[mapserver-users] Hiding overviews

[Eichner, Andreas - SID-NLK]

Hello everybody!

I've build external overviews, both with raster and vector data, put
them into layers with MIN-/MAXSCALE and it works like a charme. My only
problem is that I can not get the switching of those layers transparent
to the user. A "GetCapabilities"-WMS-Request returns all layers
separately. But it makes no sense for the user to turn only one layer
on/off. Instead the only useful thing a user can do is switching the
hole _group_ of detail/overview layers on/off.
So is there a way to only show the hole group as _one_ single layer in a
WMS with mapserver? The WMS specs (v1.3.0) suggests that only the group
layer should have a name, the single detail/overview layers should not.
Therefore only the group layer can be contained in a WMS request and
should be shown by a WMS client as one single layer, I think.

It would be nice to make external overviews appear as transparent as
GeoTIFF's internal overviews... Any tipps, suggestions, help?

Thanks a lot!
