Hi all,

I've created patches for splitter and mkgmap.
The binaries are here:
 http://files.mkgmap.org.uk/download/417/splitter.jar
http://files.mkgmap.org.uk/detail/416

Please try splitter with align-for-dem=360. I found no more crashes as long
as used only one dem level, e.g. dem-dists=3312 or dem-dists=9936

Maybe you find a combination of  align-for-dem and dem-dists with more than one 
value
that still works, I'll try again tomorrow.

Gerd

Betreff: Re: [mkgmap-dev] patch for crash in MapSource

Hi all,

the patch contained a stupid bug, but there is more to this:
1) the effect of the patch depends on the dem-dists value (I assume only the one
that gives the highest resolution). The higher the resolution the better it 
works.
2) it probably also depends on the boundaries (areas.list)

I assume now that the tile boundary from areas.list should be a certain 
multiples of degrees,
probably different multiples for lat and lon and that the overlap simply makes
sure that this boundary is within the overlapped area.
Maybe the preferred multiples also depend on the dem-dist.

I'll try to find out more ...

Gerd

Hi Gerd

I think you are right ,ie

start and finishing point  at same level seems OK eventhough the route
turns south 20miles then up again
