Hi, I've been working on Gtk2::Ex::Geo modules, where a central 
functionality is to display geospatial data.

Surely the lowest level of making the images is fastest done with C or 
perhaps C++, but I guess in this case the speed of disk and network (are 
those images on a network disk?) and amount of memory (are those images 
to be open at the same time?) are important. But in general I think it 
is very sensible to divide the functionality between Perl and C, it 
makes many things much easier.

'So far I've been looking at only a few images but in near future I 
expect to work with spatio-temporal data and then the number of images 
increases substantially.

I'm a bit puzzled with this. I haven't used gtkmm at all, in fact I had 
to look it up now to see what it is. I've been using simple gdk pixbufs, 
which are easy to make and easy to use in GUI (although the memory 
management took a while to learn). Right now I'm considering starting to 
use Cairo and Cairo objects as the central image.

What kind of functionality do people want from the software? Compare 
images? Overlay them? Zoom in/out? See animations?
