Nominatim Help

[wolfbgn]

Hi, Vitalidze. I run Debian 8.7, Nginx 1.6, Traccar 2.12 with traccar-web. Every thing works perfectly with the provided url address of Nominatim server in the configuration file. I get the addresses right and displayed in Bulgarian. Recently I installed Nominatim 2.5. It is on the same machine. When I point my browser to 192.168.1.100/nominatim/ I am able to connect and view the page. In the upper right corner is "reverse search". When I press it I get http://192.168.1.100/nominatim/reverse.php?format=html. Original http://nominatim.openstreetmap.org/reverse Well I tried different addresses but I can not get it working with my Nominatim server. http://192.168.1.100/nominatim/reverse.php? http://localhost/nominatim/reverse.php? http://192.168.1.100/nominatim/ http://localhost/nominatim and many more. I am lost. Please help.

This URL should work: http://localhost/nominatim/reverse.php

Have you loaded mapping data to your nominatim instance?

To check the correct work you may perform some test query like this:

http://localhost/nominatim/reverse.php?format=json&lat=55.751244&lon=37.618423&zoom=18&addressdetails=1

This is the exact format traccar uses for querying nominatim services. You can put your own lat/lon pair instead of mine.

<entry key='geocoder.enable'>true</entry>
<entry key='geocoder.type'>nominatim</entry>
<entry key='geocoder.url'>http://localhost/nominatim/reverse.php</entry>

It is not working.

http://192.168.1.100/nominatim/reverse.php?format=json&lat=43&lon=28&zoom=18&addressdetails=1 Output: EOF {"place_id":"100175","licence":"Data © OpenStreetMap contributors, ODbL 1.0. http:\/\/www.openstreetmap.org\/copyright","osm_type":"node","osm_id":"31058194","lat":"43.2166104","lon":"27.9017131","display_name":"Варна, Varna Region, 9000, България","address":{"city":"Варна","county":"Varna Region","postcode":"9000","country":"България","country_code":"bg"}} I have Bulgaria only.

Looks like your set up is performed correctly. This address will appear for new positions only, have you checked new positions? Have you restarted service after making these changes? Also it makes sense to check tracker-server.log for error messages.

With these settings I get: 2017-02-21 08:47:51 DEBUG: [74ABE881: 5055 -> 192.168.1.6] - HEX: 485454502f312e3120323030204f4b0d0a0d0a 2017-02-21 08:47:51 INFO: Closing connection by disconnect 2017-02-21 08:47:51 WARN: Content is not allowed in prolog. - org.xml.sax.SAXParseException (DOMParser.java:257) 2017-02-21 08:47:51 INFO: device: 1, time: Tue Feb 21 08:47:55 EET 2017, lat: 43.223483, lon: 27.944801

If I put http://localhost/nominatim/reverse I get 2017-02-21 09:06:33 DEBUG: [F9634D45: 5055 -> 192.168.1.6] - HEX: 485454502f312e3120323030204f4b0d0a0d0a 2017-02-21 09:06:33 INFO: Closing connection by disconnect 2017-02-21 09:06:33 WARN: http://localhost/nominatim/reverse?format=xml&lat=43.223517&lon=27.944761&zoom=18&addressdetails=0 - java.io.FileNotFoundException (HttpURLConnection.java:1872) 2017-02-21 09:06:33 INFO: device: 1, time: Tue Feb 21 09:06:37 EET 2017, lat: 43.223517, lon: 27.944761

[vitalidze]

Hold on, you are using 2.12, which expects response to be in XML format. So the request must be something like this: http://localhost/nominatim/reverse.php?format=xml&lat=43.223517&lon=27.944761&zoom=18&addressdetails=0 (please note that URL must end with .php, like .../reverse.php). However, your version of nominatim seems to not support the XML format. Probably you need to install older version, or upgrade your traccar to the 3.0 version, which is working with JSON.

[wolfbgn]

I will install latest version of Traccar and update you. Thank you very much.

[vitalidze]

Well, you need to check your configuration parameters. It should be working with the request from my first reply.

[wolfbgn]

With google it works. With my server - no. Settings in default.xml

    <entry key='geocoder.enable'>true</entry>
    <entry key='geocoder.type'>nominatim</entry>
    <entry key='geocoder.url'>http://localhost/nominatim/reverse.php</entry>

I do not know what other settings to check for reverse geocoding.

[vitalidze]

I am out of ideas. Have you tried plain traccar installation without Traccar Web UI Mod? If yes, then please try asking same question on "backend" issue tracker https://github.com/tananaev/traccar/issues

[wolfbgn]

Thank you

Traccar 3.10 log: 2017-02-21 11:13:37 WARN: Geocoding failed - Unexpected char 69 at (line no=1, column no=1, offset=0) - JsonParsingExc$

[vitalidze]

Probably the reason is that your server prints EOF line in response as said in https://github.com/tananaev/traccar/issues/2940. You should try figuring out why the response looks like this, ask nominatim support, or maybe upgrade/downgrade your nominatim server.
