Thanks to Thorsten for the valuable hint ...
This quick-and-dirty solution solves the problem:
An alternative solution could be this ("admin_level 7" will completely be ignored):
In germany "admin_level 7" is used for special or artificial administration regions. Mostly they are called "Ämter", "Verbandsgemeinden" or "Verwaltungsgemeinschaften". People typically don't use these objects as starting point for an address search. But this solution needs some more quality assurance ... I want to verify the "address index" against an official german register (called AGS "Amtlicher Gemeindeschlüssel").
Question: How is it possible to print out the content of the address index (mdr file) ?
Regards Klaus
Hi Klaus, do you want to print out the mdr file or do you want to print out the address assignment? If you just want to have a printout in which admin boundaries an element lies you can use the mkgmap logger. Add the line uk.me.parabola.mkgmap.reader.osm.LocationHook.results.level=FINE to your logging.properties file.
