How do I calculate drive time catchment ISOCHRONES using OSM data. Thanks. Sam |
You can take a look at OpenRouteService which has a Accessibility Analysis. But keep in mind that their routing data is currently very outdated (from 2012-10-29). Another reachability analysis is available from Geofabrik. And we even have a whole wiki page about Isochrone (you didn't search for it, did you?). Thanks Scai, I looked at the page however there were only three software references available. Mainly looking for a free software/service to which a request can be sent a response recd. in the form of isochrone. Accessibility Analysis seems the best, but I have had a number of attempts for a reasonably long period of wait for 3 or 5 minute time without much luck.
