Short Announcement: New OSM routing plugin for QGIS OSM Tools

Two years ago I wrote the OSMroute plugin which enable the QGIS user to use the OpenRouteService API for geocoding of points, accessibility analysis as well as routing from A to B. Unfortunately the managing of a plugin/ open source tool is time-consuming/ hard. But fortunately Nils Rode lifted the plugin to a new level: OSM tools.

OSM Tools Plugin

The plugin can be installed as a normal plugin via the plugin manager:

The usage is quite easy and enable you to geocode/reverse geocode addresses, find routes, create an isochrone map. Yet as the API from openrouteservice.org is an open one there are some limitations on the API:
  • 500 free requests per day in total
  • 40 requests per minute

You could be easily affected by these restrictions as the API allows some batch jobs. The batch mode enables you row-by-row or row-by-any routing.

different types of batch modes.

The result is really good: a clean feature table with all the needed information of the routes:

Nils did a great job on this one and I encourage everyone to use this with your own API key, look for issues with it (and report them!) and help this plugin to grow!

Are there any plans to enable this to work in the UK. I saw this and added it to my copy of QGIS as it would be a fantastic addition, but when I tried it, it wouldn’t work

Thank you for intrucing this very useful tool. When trying the tab accessibility areas, I always get an error with the conduction in the python script. Does anyone has an idea how to solve it?

Hi Gisacka,

as Riccardo wrote, please post issues here:
https://github.com/nilsnolde/ORStools/issues

Please include the URL used (w/o key). You can get it via the Python console in QGIS, it´ll print the URL when making a request.

I have a problem for accessibility areas distances when I use the use layers function. There is a python error each time.
File “C:PROGRA~1QGIS2~1.16appsPython27libjsondecoder.py”, line 383, in raw_decode raise ValueError(“No JSON object could be decoded”) ValueError: No JSON object could be decoded
The time function works very well. What does this come from?
