Re: [udig-devel] netcdf in catalog view

You can provide a description of the dimensions and so on of the layer
as part of its description (or even title).

The handling of the different sliders in the navigation model should
be pretty easy ...
just like we layers that do not have a sense of time (say a base tile
server layer) will not respond as time changes; layers that do not
have height would remain unchanged if you changed the heigh; or layers
that do not understand pressure would remain unchanged if you messed
around with pressure.

Note: the other way to handle this stuff is as a "style" setting; and
there should be some kind of guideline of when a style should be used;
or when part of the viewport model should be used...

I am hoping to learn more when we have some data to poke away at.
