Description

Searched for postcode "N1", "N7" and "N17".

Postcode N17 centroid not in correct area. N17 belongs to Tottenham. (http://nominatim.openstreetmap.org/search.php?q=N17), Cannot find anything (node, way, relation) that caused the error (http://nominatim.openstreetmap.org/details.php?place_id=98395350)

Postcode N7 centroid returned no London result. N7 is missing (supposed to be in Nags Head, Holloway Road). (http://nominatim.openstreetmap.org/search.php?q=N7)

Postcode N1 centroid returned no London result. N1 is missing (supposed to be south of Mildmay Park). (http://nominatim.openstreetmap.org/search.php?q=N1)

Priority minor for error not breaking the software, but significant for returning possibly incorrect postcode centroids.

  • Summary changed from Postcode incorrect to Handle partial postcodes
  • Type changed from defect to enhancement

British postcode areas are not really mapped in OSM. So to properly recognize those postcodes needs some special handling of partial postcodes. This needs to be customized for each country.
