Terraserver uses USGS data for it's aerial photos and topographic maps.

It's old because the government isn't updating the data.

Since land masses don't change that much, I've found the topo and aerial 
data to be of great value in my own off-road explorations out west. You 
do need to be aware of the dates on the data you're looking at though.

Newer aerial photos are available for a price. Newer topos aren't.

What I don't like is the Terraserver tile number limitation on the 
Terraserver web display. There are better USGS/Terraserver display 
utilities that can display high-res tiles across a 1600x1200 screen 
resolution or higher. This makes looking at the data much easier, as you 
get to see more. Additionally, using these utilities you can import and 
export GPS tracks and waypoints, so you can see where you were, or 
create tracks to follow when you go out exploring right there on the 
map, aerial photo, or aerial photo with map overlaid on top.
