[mkgmap-dev] [PATCH] POI Address Support, Country Region Autofill v5

Tue Feb 10 20:27:06 GMT 2009

Hello,

here is v5 of my patch. Changes since last release are:

- Code cleanup
- Add option --pois-addresses to switch on the filling of POI address 
information

By default the address information is no longer added to the pois. Also 
the filling is very conservative now and is not doing to much guessing. 
I think in most countries this default is useful to minimize the risk of 
wrong information. All POIs that have incomplete address info are marked 
with "Fix me address" as street name. In countries with good is_in info 
coverage I would suggest to use this options:

--pois-addresses --location-autofill=1

I think I'm pretty done for now. What do you guys think about 
integration of my stuff ?

Thanks
Berni.
