Hi Dom,
That's looking nice :) Guess we'd better get a WCS working so people
can do proper downloads!

There are some nice features evolving, you can now easily load WMSs from other
servers into the client. I have preloaded the server with a few WMS endpoints
to try out - 2 from BADC, 1 from PML (using NcWMS) and 1 from Metacarta.com.
In a brilliant bit of timing, our server fell over ;) Happily, that let
me test what happens if the server is dead - it might be worth adding
something that lets people see the server isn't responding in a
reasonable time.
Note there are still interoperability issues to iron out - such as PML's map
legends are vertical whereas the client expects horizontal, but these things
are steadily getting ironed out - and are likely to be part of the OGC Met
domain working group's remit in the near future.
Interesting point on the vertical legends - I don't think we've actually
used those as yet so I guess that's what's coming out of ncWMS by
default. It generates those on the fly afaik.
There are also some interesting extensions with ncWMS for the WMS part -
I see you got the palette selection, which is great (although the legend
didn't update when I switched to greyscale, for example - you might be
missing a parameter there). There's also an extension to do logarithmic
scaling, which is very useful for the chlorophyll data. Depending on
how you handle different servers, it may be better to wait for the OGC
to incorporate these sort of styling options.
