Hello, I got a tool that detects longitude and latitude of specific cities with postal code + city name in the query. I took the first place that is returned automatically, because there are many requests I had to do one time for our database. Unfortunately, when I search for München in Germany, the first result is not the correct city, even when I request it with the right postal code and the first result got another postal code: http://nominatim.openstreetmap.org/search?q=81660+M%C3%BCnchen+DE&format=xml&addressdetails=1 Can anybody provide me any solution? asked 19 Sep '13, 14:19  modiX |
One Answer:
If you know that you are looking for a postcode + city, it is better to use structured requests (see search parameters in the Nominatim docs for details). So your example should be: Although this specific postcode seems to be missing in OSM, so the query does not give any results at all. A word of warning at this point: support for postcodes in Nominatim is very rudimentary still, so results should always be taken with a grain of salt. answered 19 Sep '13, 15:07  lonvia |
I wished this would solve my problem :/
hey modiX,
Please check your postalcode: 81660 is NOT a geographical postalcode in Germany. It is more a Postalcode for big institutions like companies, banks or authorities inside Germany, a so called "Großkunden-Postleitzahl" in German.
Thus you can address an institution without mentioneing a street name.
These special postalcodes should NOT be stored in OSM. So you will not find it there. Please retry with a postalcode that covers a kind of area like a suburb of Munich or similar.
You are right, thanks. the real postal code 81671 results the correct München in Bayern at both cases (full query and OSM). So my only work-around would be to replace the industry postal code with the geographic postal code. Unfortunately I cannot find any list in the web, but this is another problem case. Thanks so much! :)
