<body class='hmmessage'><div dir='ltr'>Hi,<br><br>I think the problem is that we need a process that compares two <br>sets of precompiled boundaries (we have that) and decides which one<br>is better (I think we don't have that).<br>The BoundaryDiff tool comes close to what we need. It computes the <br>differences between two sets and creates gpx files.<br>Sample usage:<br>java -Xmx2G -cp mkgmap.jar uk.me.parabola.mkgmap.reader.osm.boundary.BoundaryDiff bounds_20121118.zip bounds admin_level=2<br>The problem - besides the huge amount of data and cpu usage - is this: How do we find out which difference is good and is bad? <br><br>A different approach:<br>If we find an area that is covered by a level 4 boundary, but is not part of a level 2 boundary,<br>something is probably wrong. Or more general, if we subtract the combined area for level n+1<br>from the combined area for level n the result should be empty.<br><br>Gerd<br><br><br><div>> Date: Fri, 24 Jan 2014 10:52:35 +0100<br>> From: kukuk@suse.de<br>> To: mkgmap-dev@lists.mkgmap.org.uk<br>> Subject: Re: [mkgmap-dev] boundary France broken?<br>> <br>> <br>> Hi,<br>> <br>> On Fri, Jan 24, WanMil wrote:<br>> <br>> > I think we can add such a link.<br>> ><br>> > Anyhow is there anybody who has some server capacity and is able to update <br>> > the bounds and sea files regularly?<br>> <br>> For my own usage I create bounds files regular once a week<br>> and daily sea files.<br>> <br>> Webspace is not a problem, too.<br>> sea data is about 140m for me currently, that's not the problem.<br>> The bound files are about 1GB.
