<div>Hi all,</div>
<div> </div>
<div>I've a question about splitting a map.</div>
<div> </div>
<div>I'm using splitter to split a large pbf-file with
contourlines to about 300 tiles. This works fine. But now I
have the requirement to support a process<br>
with two parts of the whole map, splitted exactly at a given
latitude. So I've written a simple tool that reads the
tile-list from splitter ( --write-kml),<br>
searches for the tiles which are north or south of the given
latitude and writes them to a file. For the tiles which are
divided by the given<br>
latitude the tool divides the tile in two parts and writes
the parts as new tiles to the file.</div>
<div> </div>
<div>As the next step splitter is called again with the file
as a parameter (--split-file) and mkgmap is used to create
the two maps.<br>
All this works wonderful, but yesterday I've seen that
Basecamp crashes when I install those tiles.</div>
<div> </div>
<div>I'm doing this since several years now, but never noticed
that behaviour. Maybe I didn't see it, because I'm not using
Basecamp very often.</div>
<div> </div>
<div>So today I spent some hours to look deeper into that
problem. I could eliminate one tile. Then I noticed that
size of this tile is just about 8 kB.<br>
And when I deleted the tile from the map Basecamp doesn't
crash anymore. Of course the map should have a hole now :-)</div>
<div> </div>
<div>Ok, so far so good, but what's the reason for that
behaviour. This tile was splitted by my tool. So maybe I'm
doing something wrong.<br>
But I have splitted a lot more tiles which seem to work.</div>
<div> </div>
<div>So I have some questions:<br>
1) I'm splitting the tiles into two parts, at full or half
degrees, e,g. 47.00000 or 47.50000.<br>
2) The mentioned tile is less than 1 degree in north to
south direction.</div>
<div>Could one ot those questions lead to that behaviour?</div>
<div> </div>
<div>Do you have another idea what could be wrong with a tile
that crashes Basecamp. Or do you have an idea what to
check? </div>
<div>The map is working well on different Garmin devices
(Oregon, etrex hcx).</div>
<div> </div>
<div>Many thanks for your support.</div>
<div> </div>
<div>Best regards,<br>
Gert</div>
