[Cartoweb-users] 2 mapserver layers as 1 cartoweb layer: possible?

[Jacolin Yves]

Hi,

You can use the REQUIRES parameter as well, e.g.:
LAYER
   NAME   point
   ....
END
 
LAYER
   NAME   line
   STATUS default   # <---------- status default: the layer is ever visible
   REQUIRES "[point]"  # <------ but only if layer "point" is visible too
   ....
END

Reghards,

Y.
