[mkgmap-dev] Subdivision width is 36627 at 3230916/1236133

Sun Apr 22 20:34:03 BST 2012

Hi Marko,

I think the problem is not at all related to the objects near
3230916/1236133.
This is just the middle of an area which is too large. I am not sure why it
is too large,
but I guess the reason could be that it is so empty.
The intended width is 36627, the maximum value is 32767.
I assume the effect of this warning is that something is missing on the
side(s) of the
intended area.

I do not yet understand the details of the map creation process, so I can't
say more 
for now. I'll try to find out, but maybe someone else knows more?
