isochrone service #861

Closed abyrd closed 10 years ago

abyrd commented 11 years ago

Users often just want classic, evenly-spaced or single vector isochrones around an origin point rather than rasters of a full travel time surface. Isochrones should be provided in vector format by a separate API call.

clearly we can apply a time cutoff to the search based on the highest isochrone value. the quick and dirty implementation is to just do a search with a time cutoff and build a hull around the entire SPT.

This has been implemented in several different forms now.
