[mkgmap-dev] Multiple Relations and Admin levels

Fri Aug 6 02:01:39 BST 2010

Hi WanMil,

Without the --process-boundary-relations I don't get a number of national
parks that I imported to OSM for South Australia. These needed to be
relations due to there size and a number of them had multiple looped ways.

The problem also seems to be there from the maps supplied from
http://garmin.na1400.info/routable.php

They also now use the --process-boundary-relations as I pointed out that
this option was new and now appears it is needed for relations. 

I mentioned this after other users were missing boundaries that were there
before the option was added.

Regards,

Markus_g

Hi Markus,

I have no time now to check that in deep (will do that later).

Do you really need the --process-boundary-relations option? Without this 
option multipolygon boundary relations are not processed. I think you 
only need that in case you have some polygon rules for boundaries in 
your style file but there aren't some in the default style.
I guess removing that option could fix your problem.

Have fun!
