Core principles

The Tygron Platform allows for Projects to be used as Templates. Applying them to a new location, carrying over their calculation models and configurations, means its possible to rapidly apply identical analyses. Using the API, this process can be fully automated.


Authentication

Every API call must be accompanied with an appropriate form of authentication

URL starts with Description Example
/api/ HTTP Basic Authentication Header "Authorization: Basic "+base64encode("user@example.com:password")
/api/session/ Any url starting with /api/session/ "/api/session/items/neighborhoods?f=JSON&token=[...]"
/web/ Web token or API token query parameter in url "/api/web/2dmap.html?f=JSON&token=[...]"


Applying a Template project

To use a template named "demo heat stress" to create a new Project named "my_project", and get its API token for further operations:

Method Parameters Response
POST /api/io/start/?f=JSON ["EDITOR", "demo_heat_stress"] sessionId
POST /api/io/save_project_as/?f=JSON [sessionId, "","my_project",false] Whether succesful
POST /api/io/join/?f=JSON [sessionId, "EDITOR"] json, including apiToken


Generate on new location

Set new Project to a 2km by km map size, and its location to latitude 52.080617, longitude 4.312135 (in coordinate system EPSG:4326 ):

Method URL Parameters Response
POST api/session/event/editor/clear_map/?f=JSON [true] n/a
POST /api/session/event/editor/set_initial_map_size/?f=JSON [2000,2000] n/a
POST api/session/event/editor/start_map_creation?f=JSON&crs=4326 [52.080617, 4.312135, false, []] n/a
GET /api/session/info/?f=JSON json, including state.
"NORMAL" means
generation is done
Notes

  • Any Project can be used as a Template, as long as there is no currently running Session, or the Project is set to read-only.
  • All coordinates are x:y, or longitude:latitute. This also includes coordinates in MultiPolygons.
  • To add an Area of Interest, in the "start_map_creation" event replace the empty array with an array of MultiPolygons.
