<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/>
