[mkgmap-dev] [PATCH] --ignore-builtin-relations

Thu Aug 25 20:09:21 BST 2011

Marko,

I do not like that very much because relations are now a very common 
element of OSM and you need to know in detail what you are doing if you 
set this option. From my point of view it makes sense only if the 
polygons file of the style file is empty. So why do we need the option? 
What about adding a simple check if the polygons style file is empty?

Anyhow I would change the name of the tag to --ignore-relations. That's 
what the patch is doing (as far as I understand): do nothing with relations.
