Hi Ben, thanks for the details. I did not think about an error in the OSM data because we already have a few special rules for other big towns, e.g. in Germany wie have Hamburg, Bremen and Berlin which are special because politically they also have the role "Bundesland" like Bavaria or Lower Saxony. Also, I tried older boundary files and Ottawa never appeared as admin level 8.
Maybe I can code a test routine for the boundary data that uses the geonames data from http://download.geonames.org/export/dump/ to verify that a POI created for that location has the mkgmap:city tag filled with the proper name.

The current Ottawa boundary describes a municipal level entity composed of the a bunch of former small cities (including the city of Ottawa which is now downtown area of Ottawa). Looking at Canada in the administrative boundary list and using Toronto as an example, the current Ottawa boundary should be admin level 8. https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative The National Capital Region should be admin level 6 but I can't find a boundary for it. https://en.wikipedia.org/wiki/National_Capital_Region_%28Canada%29 The suburbs within Ottawa (the former full cities) should be admin level 10. Again there are no boundaries but these suburbs are used officially for addresses. For instance, you can find Kanata listed in the Canada Post postal code lookup app. https://www.canadapost.ca/cpo/mc/personal/postalcode/fpc.jsf It looks like the address setup in mkgmap is incorrect for this setup because admin level 10 is what people use for addresses in the big cities in Canada. I can fix this and send a patch. As for your original question, I think adding the safety catch at the end would be a good idea just in case there are other areas that have broken data. or should we add a one to this block: mkgmap:city!=* & mkgmap:admin_level8=* { set mkgmap:city='${mkgmap:admin_level8}' } mkgmap:city!=* & mkgmap:admin_level7=* { set mkgmap:city='${mkgmap:admin_level7}' } mkgmap:city!=* & mkgmap:admin_level9=* { set mkgmap:city='${mkgmap:admin_level9}' } mkgmap:city!=* & mkgmap:admin_level10=* { set mkgmap:city='${mkgmap:admin_level10}' } e.g. a further line with mkgmap:city!=* & mkgmap:admin_level6=* { set mkgmap:city='${mkgmap:admin_level6}' } Nice catch!

Adding an additional line like the 2nd below solves the problem: # Canada mkgmap:country=CAN & mkgmap:region!=* & mkgmap:admin_level4=* { set mkgmap:region='${mkgmap:admin_level4}' } mkgmap:country=CAN & mkgmap:city!=* & mkgmap:admin_level6=Ottawa { set mkgmap:city='${mkgmap:admin_level6}' } mkgmap:country=CAN & mkgmap:city!=* & mkgmap:admin_level8=* { set mkgmap:city='${mkgmap:admin_level8|subst:City of }' } or should we add a one to this block: mkgmap:city!=* & mkgmap:admin_level8=* { set mkgmap:city='${mkgmap:admin_level8}' } mkgmap:city!=* & mkgmap:admin_level7=* { set mkgmap:city='${mkgmap:admin_level7}' } mkgmap:city!=* & mkgmap:admin_level9=* { set mkgmap:city='${mkgmap:admin_level9}' } mkgmap:city!=* & mkgmap:admin_level10=* { set mkgmap:city='${mkgmap:admin_level10}' } e.g. a further line with mkgmap:city!=* & mkgmap:admin_level6=* { set mkgmap:city='${mkgmap:admin_level6}' } I assume that there are more large cities with this problem. Does anybody know how to find them without mkgmap ?
