[mkgmap-dev] Finding administrative areas

Tue Aug 7 13:40:18 BST 2012

I have been unable to make this work. I have copied all the admin_level 
rules from the default style files into my style, and introduced 
pre-compiled bounds. Using mkgmap r2130 and Wanmil's sample rule (as 
below),  I always get a java exception (below). I have tried various 
variants on the rule and various data sets, with no differences.

Advice welcomed!

Thanks,

Roger
