Hi Cindy,

I demonstrated just that on MUM2. See:

http://e41.yellow.sara.nl/mum2/001.html

The example is at the end; please click the "next" button top right 
until you see "Example 6: Two Maps". It's seven lines of HTML and ten 
lines of Javascript. No frames. When you click on the title "Example 6", 
you'll get a running example with two world maps (elevation and 
satellite), that can be zoomed in independentaly. Note that the maps are 
quite detailed: you can zoom in to 1 km.

To use it you have to include my "mapclient_light" JavaScript library, 
about 350 lines of source code. Download it from

http://e41.yellow.sara.nl/mum2/mapclient_light.zip

You don't need to look into the code; just use the ten or so calls on 
the last-but-one page of the presentation.

I have not used it for querying yet. In principle, the whole MapServer 
CGI interface can be called from this library, but queries could take 
some thought. Let me know if you can do something with it!
