Flooded Area

Live flood information - by city, by flood state (if required). Supports a /states endpoint which is non-geographic and simply gives the state of flooded areas as well as a geographic endpoint which will give flooded areas subject to a minimum_state or all areas together with their current flood status. In addition to topojson and geojson this endpoint supports the Common Alerting Protocol (CAP).

Note that flood states in CAP format have a default expiry time of 6 hours from the time that the API request is made.

Currently this data is only available for Jakarta.
