<div dir="ltr">Hi,
<div><br>
</div>
<div>thanks for this idea. If I understand correctly, this would mean creating two source tilesets and then generate a third one, where I call mapcache wms requesting these two layers.</div>
<div><br>
</div>
<div>I'll give that a try. Cheers, Michael</div>

In this example foo and bar are the individual tilesets to be merged<br>

<div>Dear Mapcachers, <br>
<br>
</div>
the documentation of mapcache mentions the possibility to merge "multiple tiles into a single image". I wonder if this means a vertical merging (stacking) of tiles into one output tile?
<br>
<br>
This would be exactly what I'm looking for, but so far I couldn't find a hint how this could be done. It would require, I guess, to use multiple sources for one tileset. Is that possible?<br>
<br>
</div>
Thanks, Michael<span><font color="#888888"><br>
