Shoreline residents have identified shoreline and bluff erosion as a critical problem along some parts of the Great Lakes. The rate of shore erosion is affected by the kind of land and rock materials, shoreline shape, current patterns, storm directions, and the use of shore protection structures.

     In this study, ArcView is used to compare the shoreline shape in five aerial photographs of Painesville (Ohio) Township Park from 1954-1999. The objectives are to

1. Recognize shoreline features on aerial photographs.
2. Visualize changes in a shoreline over time.
3. Observe the effects of shoreline devices on rates of erosion.
