[mapserver-users] problems defining outline width using min/max

[Fawcett, David (MPCA)]

Dara,

Take a look at SYMBOLSCALEDENOM in the LAYER block.  This defines the scale at which the line appears 'normal' sized.  You may also need to define a WIDTH in the style.

For the value in SYMBOLSCALEDENOM, if you want this scale to be 1:10,000 the value would be 10000.  Since scales in Web maps are somewhat relative, you will likely take a good guess at a value and then experiment with how it is rendered and tweak the value if needed.

David.

Subject: [mapserver-users] problems defining outline width using min/max

Greetings.
We are using MapServer 5.2.1 and I am having some problems with defining a polygon outline.  I would like the polygon outline to have widths so that when you zoom in it stays wide, but is not too wide when you are zoomed all the way out.  I thought I might be able to do this with min/max widths (see below), but it does not seem to change compared to if I just have the width defined as 2.2.  Is there a way to do this?  Should I be using something other than pixels or should I group into min/max scales?  Any help would be greatly appreciated.
Dara
