Analisa,
I would add that Thuban (http://thuban.intevation.de) is a good
candidate for an easy to use thematic GIS viewer that can be
pretty easily extended and customized in Python.
I believe that UDIG isn't mature enough for near term inclusion though
I did get an impressive demonstration of it recently. OpenEV is only
so-so as a vector gis viewer, though it has what I think are some great
raster capabilities. I am embarrassed to admit I haven't actually run
QGIS yet myself though I hear lots of good things about it.
You will obviously have to play with the various packages, but if you
want to customize it somewhat to provide canned views, or special
hooks into some of your auxilary reports your decision will likely be
substantially influenced by your comfort with various customization
mechanisms.
OpenEV and Thuban are Python based for instance, while JUMP is
Java code and QGIS would have to be extended in C++ (I think).
You just mention viewing and exploring the data, but are you also
interested in folks being able to print, or translate the data into other
formats? One thing that I think is quite valuable in "data+viewer"
CDs is including the ability in the viewer app to export the datasets
in a variety of formats. Depending on your target audience, you
might want to think about that.
Best regards,
