I find it hard to believe they wrote it all in IDL! I'm guessing its
probably scriptable in IDL, but underneath its written in something
else... I could be wrong though!

I clicked on 'Product Documentation' on the ENVI site and it wanted me
to log in or create a new user. To see the documentation? To find out
what the program is about?
Oh, what I really wanted was the Feature Tour..

Last year I looked at GIS-R linkages, with the added criteria of being
open source and cross-platform. There are now a few free GIS packages
that can do this kind of thing, with a little added glue.
I settled on OpenEV - it has vector and raster support, its extensible
in Python and uses Gtk for dialogs which you can customise. All I needed
was to get Python talking to R, so I wrote some Python bindings to
Rserve. Now I've got a GIS with a menu that drops down, you choose the
point layers you want to work on, click 'Go', and R does some analysis
that ends up as a raster layer back in the GIS. The user doesnt care
that R did it.
Other GIS solutions are available!
