[mkgmap-dev] splitter and josm problem

Sat Apr 1 16:02:51 BST 2017

Hi Thomas,

I've changed splitter to print better information about the overlapping areas, please try r583,
it is now also able to parse the file http://img2ms.de/bilder/areasEuropa.list
With r583 I see these messages for that file:
...
Waring: The areas given in --split-file are overlapping.
overlapping areas 50000002 and 50000751 : (2848768,-1536000 to 3788800,-868352) and (2482176,-1536000 to 3149533,-868352)
overlapping areas 50000353 and 50000786 : (2125824,671744 to 2125825,727040) and (2125824,671744 to 2164736,727040)
overlapping areas 50000657 and 50000658 : (2478080,671744 to 2544552,727074) and (2428928,727040 to 2490368,819200)

....
(the first one is a huge overlap)
It doesn't report 50000707, so I assume that you are looking at old data in that case.

Besides that overlaps are not forbidden by splitter, you just have to make sure that you don't put overlapping areas
into the same gmapsupp as that will cause routing problems.

Hi Thomas,

splitter r580 cannot read this file without a few small changes (blanks added/removed).
After these changes it complains that there are overlaps.
Seems you are using a different file or a different program.

I have controled my areasEuropa.list (download
:img2ms.de/bilder/areasEuropa.list). I found no overlapping around the
50000707. All neighbours 50000705; 50000709; 50000728; 50000729;
50000708 ;50000706; 50000705) have identical borders without any
overlapping. Or shout it have a overlapping ? how many Garmin-units ?

But splitterr-580  do not proper splitt the multipolygon ("Schloßteich", 3 Elemente) [Kennung: 59.766] . The mp has tags: name=Schloßteich; natural=water, type=multipolygon. This mp has element Rolle=outer; 23387723 (86 Punkte) [Kennung : 23.387.723]. The error ist : all 86 nodes has no tags , but it should have the tags natural=water and name= Schloßteich from the multipolygon. See picture : img2ms.de/bilder/wrongsplit.jpg
