MINSCALE MAXSCALE USE in grouped layers

[Gregory Yetman]

Hi Glen,

I had issues with this setting up a series of image layers as well. 
MINSCALE is the largest scale that the layer will be rendered at, 
MAXSCALE is the smallest scale that it will be rendered at. This is a 
bit confusing if you are used to cartographic conventions (i.e., 
MINSCALE would be the smallest scale). There was a good post by Ed 
McNierney on how the scale is calculated based on the display at little 
while ago, it helped us calculate what scales to use (a belated thanks 
to Ed). Ed's posts are available at:
