⁰) photo every 30 min
  10. 10. Canopy Camera 2013/02/06 2013/08/01
  11. 11. Analysis Canopy Camera Object Oriented Classification (eCognition) fully automatic
  12. 12. Canopy Dynamics fire
  13. 13. Canopy Dynamics fire
  14. 14. Canopy Dynamics fire
  15. 15. Next Generation Camera android smartphone + python script + scheduler app 10W solar panel + SLA battery communication via 3G or WiFi build-in power saving “intelligence”
  16. 16. Conclusion Wingscapes TimeLapse cameras are easy to set up
  17. 17. Conclusion Wingscapes TimeLapse cameras are easy to set up frequent image capture makes automatic analysis easier
  18. 18. Conclusion Wingscapes TimeLapse cameras are easy to set up frequent image capture makes automatic analysis easier off-line modus → no system health monitoring, data loss
  19. 19. Conclusion Wingscapes TimeLapse cameras are easy to set up frequent image capture makes automatic analysis easier off-line modus → no system health monitoring, data loss automatic analysis requires refinement
  20. 20. Conclusion Wingscapes TimeLapse cameras are easy to set up frequent image capture makes automatic analysis easier off-line modus → no system health monitoring, data loss automatic analysis requires refinement smartphone camera: cheap, “intelligent”, includes comms
