Carl,

I think you might be talking about what we are doing on our site
http://geomoose.lyonco.org

If so the configuration could look like this:

....
<map-source name="StandardBackground" type="mapserver" reference="false">
	<file>./Background/StandardBackground.map</file>
	<layer name="all"/>
</map-source>
....
<catalog>
	<layer title="Standard Background" src="StandardBackground/all"
status="on"/>
</catalog>

###
Your mapfile could look like this:


LAYER
	NAME WFS1
	MINSCALEDENOM 30000
	#MAXSCALEDENOM
	...
END #LAYER
LAYER
	NAME WFS2
	MINSCALEDENOM 15000
	MAXSCALEDENOM 30000
	...
END #LAYER
LAYER
	NAME WFS3
	#MINSCALEDENOM
	MAXSCALEDENOM 15000
	...
END #LAYER

Hi Bobb,

thanks, I have stuck the data all into one file and have the
maxscaledenom/minscaledenom values set in the mapfile and that all seems to
work fine.

The bit I am struggling with is the map book set up in geomoose, I need to
simply have one catalog entry for all of the layers so that the user only
sees a single layer in the catalog called  say "Background".

When this background layer is switched on I need the user to see whichever
of the raster layers is most appropriate for the level of zoom they
have....so that the users do not need to know different layers are set up
for different scales the system does the switching for them.

Does that make sense?

I set up the mapsource as a single wms source and used "all" to simply bring
in all of the four layers (not naming each one) I think I need to do a
catalog entry in the map book like this:

<catalog>
<layer title="background" src="mywmsservice/all" status="on" fade="true"
unfade="true"/>
</catalog>

But I dont think this is going to work, in fact having tried it it doesnt
seem to ...or is that just me.

Carl
