I try to build a map of Germany, Switzerland, Austria and Czech Republic with a functional address index. I downloaded the Geofabrik extracts for those countries, combined them (after conversion to o5m format) with osmconvert, split them, and create the map. The result is quite mixed: some places show up below "Country" instead of Germany, e.g. - Addresses - Spell Country: Country - Spell City: Krummennaab - Enter Street Name: (stopped here, works) whilst - Addresses - Spell Country: Deutschland - Spell City: Krummennaab - No Results found Some places show up below "Deutschland", but (almost) no road is available: - Addresses - Spell Country: Deutschland - Spell City: Erlangen - Enter Street Name: (blank) - only "Buckenhofer Weg" available of a town with more than 100000 inhabitants... whilst - Addresses - Spell Country: Country - Spell City: Erlangen - Enter Street Name: (blank) - lists many roads of the town Near my home in Bayreuth is "Geseeser Weg". I choose that example because that street name does not exist so often. - Addresses - Spell Country: Country - Spell City: (Search All) - Enter Street Name: Geseeser - No Results found but - Addresses - Spell Country: Deutschland - Spell City: (Search All) - Enter Strret Name: Geseeser - lists "Geseeser Straße" and "Geseeser Weg" - select the latter - Enter House Number: 1 - lists "Geseeser Weg Altstadt Deutschland" and "Geseeser Weg Schnörleinsmühle". Since the part of Bayreuth is "Altstadt" (but no one would write that down as part of the address - it is Geseeser Weg 1, 95447 Bayreuth) select that - shows correctly on the map Let's try an example in Czeck Republic: Dukelská Ulica in Sokolov - Addresses - Spell Country: Ceská Republica - Spell City: Sokolov - No Results found but - Addresses - Spell Country: Country - Spell City: Sokolov - Enter Street name: Dukelská - Enter House Number: 1 - shows correctly on the map I know that I can use command line parameters for mkgmap: --country-name=Deutschland ^ --country-abbr=DEU ^ but that's not approriate here: there are 4 different countries to deal with. Otherwise, the parameters do their job correctly. According to the documentation, the style file should help mkgmap determine the country, and both my lines and points files say on their top: include 'inc/address'; How to solve this problem? Thanks for your hints.
