routing-api's Introduction

Itinero API

This project is an implementation of a basic routing API based on Itinero. It loads RouterDb files from a configured folder and exposes one routing instance per file.

Goal

This project serves both as a demo project for Itinero and an easy way of setting up a routing instance.

Setup

Basically you need build the project and place a RouterDb file into the configured data folder.

Install .NET core for your platform.
Run the build script, build.sh or build.bat on windows.
Then download a RouterDb file or create one using the Itinero data processing tool.
Place the RouterDb file into the configured data folder, by default this is ./src/Itinero.API/data. Configuration file is here.
Run the run script, run.sh or run.bat on windows.

You should new see the service reporting messages on loading the RouterDb's you configured:

[Bootstrapper] information - Loading all routerdb's from path: \path\to\src\Itinero.API\data
[Bootstrapper] information - Loaded instance luxembourg from: \path\to\src\Itinero.API\data\luxembourg.c.cf.routerdb
Hosting environment: Production
Content root path: \path\to\src\Itinero.API
Now listening on: http://localhost:5000
Application started. Press Ctrl+C to shut down.
[Bootstrapper] information - Loaded instance belgium from: \path\to\src\Itinero.API\data\belgium.c.cf.routerdb
[Bootstrapper] information - Loaded instance netherlands from: \path\to\rc\Itinero.API\data\netherlands.c.cf.routerd

API

When the service is setup one instance per RouterDb will be available. The name of the instance is identical to the name of the file until the first '.'. For example, 'belgium.c.cf.routerdb' will be 'belgium'.

By default when opening your browser at http://localhost:5000/ there will be a list with loaded instances. When you click one of the instances a map will open centered on the loaded area, clicking on the map still set a startpoint and clicking again an instance.

The following is available:

http://localhost:5000/ : A list of loaded instances.
http://localhost:5000/{instance} : The map centered on the loaded area in the instance with routing enable for cars.

The API:

http://localhost:5000/{instance}/routing : Accepts requests using the following parameters:

profile: One of the profiles loaded in the RouterDb, think car, bicycle or pedestrian.
loc: Add this parameter at least twice, first is startpoint, last is the destination.

Make sure to ask the API for JSON by adding Content-Type: application/json header. The route is returned as GeoJson.

Example: http://localhost:5000/belgium/routing?profile=car&loc=51.055207,3.722992&loc=50.906497,4.194031

routing-api's Issues

Add a dockerfile for easy deployment using Docker

This is based on the request in this issue:

itinero/routing#182

It's a great idea and has been done before but was never open-sourced.

Router.Resolve crashes - not sure what to do

My routing program has been running well, many thanks for a superb package.

However today I came across a crash. I am using .net Maui

Here is my code

  public double ItineroDistance(PostcodePosition pp1, PostcodePosition pp2)
  {
    // calculate a route.

    // snaps the given location to the nearest routable edge.
    var start = router.Resolve(profile, (float) pp1.Latitude, (float) pp1.Longitude);
    var end = router.Resolve(profile, (float) pp2.Latitude, (float) pp2.Longitude);

    var route = router.Calculate(profile, start, end);

    return route.TotalDistance; //(in meters)
  }

pp1.Latitude was 53.033809 pp1.Longitude was -2.151793
pp2.Latitude was 52.807553 pp2.Longitude was -1.740858
The profile is "car"
I obtain these from UK Postcodes ST1 6SS and DE13 9RD
https://api.postcodes.io/postcodes/

The exception
Itinero.Exceptions.ResolveFailedException: 'Could not resolve point at [52.807552, -1.740858]. Probably too far from closest road or outside of the loaded network.'

On OpenStreetMap (which I'm using)

On Google

What would be the best way to handle this? Use a try catch? Then what would I do in the catch? I could just do a CrowFlies calc (I have some code for that) I suppose. Or is it a bug?

Thanks for any suggestions, advice, help.
Gordon :)

AddContracted

I have been using the API to get distances between two points in the UK for a while, the code works very well with no issues, I have been working on shortest distances, but now the requirement is to calculate both the shortest distance and fastest route at the same time so two router calculated at the same time, the processing time has gone from 1-3 seconds to 30+ seconds. I want to know if I am on the right track with doing the following:-

var routerDb2 = new RouterDb();
using (var stream = new FileInfo(@"d:\osrm\gb.osm.pbf").OpenRead()) {
routerDb2.LoadOsmData(stream, Vehicle.Car);
}

routerDb2.AddContracted(Vehicle.Car.Shortest());
routerDb2.AddContracted(Vehicle.Car.Fastest());
Router router2 = new Router(routerDb2);

using (var stream = new FileInfo(@"d:\osrm\contracted-gb.routerdb").Open(FileMode.Create, FileAccess.ReadWrite)) {
routerDb2.Serialize(stream);
stream.Flush();
stream.Close();
}

So adding two contractions into the same file, I did try building two files each with one contraction each but this was slow.

Then in Calculate doing the folllowing:-

    public Result<Route> Calculate(string type, Coordinate[] coordinates)
    {
        var fastest = Itinero.Osm.Vehicles.Vehicle.Car.Fastest();
        var shortest = Itinero.Osm.Vehicles.Vehicle.Car.Shortest();
        var points = new RouterPoint[coordinates.Length];
        if (type == "Fastest") {
            for (var i = 0; i < coordinates.Length; i++)
            {
                var result = _router.Router.TryResolve(fastest, coordinates[i], 200);
                if (result.IsError)
                {
                    result = _router.Router.TryResolve(fastest, coordinates[i], 2000);
                }
                if (result.IsError)
                {
                    result = _router.Router.TryResolve(fastest, coordinates[i], 20000);
                }
                points[i] = result.Value;
            }
            return _router.Router.TryCalculate(fastest, points);
        }
        else {
            for (var i = 0; i < coordinates.Length; i++)
            {
                var result = _router.Router.TryResolve(shortest, coordinates[i], 200);
                if (result.IsError)
                {
                    result = _router.Router.TryResolve(shortest, coordinates[i], 2000);
                }
                if (result.IsError)
                {
                    result = _router.Router.TryResolve(shortest, coordinates[i], 20000);
                }
                points[i] = result.Value;
            }
            return _router.Router.TryCalculate(shortest, points);
        }
    }

Or is it better to run two routers if so how do I change the port from 5000 to something else I could run one on 5000 (fastest) and one on 4000 (shortest), I have loads of RAM in the server so running two instances is not a problem.

Thank you for all your efforts, great piece of code!

Host API behind Apache

Hello,

I followed those steps to run the API behind Apache : https://docs.microsoft.com/en-us/aspnet/core/publishing/apache-proxy

No problem at all to configure Apache (even though I didn't follow the guide at all) !
But I can't manage to create a service that starts :P

Here is my routing-api.service file ; what did I miss ?

[RouterBaseExtensions] information - Profile(s) bicycle not cached, building cache.

Hi~!
I'm using your project to build an application for riding planning. However,I got a problem,

When I send the following request to the routing-api server, an error occurs.

http://localhost:5000/taiwan/routing?callback=itinero.JSONP.callbacks.route4&profile=bicycle&loc=24.196477,120.693312&loc=24.197671,120.690608&sort=true

[RouterBaseExtensions] information - Profile(s) bicycle not cached, building cache.

RouterDb generated using official tools
Build a RouterDb for pedestrians and bicycle and add a contracted graph for both:
idp --read-pbf path/to/some-file.osm.pbf --pr --create-routerdb vehicles=bicycle,pedestrian --contract bicycle --contract pedestrian --write-routerdb some-file.routerdb

Install on Debian 9

Hi,

I tried to install routing-api on a Debian 9 server.
No problem to install .NET core following https://www.microsoft.com/net/core#linuxdebian

But when I execute ./build.sh, here is the error I have (see hereunder).
Unfortunately, I not used enough to .NET to know how can I fix it. Could you help me ?

Thanks

Hello, I would like to know how to determine the location?

Identify the Notes

On a route how can I identify the Notes, like this?
To route I used this:

var result = instance.Calculate(profileName, coordinates);

Any ideas?

How to switch profile ?

The API works fine with belgium.c.cf.routerdb and car profile but how can I change profile ?

I loaded belgium.a.routerdb file but when I try profile=pedestrian I have "Profile with name 'pedestrian' not found." error.

How can I define which profile I want ?
How can I use the belgium.a.routerdb file (where a is for all I guess) ?
Is it possible to have a list of loaded profiles ?

Thanks.

Default response should be json

The building cache part runs for hours with no result.

Check for new files

Check for new files in the configured routing db folder. When a new routerdb is placed there it should be picked up automatically.

demo url cause error

I am trying http://localhost:3467/belgium/routing?profile=car&loc=51.055207,3.722992&loc=50.906497,4.194031
but get error:
Nancy.RequestExecutionException: Oh noes! ---< System.ArgumentException: View name and model parameters cannot both be null.

How to fix this?

Cannnot use with RouterDB created from latest Itinero project

I created this routerdb using the https://github.com/itinero/routing repo.

I can provide a code example of how I created it if required.

tutorial or guide

Could you create a tutorial for beginners. That it would be easy to understand what to do. You have indicated the steps, but there are many question

Error 500 (Nancy)

If I use the example http://localhost:5000/belgium, everything seems to work as expected : I can click 2 points in the map and the route is calculated between those 2 points.

But if I request the API (in my browser) by going to http://localhost:5000/belgium/routing?profile=car&loc=51.218927,2.905884&loc=49.676515,5.814514 I have an error 500 from Nancy.

When I make the same request with cURL it does work though ...

Any idea ?
Thanks !
