[mkgmap-dev] [PATCH] POI Address Support, Country Region Autofill

Sun Feb 8 12:31:41 GMT 2009

Hello,

here comes version 4 of my patch. I have added a option to control the 
new feature. By default only reliable address info is used:

--location-autofill=''number''
    Controls how country region info is gathered for cities / streets 
and pois

   0    (Default) Info of nearest city is taken. The country region  
info is gathered by analysis of the cities is_in tags.
          If no country region info is present the given default country 
region is used.
    1    Additional analysis of partial is_in info to get relations 
between hamlets and cities
    2    Brute force search for nearest city with info if all methods 
before failed. WARNING:
          Cities my end up in the wrong country/region.
    3    Enables debug output about suspicious relations that might 
cause wrong country region info

Thanks
Berni.

>> - Country Region Autofill for Marks recently added find-by-name function
>> - POI simple and complex house number and phone number support
>> - POI address info is taken from "Karlsruhe address" info if available
>> - Phone support is pretty cool if you have a garmin that support cell
