Hi Gerd Brilliant ! have done a really spaghetti route with lots of ups and downs left and right and seems to be working with align-for-dem=360 and even --dem-dists=2484,3312,9942,16560 r Nick On 08/02/2018 17:40, Gerd Petermann wrote:
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

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 ...

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

Hi all,
okay, thanks for testing. I'll try to find a better patch. Please check: I think the patch works fine for routes which cross tile borders in horizontal direction direction but I still see problems with vertical crossing. Can you confirm that?
Gerd

Same for me, but just did quick test. Will try on the weekend more detailed Henning On 8 Feb 2018, at 16:57, lig fietser <ligfietser@hotmail.com<mailto:ligfietser@hotmail.com>> wrote:
Hi Gerd,
I tested your patch but I still see frequent crashes near tile borders.

Hi all,
attached is a patch that seems to help in many cases where --dem-poly causes crashes in MapSource "Show Profile..." A binary is here: http://files.mkgmap.org.uk/download/414/mkgmap.jar
It changes the TRE file and the *.tdb file. I still see a few crashes but maybe those are caused by other problems.
Please try and let me know your results. I found no bad impact so far, long distance routing still seems to work, but I've not tested much.
@Steve: Maybe we have to make sure that the areas in *.tdb do not overlap. In this case this patch is not yet okay.
Gerd
