Hi Gerd,

maybe splitter can be modified  similar.

Re: [mkgmap-dev] max-jobs patch

[Henning Scholland]

Hi Gerd,
Hi Mike,

I gave it a try on all my maps (splitted with max-nodes=1.600.000).
Removed xmx and max jobs. mkgmap used all 8 logical cores and about 4GB
of memory. So it seems, Gerd was correct with the 500mb per job. So I
would suggest to limit max-jobs with 32bit java to 3 jobs and to
RAM/500mb on 64bit java. The used jobs should be minimum of both CPU and
RAM.

Regarding to higher amount of RAM I was mentioning before, I was calling
mkgmap with xmx=12G, maybe java is not freeing the heap in that case. It
was during dem-branch. Maybe during that time mkgmap wasn't also that
efficient.

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

[Gerd Petermann]

Hi all,

If I got that right the dem-dist value 9936 means that splitter should create
boundaries with a multiple of 621 map units:
621 * 256 = 158976 = 16 * 9936
This should work fine for 3312, 6624 as well.

It seems that we always see problems when a tile boundary is far away from this.
I assume that Garmin selects all dem-dists values so that there multiples are 
close
to certain values and those values are used to split. The overlap in TRE seems
to allow small differences, but e.g. a split at lat 2424800 never works with
3312,6624 or 9936, and Minkos tiles were split at this lat.

 So, the current patch for splitter doesn't help as it tries to align to 1/360° 
when you
use --align-for-dem=360. 

I still try to find out how many levels we have to align,
maybe only the first and the 2nd are important, maybe all.
I am not yet sure what that means for the split algo.

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!

Re: [mkgmap-dev] Problem with gmapi-builder

Hi Gerd
When mkgmap added --gmapi option I did some test and found that mkgmap 
(without --gmapi)+gmapi-builder was a little faster than mkgmap with 
--gmapi, that's why I continued using gmapi-builder. Perhaps it's time 
to change my toolchain (I alredy did for DEM maps)

Unfortunately your patches don't work for me, I still get crashes crossing tile

Here are two tiles where it happens frequently:

#   : 51.83,4.263897 to 52.030563,4.483323

 I tested a rather small polygon [1] divided into 10 parts, maybe that

 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

 Have created a long distance one in Basecamp, exported it in Mapsource

 At one stage, I cannot reproduce it ,I just got a black profile, but

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

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
