Hi Nick, I use max-nodes=100 000, not 10 000, but you may be right that this is important. I'll try again with realistic values.

Hi Nick,
I tried --align-for-dem=360 with your --dem-dists=2484,3312,9942,16560 and my dem-poly and it always crashes :-(
It always seems to work with only one of the values, e.g. --dem-dists=2484 or --dem-dists=3312 or --dem-dists=16560
So, it seems that I was wrong when I thought that the code behind the "Show Profile..." button would ignore all but the highest resolution.

Hi Gerd
Just noticed your crash.gdb , which indeed causes a crash
However, if I take a different starting point but still join the a39 where your route joins it , I don't get a crash,
Very odd that the end sames ok but the beginning.
Anyway, will do some more checking tomorrow

Hi Gerd
I can see that , but again no probs here when I used your map
For my final trial i used some pbf files of the UK which were split last year without the align for dem option
This still worked !, ie no crashes ;
good point - have to check if the dem poly includes empty hgt files.
Will do some more checking tomorrow.
Again, congratulations on a major achievement!

Hi Nick,
okay, sounds good. Do you also use -dem-poly or hgt files with voids? I tested a rather small polygon [1] divided into 10 parts, maybe that created more stress for MapSource.
Maybe we can find other --align-for-dem values or -even better - a field in TRE or DEM or TDB that can be changed to allow more or all values.

Hi Gerd,
Having difficulty creating long distances without stopovers ikn Mapsource, but that seems have been the case anyway before dem, at least in my case using default style
Have created a long distance one in Basecamp, exported it in Mapsource and absolutely no problem with creating profiles! Excellent work !
If I invert the route , ie in Basecamp, and export it in mapsource, same : no issues at all
At one stage, I cannot reproduce it ,I just got a black profile, but that could be when I a dem was missing.

Hi Nick,
great! In my test cases I found problems with long distance routes without any stopover. Please try that as well, maybe also the inverse routes.

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

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.

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?

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
