I talked to someone with their GIS department today and they plan on
releasing their 2010 orthographs in a few days. They also plan on
downsampling the data because each tile is ~1 GB, leading to a total size of
120 GB or so. I'm also talking with them about getting the data from the
edges which are outside their tile system but photographed.
