[mkgmap-dev] How can we use prefix/suffix feature in road names?From Ticker Berkin rwb-mkgmap at jagit.co.uk on Wed Apr 12 17:22:58 BST 2017
Hi Gerd Yes, was thinking of a substitution filter (like highway-symbol), but wondering where to put all the prefix/suffix rules, so that the style would be general. Although it is more of a language issue than country, mkgmap, with bounds.zip, has an admin tag for the country. But, for simple implementation, could just get fixed set of prefix/suffix from a command line arg or file.
