The California Coastal Records Project, is an amazing website containing more than 12,700 photographs of the California coast from the Oregon to the Mexican border. They have recently added a series of photos of the coast in the 1970's taken by the State Department of Boating and Waterways. They have tools to compare the two series and see what has happened to the coastal areas in the last 30 years. It is very entertaining to browse along the coast looking at places one has been and places where one might want to go.
This site is also interesting from a technology standpoint. The current series of photos were taken from a helicopter using a GPS system linked to a Nikon digital camera, which is linked via Fireware to an Apple Powerbook computer with a big hard drive. Read the propeller-head details here.
