well - anything is better than the current crash. Maybe just a rerun
with "safe" options added?<br>
<br>
Please also look on Antarctica extract by geofabrik. I didn't find
time yet to test it again why it crashed... <br>
<br>
Or is search-limit that option what I am looking for? I so far
didn't know about this new switch at all...<br>

<div dir="ltr">Hi Felix,<br>
<br>
it seems that the default --search-limit is too low for japan
with sea data.<br>
With --search-limit=5000000 I see a very good split after ~30
seconds:<br>
Solution is nice. Can't find a better solution: 86 tile(s). The
smallest node count is 1111027 (92 %), the worst aspect ratio is
near 3.94<br>
<br>
For many other input files, this will just increase run time a
lot.<br>
<br>
I am not very happy with this option. I think I will replace it<br>
with something more useful like<br>
--wanted-fill-ratio=90<br>
which means try to find a solution where the least populated<br>
tile has 90% of max-nodes.<br>
<br>
The problem is that some areas do not allow such a good result,<br>
so I am still looking for good criteria to stop the search,
maybe<br>
I'll use the overall search time in seconds:<br>
--max-search-time=60<br>
would use the best result found after 60 seconds.<br>
<br>
Any other ideas?<br>
<br>

<div dir="ltr">Hi Felix,<br>
<br>
thanks for reporting. I can reproduce the problem. It
disappears when<br>
you remove the --precomp-sea option.<br>
I'll try to find out why.<br>
<br>
> Where is the log saved? Do I need to provide it?
Splitter not fully up <br>
This message is printed to stderr for the case that you
pipe stdout to a file like this:<br>
java -jar splitter .... > splitter.log<br>
