Professional aerial photographic missions are expensive, but periodic updates can be obtained for considerably less money using a hand-held camera in a small plane.
Environmentally related problems such as strip-mine reclamation can be monitored by periodic photography, both color and false-color infrared, obtained in this manner. Problem areas such as uneven settling of leveled spoils can be identified for further work.
Photography and imagery available from government agencies can also be used to supplement data from a baseline aerial photographic mission. Landsat imagery acquired during periods of snow cover may accent subtle structural features concealed by vegetation.
Examples of such techniques, and supporting data, will be on display at the poster session.
