I have computed some isochrones using OSM route plugin but when I am trying to use the plugin again it gives me an error: An error has occured while executing Python code.

Is it working for you?

  • A more detailed description and the python traceback would be helpful. Mar 31, 2016 at 11:45
  • Traceback (most recent call last): File "C:/Users/Somebody/.qgis2/python/plugins\OSMroute\OSMroute.py", line 244, in run numberOfHits_start = child.attrib["numberOfGeocodedAddresses"] KeyError: 'numberOfGeocodedAddresses' Mar 31, 2016 at 12:13
  • Running in 2.14.0 on Mac OSX I get Traceback (most recent call last): File "/Users/my_name/.qgis2/python/plugins/OSMroute/OSMroute.py", line 245, in run if numberOfHits_start != "0": UnboundLocalError: local variable 'numberOfHits_start' referenced before assignment which suggests a similar cause as numberOfHits_start is the trigger for the error in both. I've tried copying the start and target addresses from the website's own geocoding but with no luck. Mar 31, 2016 at 16:09
  • As far as I know, it only works in Europe, are you trying to use it somewhere else?

  • I have tried for an address in Denmark from where I have already been able to compute isochrones before. I guess that it was just a temporary issue in the software because now it is back on track. Apr 1, 2016 at 10:51

OSMroute plugin does not work since OpenRouteService API has been changed. Furthermore, the author of OSMroute plugin explained in his blog post that he decided to stop further development of the plugin. In the blog post, you can find information about another alternative for computing isochrones in QGIS.


Looking at the plugin I played with the call to the geocoding server and discovered that it really is very sensitive to the address format. I got sensible results in Sweden only when using city names. Streets just didnt work

  • If you look at the Python code it sends a request to a server for geocoding but it is evidently not capable of parsing "weird" European addresses. It's not a character issue; "Gävle, Sweden" is fine but more specific addresses fail. I'll look into bypassing the geocoding bit but I'm still learning pgrouting and postgis myself, so don't hold your breath. Mar 31, 2016 at 18:33

    The server has been having problems of late which has caused both the plugin and the openrouteservice.org website to not respond or to behave oddly. But generally the geocoding is a little sensitive. The plugin is also in need of some work. I have looked at it and started on an improvement; as it is now it takes an address and converts that to WGS84 coordinates. I am working on an update that should allow you to enter WGS84 directly from the canvas. But don't wait on that to happen soon. Apr 4, 2016 at 11:16
