Hello all, As I understand it mkgmap uses the is_in tag (if present) to determine the region of a given city. If no is_in tag exists, it uses whatever was defined by --region-abbr in the command line, and if nothing was defined, then it uses nothing. If this is so, then why is --region-abbr is used instead of --region-name? After all, the is_in tags usually give a name, not an abbreviation. The workaround is just to set --region-abbr to the same as --region-name, but before I do this I wanted to check this wouldn't break something else. Thanks, Charlie
