You said for free data that implies that there is better quality out there for sale- yes? any links for them I believe that we would probably consider them if the price was reasonable.

If you are looking into change analysis, the bonus of CCAP is that it's on a 5-year program. CCAP (NLCD) is fine for a level II classification (Anderson), but you'll need better resolution imagery if you want to capture more than ~20 classes.
If you have $$$ then talk to Space Imaging (perhaps I should have added another $). I think they are starting to peddle 5m russian imagery and have the potential to classify it for a small [sic] fee.

To answer the question of where I am -- Bedford Virginia and I used the USGS data for a quick and dirty but I thought there was some Land cover pre-existing out there for purchase ( High Qual ) maybe I'm mistaken.
