[mapserver-users] Styling (classes) based on zoom/extent?

[Rahkonen Jukka]

Hi,

Visibility by scale is controlled with MAXSCALEDENOM and MINSCALEDENOM at LAYER level. Pretty easy. I am never trying to calculate at which scale the change happens, it is much faster just to try and check the behaviour with a WMS client. For example, for rendering a layer between nominal scales 1:100000 and 1:1000000 use
LAYER
...
    MAXSCALEDENOM 1000000
    MINSCALEDENOM 100000
...
