PRODUCT – Air Photos
Airphotos are the traditional object of a photogeology study. Usually, they are exposed in color infrared (see Airphotos link). There is complete coverage of the US. They are used for photogeology but are limited in timeliness because they are, on average, six or eight years old. However, this can work to your advantage because they are useful in documenting conditions (see Expert Witness) and, because the historical archive can span some 70 years you might find old well locations.
