  15. What to talk about?

  16. GeoCAT - Kew Gardens, IUCN and ViBRANT Producing rapid species

    level conservation assessments

  22. None
  23. Red list assessments are dominated by Mammals, Amphibians, Birds, Corals

    And only ~ half include spatial component
  24. Geospatial aspects of the IUCN Process declining population small population

    size restricted geographic range
  25. controversial, but it is what we have. Area of Occurence

    - AOO Extent of Occurence - EOO Geospatial analysis
  26. EOO is a measure of the geographic range size of

    a species AOO is a measure of the area in which a species occurs
  27. Proprietary ESRI software Transformation of data before analysis No way

    to reconstruct the analysis that’s been done How the assessments have commonly been done
  28. Free and open-source software Easy to perform the specific AOO,

    EOO methods Make them accessible and shareable on the web But wouldn’t it be better if
  29. Introducing GeoCAT

  34. A GeoCat open-data format

  35. The .geocat file format json file that allows saving, reloading,

    and eventually replaying an entire assessment
  36. • Input data + omitted data • Data sources and

    metadata • Algorithm parameter settings • Application state • Analysis metadata
  37. Download Data

  40. Who is behind it? Join effort of ViBRANT, Kew Gardens

    and IUCN
  41. Global Forest Watch a work in development

  43. How can we rapidly detect global deforestion, process that data,

    and make it quickly and easily available to scientists, policy makers, journalists the challenge
  44. GFW is really problem of scale though how do we

    make it work on the web?
  45. 2,266,203 detected deforestation alerts at 500m currently covering 59 countries

    new data monthly As of September run
  46. global coverage 60m resolution new data every 16 days with

    a goal of
  47. None
  48. None
  49. None
  50. We let users interact with data layers, subscribe to location

    based alerts, and play data change over time, in the browser!
  51. We host and process the data with CartoDB. We generate

    a JSON file per tile containing the deforestation data codified in cells (each cell has a value for each time period - 15days). How we did it { time: 0.00576543211, rows: [ { upper_left_x: 16742472, upper_left_y: -2589569, time_series: [ 0, 8, 8, 8, 8, 12, 12, 12, 16, ...
