There is a product from Mapzen that I have never seen anywhere else : Isochrones (https://mapzen.com/documentation/mobility/isochrone/api-refe...). Been interested in this for years (https://stackoverflow.com/questions/9403699/map-of-all-point...) They were the only ones to provide a solution.

I am super sad to see this go and still haven't seen any alternative.

Happy to hear about anything in this direction :s.




Ahem:

- GRASS has had that since the 80s: https://grass.osgeo.org/grass72/manuals/addons/r.traveltime....

- ESRI has had those in web form since the 90s: https://doc.arcgis.com/en/arcgis-online/analyze/create-drive...

- GeoTrellis has that working in an open source project on top of a Spark cluster: https://transit.geotrellis.io/travelshed.html


Well, yes I can create isochrones myself indeed.

What I meant is the ability to generate them via an API without having to handle any GIS / routing data yourself and this for any city.

Handling these kind of services takes a lot of time, especially if this is only a sub-part of a more generic product.

Thanks for the alternatives though


The second option can be hosted at ArcGIS Online without you doing anything (i.e. loading anything). It is a REST API. Yes, it is hidden in their stupid docs.

The third option is faster than anything else, but would require you to load planet-osm.


Ha, didn't know that. I'll look deeper into the docs then. Thanks!


100% agree. I used their isochrone API several times for consulting work.

Thanks for mentioning this. Also keep in mind that mapzen its isochrone API:

https://github.com/valhalla/valhalla

as well as ours is open source:

ha, nice alternatives! I didn't know about graphhopper thanks! I'll be looking into them.


Mapnificent [0] seems to do something similar and I had some fun playing around with it for my city. It doesn't seem to go into as much detail as Mapzen and doesn't have an API, but it's open source.

Oalley [0] is a simple tool to draw isochrones and the REST API is available here: https://api.oalley.fr/

Bing has one: https://msdn.microsoft.com/en-us/library/mt814921.aspx


openrouteservice.org has them also, rest API also available
