Does anyone know of an online source for maps of industrial areas?
The USGS maps on Terraserver or other similar services. They also have aerial photos which can be more useful than the maps.
Thanks for the help!
Maptech has historical USGS quadrangle maps at:

which may be appropriate depending upon the era you model.
