Each layer contains different features and each is styled so that a particular
featured is rendered differently based on a scale within that layer. For
example there may be a feature on one layer that represents an object. At one
scale it will be rendered as a mark e.g. triangle, but then it may be rendered
as an external image at a closer zoom.
The issue is that certain layers have features that are more important than
others and all are drawn at the same time.

Subject: Re: [Geoserver-users] Z-Order Question
Are these bound by scale, ie medium resolution between a certain scale range,
or do you want to draw all layers at the same time, overlapping?

Hello list,
I'm a bit confused on something and I was hoping someone can point me in the
right direction.
Firstly background; I'm using the CSS module for my styling and I have several
layers on my map that add more detail as the user zooms in.
I need to be able to control the z order of the marks/symbols being used. I can
see that there is a CSS z-order parameter for labels but is there an equivalent
for the symbols?
Example; if I had 3 layers called LowDetail, MediumDetail and HighDetail how
could I ensure that a certain point symbol introduced in MediumDetail was
always drawn last and therefore always visible?
Thanks
Chris
