Re: [mapserver-users] How to assemble mapcache tilesets into a new layer?

2020-02-13 Thread jbo-ads 
Yes your configuration looks right. 

But IIRC, if you want to use that source, you actually need to define a tileset 
that references it. Something like: 

 
/path/to/cache/D.sqlite3 
 
 
D 
D 
... 
 

and use it as: http://localhost/mapcache?REQUEST=GetMap=D;.. .

Ok to answer my own question, yes you need  section like this for 
assembly to work: 

 
 
 
image/png> 
A,B,C 
 
 
 
http://localhost/mapcache 
 
 

And you don't need a  defined for it to work as it reads data 
from the existing tilesets and assembles the new image. I suppose if you 
wanted you could also define a new tileset so it would cache the 
assembled images, but I'm not sure that that is needed except possibly 
in very high demand situations. But this is just my surmise. 

Thanks,

Assembling several layers can be performed with a WMS request using 
"...=A,B,C&...". Then to create a new layer, you just need to 
define a WMS source using that WMS pattern.

Jérome,

Thanks that seems simple enough. A couple of questions:


  
    
  image/png>
  A,B,C
    
  
  
    ?
  



  D
  ...


Does this look right?
Should I have an  section and what should be in that if anything 
for assembly of existing tilesets?


Thanks,

Hi all,

I have three existing layers in my mapcache.xml and I need to create 
a new layer that assembles this three layers into a single layer. 
There is a section in the mapcache documentation 
https://mapserver.org/mapcache/tile_assembling.html but it is not 
very helpful ;)


Can anyone help with with this problem?

Say I have existing tilesets "A", "B", "C" how would I create a 
tileset "D" where it stacks A, B, and C like:


C
B
A
