The Geocoding API gets an improvement regarding
Keep us informed if something got worse for your results! And of course also let us know if it is better :)
When certain areas are disconnected from the main network we remove them completely to avoid start and end requests there, which would result in 'connection not found' issues if the other point is in the main network.
Probably this area is too small.
Currently the daily credit limit is a 'rolling limit' and resets when you use it. E.g. if started on 6pm with querying then the limit is reset on the next day if a request comes in at 6pm or later.
You can always see the reset date and remaining credits when reading the header of one request, see here for more information.
and further options like force to avoid overlap (use the Isochrone API to calculate distinct delivery areas), merge polygons, one polygon per location etc
Will be fixed in a few minutes ...
Thanks for this :) !
Two minor documentation mistakes:
i.e. minimize the overall makespan then change the algorithm object to:
Algorithm Example -> Objectives Example?
Does the GraphHopper Directions API has the ability to "re-route" the user if they deviate from the directions? i.e. will it automatically update the set of directions or is there some function to determine if the user is still on/off track?
There is no such functionality offered directly via the Routing API, but you should be able to do this easily on the client side via calculating the distance to the route and fetch a new route depending on your requirements. E.g. for Java you could use this snippet to calculate the distance, and then do this for the first 100 points or only for points of the turn instructions.
See these coordinates:
https://graphhopper.com/api/1/matrix?point=53.600859,8.304977&point=53.639753,8.246269&type=json&vehicle=car&debug=true&key=[YOUR_KEY]&out_array=times&out_array=distances
Of course, you have to replace YOUR_KEY
The response in this example is:
{"message":"Bad Request",
"hints":[{"details":"java.lang.IllegalArgumentException","message":"Cannot find from_points: 1"},
{"details":"java.lang.IllegalArgumentException","message":"Cannot find to_points: 1"}]}
Here is the GraphHopper Maps query with the same coordinates.
limit
for reverse geocoding is 5, for normal search is 15E.g. that default size is 0
This was deployed to the routing API on 8th June
The handshake for SSL is expensive as many times it needs to send forth and back something. So the solution is to keep this handshake at the initial request only (our server should support this via keepalive
) and follow up requests are much faster, which you can try e.g. via:
URL="https://graphhopper.com/api/1/route?key=[YOUR_KEY]&point=-34.0102021%2C151.1270069&point=-33.95237450124232%2C150.9959234857656&vehicle=car&locale=en"
curl -w "tcp: %{time_connect} ssl:%{time_appconnect} all: %{time_total}\n" -sk -o /dev/null $URL -o /dev/null $URL -o /dev/null $URL
Another solution will be established in the future to have several servers across the world. Initial connections can be tested from various locations with this service
Our Java and JavaScript clients already do this 'keepalive' for you as JavaScript uses the default for HTTP1.1 and Java uses okhttp having similar defaults.
ReDoc is really useful for displaying an explorable API with swagger spec. See e.g. here
We should set this up on our servers.
There is currently no 'full-blown' JavaScript, instead we suggest to have a look on our JavaScript code from GraphHopper Maps (Apache License 2.0)
https://graphhopper.com/maps/js/main.js
https://graphhopper.com/maps/js/ghrequest.js
Additionally we need to provide a separate example for the Geocoding and Matrix API.
Question:
I am really confused in using Route Optimization API. I just cloned the directions-api-vrp-java-client. Now i want to test the example given. So what should i do after cloning the API from the repository. Could you guys be able to provide a documentation for this as well. I am just a beginner in android programming.
Answer:
After you cloned the repository execute the steps described under 'Maven' to build the client jar locally and include the maven xml snippet in your project. Then use one of the examples to use the API for your needs.
Hi,
i was wondering how do i transform the default answer to a valid geojson?
beacuse neither leaflet or geojson.io understand a the answer using Routing API
example:
curl "https://graphhopper.com/api/1/route?point=-34.608053,-58.459734&point=-34.709718,-58.675684&vehicle=car&locale=es&debug=false&points_encoded=false&key=[mykey]" > line_answer
and my answer:

Maybe use multiple time_limit parameters to support this? (Then we can also avoid the buckets
parameter)
We got a request asking for how to do an API request via PHP. The most important part is to use the correct URL:
<?
$adr='https://graphhopper.com/api/1/geocode?q=' . urlencode('Deutschland Berlin') . '&locale=de&key=[YOUR_KEY]';
$str=file_get_contents($adr);
echo $str;
?>
Or for the routing API:
<?
$adr='https://graphhopper.com/api/1/route?point=' . lat1 . ',' . lon1 . '&point=' . lat2 . ',' . lon2 . '&locale=de&vehicle=car&key=[YOUR_KEY]';
$str=file_get_contents($adr);
echo $str;
?>
Then use the $str for further JSON parsing or use httpful a HTTP client making such requests easy for PHP.
Our route optimization API contains a swagger specification from which you can easily create an already working PHP client. Contact us if you do not know how to handle that.

What is an isochrone calculation? Is is also called reachability or walkability. Read at Wikipedia.
Please contact us to take part as an alpha tester. See a simple example and the Isochrone API documentation

Hi and thanks for this great piece of software.
I have installed graphhopper successfully on my EC2 instance and it works perfectly as for the routing api.
I wonder if the geocoding API is excluded from the local installation or has to be enabled somehow, becaue it seems to be not reachable under hostname:port/geocode or hostname:port/api/1/geocode , as documented in your docs...
Reduce the number of returned points, but the hardest part is to always avoid then self-intersecting polygons.
This returns time and distance == 0 but should either throw a RuntimeException (would be consistent with the Routing API) or an 'infinite' value to still use parts of the results.
Although we normally prefer fail fast, I would prefer an 'infinite' value here. Some other Matrix API providers return negative values which I don't like too.
I need to route on railways line using graphhopper instead of car. Could you please guide me how to do that using api? I need to provide following options http://wiki.openstreetmap.org/wiki/Key:railway.
We've implemented a first version for truck routing, ie. a vehicle considering weight, height and width access restrictions as long as these properties are available in the OpenStreetMap data (can be added fast). The specific truck properties are published here, the bus profile is not a 'public transportation' bus, instead it is a truck with the properties of a bus and can be used as an overland bus. A customized version is currently only possible via a customized package or self-hosted version.
We'll improve especially the ETAs in the coming months at the same time where we improve it for the other vehicles.
After email exchange with Peter K, it seems like using the response header of every response (not only the errors, see https://graphhopper.com/api/1/docs/#http-error-codes) to determine the remaining credits is currently not working as the headers are not properly set.

By looking at Firebug's logs, it seems that the Access-Control-Expose-Headers key is not set in the response header (whereas the Access-Control-Allow-Origin is indeed set to 'widlcard').
It would be nice to know, before sending a routing request to the API, what is the maximum locations per request allowed with our API key. This number varies with GraphHopper account types. E.g. 5 with Free accounts, 30 with Basic accounts, etc.
Currently, there is no way to programmatically know if my routing query with n locations will be allowed, other than issuing it and check if it returns an error or not.
My first use case is the GraphHopper Maps UI. Creating a new intermediate point could be disabled once the maximum allowed count of intermediate points is reached.
E.g. if using a free account (max. 5 locations: start, end and 3 intermediates), and you already defined 3 intermediate points, then the + icon in the left margin to add a new location would be disabled, as well as the "Add intermediate point" item in the context menu.
You should create and return a new key max_locations
in the answer to the info
endpoint calls.
distance is not 'debatable' but time_limit can be

We should not only support GPS coordinates but also open location code from Google. Standing under Apache License. See here for a good comparison where open location code stands out from its logical point of view and being pure algorithmic based as well as the code license.
We need to clarify
An alternative would be https://github.com/roberdam/Xaddress
This would reduce documentation a bit and makes exploration a bit simpler: just docs and tutorials.
Answer
yes, if you use the Routing API - please see GraphHopper Maps where we do so. The Route Optimization API does not provide it yet. But still you can fetch the route from the Routing API via the optimized order of locations like we do in the examples. Or if you only want a simple optimized route without constraints use the Routing API with optimize=true
extend the swagger spec to include map matching
Question:
If we search for a street name including house number, why is it not included in the search suggestions?
Answer:
Our address search is really dependent on good data and although in central Europe the data is really good it is not yet perfect, especially for house number precision. But regarding your specific example (hidden exampe) it seems that our software is to blame, not the data. We will investigate
Hello ,
what is the best way to use GraphHopper with FFWDME.JS ?
As Isochrone API already uses ch.disabled=true we could easily support turn restrictions. Enable and test this.
We are working on this.
Since End of April our Tour Optimization API is available for selected developers. Since Mid-May it is available for all developers. Keep in mind that it is not yet suitable for production usage. If you intend to use it please contact us before.
Refer to the following information
See discussion graphhopper/graphhopper#677
How to use the GraphHopper Directions API with Python?
This project shows some basics. We'll improve and create a python notebook from it or maybe even something which runs in jupyter
The currently untested python client for the GraphHopper route optimization API is located here
Customers which require this together will need to fetch the optimized order via JSON and convert it to GPX on the client side (for now).
It would be nice to know, before sending a routing request to the API, what vehicle types are allowed with our API key. Some GraphHopper account types don't have access to all vehicle types, e.g. free accounts have access only to car, foot and bike.
Currently, there is no way to programmatically know if, say, mtb
vehicle will be allowed, other than issuing a routing API call and check if it returns an error or not.
From the documentation:
features
A json object per supported vehicles with name and supported features like elevation
It is not clear if "supported" refers to the API system itself, or to my specific key used to call the info
endpoint.
Currently, all vehicle types supported by the API are returned, regardless of the given API key.
Expected:
Either only vehicle types supported by the key are returned.
Or a new key is created and returned, telling about allowed vehicles types for the given key.
In all cases, the documentation should be updated and made clear.
It seems that GraphHopper Maps does not receive gzipped result which makes it also feel a bit slow.
Hi,
Please see our issue here related to routing through gates - in short - car routing doesn't pass through gates that doesn't have an access restriction when it should
IsraelHikingMap/Site#185 (comment)
You can play around with the routing here - the following case is where a small settlement has an entrence gate that can be passed but still should be mapped:

From the external geocoding provider sections, the link https://nominatim.openstreetmap.org/ is not accessible.
It would be nice if a created API key would be renameable. Workaround would be to create a new one. So not really a pressing issue.
