Introduction
YOURS goal is to use OpenStreetMap data to make a routing website utilizing as much other (opensource) applications as possible. Currently integrated applications are:
- Gosmore, the routing engine.
- Namefinder, the indexing service.
- Route altitude profiles SRTM
- OpenLayers, slippy map framework.
Name
As there are already a number of route services using OSM data it becomes more difficult to find a suitable application/project name. Each ones name contains relevant words like 'open', 'service', 'route', etc. So I thought of 'Yet Another Openstreetmap Routing Service' short YAORS which sounds like 'yours' hence: YOURS. As in 'your route service'...oh well :-)
Features
- Generate fastest or shortest routes in different modes:
- using all available roads for Car, Bicycle and Pedestrians .
- using only national, regional or local cycle routes/networks for Bicycle.
- Unlimited via points (waypoints) to make complex routes.
- Drag and drop waypoints moving.
- Drag and drop waypoint ordering.
- Geolocation: Lookup street- and placenames to determine their coordinates.
- Reverse geolocation: Lookup coordinates to determing their street- and placenames.
- Generate route altitude profiles.
- Download routes as GPX file so the route can be put onto a GPS device for trackback.
- Provides a routing calculation API that returns KML or geoJSON.
- Allow quick editing of the current mapview using a link to the online 'Potlatch' map editor.
- Single click map/route data testing.
- Show the date of the planet-latest file on which the routing database is based.
- Client-side (session based) route caching.
- Automatic zoom to location of the user based on geoIP.
Compare YOURS against other online OpenStreetMap navigation websites.
Development
YOURS code is available under the BSD license. You can download the code for version 1 (as shown on http://www.yournavigation.org) from the OpenStreetMap SVN server:
svn co http://svn.openstreetmap.org/applications/routing/yours/branches/version-1.0-via
The developer version which will support route via's and driving directions will be committed to the trunk of the repository in a few weeks.
Contributors please check out the branch 'version-1.0' only. SVN trunk is not yet up to date!
svn co http://svn.openstreetmap.org/applications/routing/yours/trunk (Do not use this link)
Contact, bug reports and feature requests
Bug reports and feature requests should preferably be done as Trac tickets assigned to the YOURS project. You can also add your comment to the discussion page or forum topic. For other stuff you can email me: osm at na1400 dot info but I'm also often present on the irc channels #osm and #osm-dev between 09:00 and 23:00 CET.
Contribution
Any help in making YOURS better is welcome! Please refer to a ticket when committing your changes like:
Added new feature blah (refs #1234)
Where 1234 is the ticket number requesting the new feature or bugreport
Known issues
There is a list of active Trac tickets. A list of sub-optimal or weird routes is listed here.
-
Very long routes can't be exported in GPX format. This needs a different implementation approach (YOURS). - The route altitude profiler only works for routes with less then 400 nodes (YOURS).
- Gosmore is not designed for generating very long routes (> 200km).
-
No routing in the Northeastern part of the American continent (Server/hosting). -
Due to server limitations the American continent is devided into three sections: Northeast-, Northwest- and South America. Route calculations can't be performed when the route goes from one section to another (Server/hosting/YOURS). -
Non-standard ASCII characters are currently not supported by the YOURS Namefinder interface. I assume this affects a lot of non-western countries, but so far I've only received feedback on this from Germany and Denmark...(YOURS). -
Oneway restrictions on roads tagged using oneway=true are disregarded (Gosmore). -
Some routes cannot be calculated (Gosmore). -
Internet Explorer fails to show the route altitude graph (YOURS). Fixed thanks to Tobias Lindh.
Altitude profile
The altitude profile is based upon SRTM data which comprises multiple terabytes of data when covering the world but sponsored servers usually don't have that amount of storage available. A possible solution for this is to spread the data over a number of servers. Below is a list of currently supported servers by YOURS. Please send me a message if you have configured a server yourself and want YOURS to support it too. If you decide to configure a profile server please make sure to overlap the neighboring areas by e.g. 1 degree as that will make generating profiles easier.
| Host | Base URL | Area description | Area bbox |
|---|---|---|---|
| Metacarta | http://labs.metacarta.com/altitude/profile/ | North and South America | N60 W-179 S-56 E-44 |
| Komяpa | http://altitude.komzpa.net/profile/ | Belarus | N57 W23 S50 E33 |
The website
Setup instructions
Prerequisites
- I assume that a webserver with PHP is already available. If not, there are many manuals on the internet on how to get this running.
- SVN tools are needed to get a copy from the repository. Contact me for a zip file if you don't have (or want) SVN tools installed.
Installing Gosmore routing engine
- Get a copy of Gosmore following the instructions from: Gosmore
- Download a precompiled map as described in the link above, name it gosmore.pak and put it in the same directory where Gosmore resides.
- Alternatively you can download a planet dump or planet extract from: Planet and convert it into a gosmore.pak following the instruction on the Gosmore wiki page.
Installing YOURS website
- Go to the public html directory and get a copy of YOURS using the SVN command:
svn co http://svn.openstreetmap.org/applications/routing/yours/trunk/www yours
You should now have a directory named 'yours' in the public html directory.
- Open gosmore.php in the API directory, e.g.: yours/api/dev/gosmore.php and put the correct path the the yours www directory ($www_dir), the path to the gosmore routing engine ($yours_dir) and an email address for the administrator (only used to notify API abusers) so you may leave it blank.
Finally
Start your browser and go to: http://server_ip_address/yours and enjoy!
Embedding YOURS into 3rd party web application
[TODO]
Websites that run their own instance of YOURS
- OpenStreetMap.cl OpenStreetMap chapter of Chile.
- BigTinCan makes mobile navigation software.
API documentation
If you would like to embed some of the functions of the YOURS website in your own site or application then you can incorporate the API. The API is described below.
Usage
Use of the API is on a Fair Use Policy basis: everyone can use the API as long as it won't overload the server systematically. If you do overload but provide an X-Yours-client header (as described below) then I'll try to contact you to find a solution. If you don't provide this information (or I can't contact you) then you might become blocked (this has happened only once so far, so don't worry too much about it).
Speed/Reliability
The sponsored server that runs www.yournavigation.org only has 2 GB ram but the routing database is about 12 GB. This forces the server to move blocks of data in and out of ram when there are multiple concurrent users that request routes all over the world. Despite the speed with which Gosmore is able to calculate routes in optimal conditions, the harddisk seeks will slow the server down almost completely in case of such situation and new requests might be rejected if there are already too many concurrent requests running (this happens quite often unfortunately, multiple times per day). There is not much that can be done about it unless the server is upgraded with more ram and/or an SSD harddisk (Hint!).
API revisions
The API can have multiple revisions. In each version the interface is kept unchanged to prevent 3rd party applications from becoming broken. Each API version is kept in it's own directory which allows multiple API versions to operate simultaneously without interfering with each other. 3rd party developers can then gradually move from one version to another without being forced to do so on short notice. Note: The API interface can change without notice as long as it's called 'dev'.
The current API revision is '1.0'. The 2.0 API is being developed as 'dev'. The base URL for each API is:
http://www.yournavigation.org/api/, so the 1.0 API is located at: http://www.yournavigation.org/api/1.0/ and the dev API is located at: http://www.yournavigation.org/api/dev/.
Version 1.0
Clients of this API version are kindly requested to identify themselves using an extra HTTP header: X-Yours-client. This way the (amount of) users can be tracked and appropriate action taken if a 3rd party application is overloading the service or otherwise misbehaving. E.g. the yournavigation website is identified by X-Yours-client: www.yournavigation.org.
Routing API
The routing API provides routing information based upon a given start/end location and some route parameters like the vehicle type, etc. The resulting route is returned as a KML file containing all the nodes from start to finish. If Gosmore is unable to successfully calculate a route then the most complete route so far will be returned.
Base URL
http://www.yournavigation.org/api/1.0/gosmore.php
Parameters
Available parameters are described below. Only the location parameters are required. All other parameters are optional, they will use the default value when omitted.
- flat = latitude of the starting location.
- flon = longitude of the starting location.
- tlat = latitude of the end location.
- tlon = longitude of the end location.
- v = the type of transport, possible options are: motorcar, bicycle or foot. Default is: motorcar.
- fast = 1 selects the fastest route, 0 the shortest route. Default is: 1.
- layer = determines which Gosmore instance is used to calculate the route. Provide mapnik for normal routing using car, bicycle or foot. Provide cn for using bicycle routing using cycle route networks only. Default is: mapnik.
- format = specifies the format (KML or geoJSON) in which the route result is being sent back to the client. This can either be kml or geojson. Default is: kml.
Example URL
Export API
YOURS can export a route in different formats, like Waypoints or GPX track. Provide the route and it will return the route in the requested format.
Base URL
http://www.yournavigation.org/api/1.0/saveas.php
Parameters
- type = the type of output format, possible options are: gpx (GPX track), wpt (Waypoints).
- data = the source route in lat/lon pairs. Each pair is separated by a comma character while the lat/lon values are separated by a space character.
