MESPOM Introduction to Spatial Analysis with GIS Course Project

  1. 1. Potential MPAs for Sea Turtleand Coral Reef Conservation in Indonesia Introduction to Spatial Analysis with GIS Course Project By: Nara Wisesa
  2. 2. Background• Idea – To find potential MPA sites in Indonesia for: • Coral reefs • Or Sea turtle breeding area • Or both at the same time
  3. 3. Finding Suitable Data• Find data for global coastline (http://www.ngdc.noaa.gov)
  4. 4. Finding Suitable Data • Data for Existing MPAs – World Database on Protected Areas (http://www.wdpa.org) – Managed to find polygon of existing MPAs • Google Map KMZ files, need to be extracted and converted into KML
  5. 5. Finding Suitable Data • Data for Coral Reefs in Indonesia – Reef Base (http://www.reefbase.org) – Managed to find datasheet of coral reef sites • However, it is a point-data, not a polygon • Therefore, a 2 km buffer would be used around each point to approximate extent of reefs • Data for Indonesian coastline – Coral Reef data also provides coastline data of Indonesia • Possible to create coastal buffer
  6. 6. Finding Suitable Data • Data for Sea Turtle breeding sites in Indonesia – OBIS SeaMap (http://seamap.env.duke.edu) – Could not find data on exact locations – Managed to find satellite tag data on sea turtle migration routes – used as proxy • Breeding sites would be approximated as areas where migration routes intersects with the coastline buffer zone • Also Google Map KMZ files, need to be extracted and converted
  7. 7. Putting Things Together• Add Coastline data
  8. 8. Putting Things Together• Add Coastline data• Import KML file of existing MPAs and turtle migration routes – Merge MPAs into one data layer – Merge turtle routes into three data layers, separated by species
  9. 9. Putting Things Together• Add Global Coastline data• Import KML file of existing MPAs and turtle migration routes• Add Coral Reef and Indonesian Coastline data
  10. 10. Putting Things Together• Add Global Coastline data• Import KML file of existing MPAs and turtle migration routes• Add Coral Reef and Indonesian Coastline data• Add map of countries and ocean
  11. 11. Data Analysis• Create Buffers for: – Coastline (potential MPAs should be within 2 km from the coastline) – Coral reef sites (reef areas are approximated to extend for 2 km around each site) – Turtle migration routes (turtles approximately spread 1 km around their migration routes)
  12. 12. Data Analysis• Perform Map Analysis – On coastline buffers and reef buffers to calculate potential MPA for coral reefs – On coastline buffers and turtle route buffers to calculate potential MPA for turtle nests – On coastline buffers reef buffers and turtle route buffers to calculate potential MPA that would protect both
  13. 13. Products• Potential MPA for Coral Reef• Potential MPA for Sea Turtle Nests• Potential MPA that protects both
  14. 14. Products• Map of potential MPAs all over Indonesia – Hard to comprehend, scale too big• Focus on Potential MPAs that protect both – Only found in Bali
  15. 15. Final Product
  16. 16. thank you!For protecting me!! :) Questions?
