[mkgmap-dev] polygon-size-limit inside polygons file - large work to implement?

Wed Jul 10 19:13:20 BST 2013

what's the difference?

The polygon size limit is not m² but garmin units. So it should be fine 
too, or not? Does it matter so much, that extreme North/South this is 
different (I don't even know if it is).
length filter is great, but not so fast (dunno if that is only if you 
use it in conjuction with routes), and there was no option. The 
polygon-size filter already exists - so it would merely be specifying it 
further (without any speed reductions I would believe).

Or because m² is easier to setup? I'm not sure - if there are any 
benefits. One would need to play around a bit with it anyhow, to find 
out sensible values. So be it Garmin units, or metric units, doesn't 
make a difference for me.
