Some of the new features, including SLD import/export, are pretty interesting. gvSIG seems to be flourishing a bit under the wing of OSGEO. It’s a tool that I have gone back to periodically over the years, and I’ll probably take a deeper dive this time given some of the new features. I suggest giving gvSIG a go if you haven’t tried it.
UPDATE: The gvSIG download site seems to be having some serious bandwidth issues.
