Guest lecture for CCNY GIS

Description of GeoCAT, GFW, and CartoDB

Transcript

1. Geospatial data on the web. Open, simple, and beautiful.

15. What to talk about?
16. GeoCAT - Kew Gardens, IUCN and ViBRANT Producing rapid species level conservation assessments
17. http://rlat.kew.org/
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
31. http://rlat.kew.org/
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
42. http://vizzuality.com/projects/gfwprototype
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
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, ...
52. Onward, to CartoDB (http://cartodb.com) geospatial database on the cloud
57. CartoDB Dashboard
58. CSV KML XLS OSM TIFF SHP JSON WKT GML GPS
59. Drag + Drop = Table, Maps, APIS sooooo simple
66. Sharing your work via links, embeds, apis using integrated caching to fly
68. Build it into your applications with client libs Libraries for Javascript and many other languages
72. We are also using CartoDB to push the limits of online mapping temporal maps, smart indexing, distributed caching, pl/R services
