[mkgmap-dev] Maximum map resolutions people use

From Chris Miller chris.miller at kbcfp.com on Sat Aug 29 09:48:14 BST 2009

I'm looking into building a density map to help improve the splitting (whether 
the splitting be automated or done via a GUI tool), and I'm trying to get 
a feel for what the memory and disk overhead will be using this approach.

In particular, I'm interested in finding out what the highest number is that 
people are using for the --resolution parameter in the splitter. Is anyone 
using a value of 20 or higher? If so, what is the bounding box of the osm 
file that you are splitting? eg Europe's bounding box is (34.43055,-31.78259) 
- (82.35188,69.41235) while the whole planet file's bounding box is (-90,-180) 
- (90,180).

If you're unable to view the start of the osm file due to its size or because 
it's compressed or whatever, just let me know which osm file it is and I'll 
figure it out from there.

Many thanks,
Chris
