Yesterday, students in the Aerial Photo Interpretation class (FORT 230) visited selected sites on the aerial photos they are studying. Using the principles of interpretation: shape, shadow, pattern, association, texture, tone/color, and relative size, they compared the scene on the photo with what is actually on the ground today.
Given that the sets of photos we are using were taken in 1977, the element of time must also be included in the interpretation. Some areas have been harvested and others have grow in from previous harvests. Little of the area has changed through human use, however.
Here is a Google map of the sites the class visited:

Digital pictures were taken at each stop and then geotagged with the location coordinates. Follow this link to see the geotagged images on a Yahoo Map in Flickr. Picasa albums also offers geotagging on a Google map as shown in this link. Each provider and format has its own advantages. There is probably a universal tool out there to combine these into one view.
