<p>Hi Patrik,</p>
<p><br>
</p>
<p>good question. I also wondered if splitter can be changed to ignore wrong bounds</p>
<p>tags. My thoughts:<br>
</p>
<p>In your case the bbox is far too large, means it claims to contain data that is not there.</p>
<p>The normal case is vice versa: The file contains some nodes outside of the bbox,
<br>
</p>
<p>maybe from ferry lines or other long ways, and my understanding is that we don't</p>
<p>want to calculate the tiles based on those few nodes, since we might get a map with</p>
<p>larger empty areas at the "border". No idea if that would cause more trouble. <br>
</p>
<p>With typical data from geofabrik and the --no-trim option there will always be large
<br>
</p>
<p>empty areas as most countries are not rectangular ;-)</p>
<p><br>
</p>
<p>Possible changes in the code:</p>
<p>1) add a --ignore-osm-bounds option and set the default to false (means one gets </p>
<p>the same result like now when he uses the default)<br>
</p>
<p>2) add a --use-osm-bounds option and set the default to false</p>
<p>(means one might get a different result when using the default)<br>
</p>
<p>3) add code to check how the collected data matches the given bounds, <br>
</p>
<p>use whatever is smaller. This might also be triggered by an option if needed.<br>
</p>
<p><br>
</p>
<p>I'd like to get some feedback from others first.<br>

I couldn't go to sleep without getting to the ground of this... <br>
<br>
I performed the following tests on linux, always with my standard --no-trim present:<br>
<ul>
<li>original osm.pbf file downloaded from geofabrik (with the problematic bounds tag in it)<br>
-> FAILURE </li><li>converted with the help of osmconvert to normal osm format<br>
-> FAILURE (which was to be expected, same file, just different format) </li><li>deleted the osm tag with a simple command like 'cat file.osm | grep -v bounds > file-nobounds.osm' and ran splitter against it, always with the same options<br>
-> SUCCESS </li></ul>
<p>This leads me to the question why the bounds tag is read/used if it also works without and even gives less problem ?<br>
</p>
<p><br>
.... sorry for bombarding you (and the list), but I think it's nevertheless and interesting question.<br>
</p>
<p><br>
Cheers<br>

I did dig a bit deeper... also as it rang a bell:<br>
we had quite a similar problem with the wrong bounding box in Alaska already October 2014. It was an illegal value of maxlon="180.0005" causing splitter to bail out<br>
<br>
When I convert the osm.pbf file with the help of osmconvert to osm and look at the first few lines I see a 'bounds' tag announcing the problematic bounding box (not illegal as in 2014, but still 'suboptimal'):<br>
<blockquote><tt><?xml version='1.0' encoding='UTF-8'?></tt><tt><br>
</tt><tt><osm version="0.6" generator="osmconvert 0.8.2" timestamp="2016-03-23T20:13:02Z"></tt><tt><br>
</tt><tt> <bounds minlat="49.8089" minlon="-179.9532" maxlat="73.79794" maxlon="179.9999"/></tt><tt><br>
</tt><tt> <node id="27207079" lat="64.7487541" lon="-147.3242821" version="2"
</tt><tt><br>
...</tt><br>
</blockquote>
<br>
Getting the statistics via osmconvert with --out-statistics seems to read through the file and checks the 'real' bounding box:<br>
<blockquote>...<br>
<tt>lon min: -180.0000000</tt><br>
<tt></tt><tt>lon max: -122.5122525</tt><br>
<tt></tt><tt>lat min: 48.6234931</tt><br>
<tt></tt><tt>lat max: 71.6061501</tt><br>
<tt></tt>...<br>
</blockquote>
<br>
I'm now wondering if splitter get's confused by the existing but obviously strange bounds tag.
<br>
<br>
According to the findings in 2014 splitter can handle files without the bounds tag and just gets the real boundings from all the elements in the file.<br>
I did not test to run it through splitter without the bounds tag as I'm having troubles converting the file properly on my windows... but I'll try that probably tomorrow again on linux (sort of late already today).<br>
The process would be<br>
<blockquote>osm.pbf -> osm -> get rid of the bounds tag -> back to osm.pbf again (to have same source file format)<br>
.... and then run the splitter and see what happens.<br>
</blockquote>
But if I have a proper osm file with the 'problematic' bounds tag in it, I can also try to reproduce the problem with the osm file. If it is reproducible I just drop the tag and try it again.<br>
<br>
BTW: I've contacted geofabrik already via email<br>

Sorry, your explanations came in during I was writing up the test results ...<br>
<br>
Think it's all clear so far.<br>
<br>
As we're creating lot of different maps I'm just wondering if I can/should drop the option --no-trim for all map building or if I would suddenly run into other/new problems...<br>
<br>
I'll contact geofabrik with the details.<br>
<br>
Many thanks and happy Easter.<br>

Yes, alaska.osm.pbf is small.<br>
<br>
It works without --no-trim. And it also works with the polygon file that belongs to alaska.osm.pbf (also downloaded from Geofabrik) which, according to documentation, anyway would disable --no-trim option.<br>
<br>
Do you still need the resulting densities-out of the failure ? It's about 700 kb... if yes, how should I provide it ? Just attach it here ?<br>
<br>
You have to excuse my question, I'm not the crack: is this now a problem of the pbf file, or the splitter ? ... or just the way I try to use it ?<br>
<br>
Thanks already now for your help.<br>

<div>Hello together,<br>
<br>
I'm running into a problem with the splitter (r435 aswell as r427) when splitting the US_ALASKA file downloadable from Geofabrik.<br>
<br>
The exception is:<br>
<blockquote><tt>Warning: No solution found for partition (49.7900390625,-179.9560546875) to (73.828125,180.0) with 6'702'717 nodes</tt><br>

<br>
The complete command line with the splitter call is:<br>

<br>
The pbf source file comes from:<br>

Interesting to mention:<br>
- splitter exception mentiones a complete different coverage area than osmconvert statistics.<br>
- the area is near -180 / +180... always complicated.<br>
<br>
Do I miss something ? All other pbf's I've tried are splitting properly without any problems. Do I need to change something in the arguments ? Or is it a simple problem of the actual pbf file ?<br>
<br>
Any ideas are very welcome....<br>
<br>
