<div>Hi Gerd,</div>
<div> </div>
<div>yes I did :-)</div>
<div> </div>
<div>I have tested all those things on two different PCs (both Win10 64bit). Same behaviour on both.</div>
<div>To reproduce it just click into the area of the tile. To find the tile I have made a track around it. Sometimes even this is not necessary and Basecamp crashes without interaction directly after it has loaded the map - maybe 5sec later.</div>
<div> </div>
<div>I have attached the osm-File and a track (kml-file) around it.</div>
<div> </div>
<div>Regards</div>

<div name="quoted-content">Hi Gert,<br/>
<br/>
one more hint: Basecamp crashes in a method "GetDemElevationFromMapCache", so it seems to try to read cached data which doesn't exist.<br/>
Did you try to clear the cache? (press Ctrl+G two times)<br/>

Hi Gerd, Thomas,<br/>
<br/>
I've changed my splitting to handle your hints. But it didn't help so far. Maybe I did something wrong. I will check again.<br/>
<br/>
But I didn't noticed yesterday that the tile is empty. As said my tiles contain contourlines. And with my splitting I get some tiles which are empty. They are somewhere in the ocean. The original tile was larger and covered a part of the continent. So there would be some contourlines. But after my manual split I've got a tile which hasn't.<br/>
<br/>
I have found some more tiles which make problems in my map. And all of them are empty or contain just contourlines with elevation=0 and elevation=0 is not rendered in my style.<br/>
Here one example in .osm-format (converted with osmosis from pbf to osm format)<br/>
<br/>
<?xml version='1.0' encoding='UTF-8'?><br/>
<osm version="0.6" generator="Osmosis 0.43.1"><br/>
<bounds minlon="-10.67871" minlat="44.20898" maxlon="-2.59277" maxlat="45.00000" origin="0.43.1"/><br/>
</osm><br/>
<br/>
I've made a cross check with a tile which contains just contourlines with elevation=0. I changed one line (way) to elevation=50 and now this tile runs fine in Basecamp.<br/>
<br/>
Is it a known problem that Basecamp crashes with empty tiles or at least with empty "contourlines tiles"?<br/>
Does mkgmap report an error or warning if it builds an empty tile? I didn't see such messages.<br/>
<br/>
Here the error message from Basecamp:<br/>

Hi Gert,<br/>
<br/>
normally splitter uses Garmin units, the log shows e.g.<br/>
Map is being split for resolution 13:<br/>
- area boundaries are aligned to 0x800 map units (0.0439453125 degrees)<br/>
- areas are multiples of 0x800 map units wide and high<br/>
<br/>
So, if you force a split at other boundaries this might cause problems, at least with routing.<br/>
I suggest to post a link to the special tile for detailed analysis.<br/>
<br/>
ciao,<br/>
Gerd<br/>

Betreff: [mkgmap-dev] Basecamp crashes with my map<br/>
<br/>
Hi all,<br/>
<br/>
I've a question about splitting a map.<br/>
<br/>
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.<br/>
<br/>
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.<br/>
<br/>
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.<br/>
<br/>
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 :-)<br/>
<br/>
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.<br/>
<br/>
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.<br/>
Could one ot those questions lead to that behaviour?<br/>
<br/>
Do you have another idea what could be wrong with a tile that crashes Basecamp. Or do you have an idea what to check?<br/>
The map is working well on different Garmin devices (Oregon, etrex hcx).<br/>
<br/>
Many thanks for your support.<br/>
<br/>
Best regards,<br/>
Gert<br/>
