[mkgmap-dev] merge-lines and routing

Fri May 3 09:20:39 BST 2013

Hi WanMil,

okay, this will be a big change that requires a branch. So, for now, 
I'd like to finish the merge-lines issue.
Attached is version 2 of the patch that allows merging lines at all resolutuions
except for roads on res 24.

Some numbers for a map of niedersachsen with default style and lots of enabled features:
(seconds run time,  gmapsupp.img size in bytes)
r2581 with merge-lines: 99s, 127.567.872 
r2581 with no-merge-lines: 103s, 128.182.272
patched r2585 with merge-lines: 95s, 125.599.744 
patched r2585 with no-merge-lines: like r2581

I see no good reason why merge-lines is an option. I think we should enable
it and remove the parm, or at least, make merge-lines the default and allow
to switch it off with --no-merge-lines.

Compiled binary is here:
