<div class="PlainText">Hi,<br>
<br>
The mapcache docs has a page for vertical assembly but it is blank :(<br>
<br>
I have 7 layers in mapcache and I would like to vertically assemble <br>
these into a composite layer. In the past I have been loading all 7 in <br>
openlayers but it makes more sense to just composite them into a new <br>
layer. There are some scale limits that apply to the various layers.<br>
<br>
Does anyone have some info on how to do this in mapcache directly rather <br>
than create a mapfile and compositing them in mapserver and then making <br>
that a new layer in mapcache.<br>
<br>
Thanks,<br>
-Steve W<br>
