Re: [mkgmap-dev] Address index for multi-country map
I know that sometimes a correct solution may be very difficult, and wtf, let's take a shortcut with a pragmatic solution. How complicated is a correct solution here? A correct solution requires to have complete and error free boundary relations for the whole world... ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] Address index for multi-country map
Thanks for your hints. With the precompiled boundaries, the map of the European countries receives a functional address index. When creating a map of South-East Asia (Thailand, Malysia, Singapore, Cambodia, Vietnam, Indonesia, Laos), the address index does not work: no roads are found in Bangkok or Kuala Lumpur! Beyond the fact of the defectiveness with South East Asia, that procedure does not feel correct at all: it means that I have to get the same (?) data from two different locations in two different formats. Or even three, when using the --precompiled-sea option (which I never got working with South East Asia). All those files have different update schedules which means inconsistencies. With central Europe, those inconsistencies are not very likely, since borders and coast lines are available with high quality. That does not apply to South East Asia. Last week I updated some sections of the Thai-Malaysian border, and today of the South-Thai coast. I know that sometimes a correct solution may be very difficult, and wtf, let's take a shortcut with a pragmatic solution.

Hi Bernhard, Bernhard Hiller wrote I know that sometimes a correct solution may be very difficult, and wtf, let's take a shortcut with a pragmatic solution. How complicated is a correct solution here? you can search the archives to find out why these solutions are preferred. The main reason besides performance is that a part of the world doesn't contain complete sea and probably also not complete boundaries. If you like, you can compile your own boundaries data: http://wiki.openstreetmap.org/wiki/Mkgmap/help/options#Create_Preprocessed_Bounds see also http://wiki.openstreetmap.org/wiki/Mkgmap/help/options#generating_precompiled_sea_yourself Gerd -- View this message in context: http://gis.19327.n5.nabble.com/Address-index-for-multi-country-map-tp5784034p5785017.html Sent from the Mkgmap Development mailing list archive at Nabble.com. ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] Address index for multi-country map
Meanwhile I did some experiments. With a fresh download from Geofabrik, I started with germany.osm.pbf without any additional modification by osmconvert. I split it, and created the map with the same parameters and style file. With the examples from Germany, I received the same results. Next, I removed the include sections from the style files and replaced them by the contents of the respective files. Same result. Next, I tried the default style (as of mkgmap 2724). Again, the same results. This means: it is not caused by a defect in my style file, nor in a defect in processing with osmconvert. Also a defect in resolving the include files can be excluded. Still, the data downloaded from Geofabrik could be defective. When I use the --country-name=Deutschland --country-abbr=DEU parameters, places are correctly found in Germany. The country Country is no more available. For small villages, the index is then OK. But for towns consisting of some quarters, it is still defective: there are no roads neither in Erlangen nor in Bayreuth, and the Geseeser Weg can only be found in Altstadt instead of Bayreuth. Next, I returned to mkgmap version 2654. I had to remove all lines with admin_level from relations, capital from points, the comparison of two values from lines. Also this did not solve the problem. That means, that the creation of the address index is broken somewhere in mkgmap. ___ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://lists.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
Re: [mkgmap-dev] Address index for multi-country map
Hello Bernhard, some time ago I had the same trouble. Once I understood it, I have set up the wiki page: http://wiki.openstreetmap.org/wiki/Mkgmap/help/Tags Have a look at the notes [3] and [4] You will need precompiled bounds.

[mkgmap-dev] Address index for multi-country map
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 10 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?
