About a week ago I managed to find and download the most recent orthoimagery the USGS took of Salem, OR. I've been spending the week setting up GeoServer and massaging the data, and have just recently got it to a working state.

The resolution is on par with what Google has (0.15m) and is even slightly newer (2008 instead of 2005)! Needless to say, it blows the Yahoo imagery of the area out of the water :D

Working with the data has so far been a dream, except for GeoServer's penchant for running out of memory. I'm going to be playing with it for another few days and hope to provide the WMS address to a few other mappers in the area once I'm satisfied with the stability.
