As you may be aware, both of these are already available using the
FlAniS applet (see
<http://www.ssec.wisc.edu/flanis/examples/flanist10.html>). Of
course, you have to generate the images first and provide a suitable
colortable, complete with "calibration" information.
One of the conceptual hurdles here is that the IDV display is
displaying the actual data [via the VisAD library] and not just an
image (gif, jpg, png, etc), so the "probe" is simply looking at the
display (data) values. That's why the FlAniS example, above, needs a
"calibration" table. If one wants to display the data, it means that
the values must be delivered to the "applet" (I'm using that term to
be an application that runs in a web browser -- now often called a
"web-app" or "WebApp") for display and probing. It also means that
the web-app needs to have all the rendering code (plot values,
contours, filling, surfaces, etc.) built in.

I'm not even sure why people still use the flat-map displays ;-)
