254 Closest Health FacilityFx

I was invited last month for a KODI (Kenya Open Data Initiative) for a developers workshop basically learning how to use the API rather than downloading data , and honestly my hard disk was getting crammed with csv,tsv,xml,xlsx  "OMG".

One thing that caught my attention was the Geo spatial queries and i had  a some questions in mind e.g "what  health facility is near me at a given radius ? and e.g how long will it take from a dispensary to a health center ?".

API used.

JavaFx    - UI
Routing  -  Graphhopper API  (key)
Map       -  NASA WorldWind Java (offline mode)
Data       -  Kenya Open Data API (key)

Any point you click in the map within the Kenya boundary ,you get health facilities within the given radius,by default is 500 m,and the county map and name displays in the county pane.
A red border means no facilities within that radius,and green vice versa.

Click a health facility to add to the route pane.which returns distance in kilometers and time in minutes.
