.Because the range does not provide significan elevation variation, an additional site will be needed for a DEM ex-periment. An experiment of DSL is to be carried out for the shoreline segment of Lake Erie. Shorelines derived from periodic satellite imaging observations will be used for monitoring shoreline changes from erosion.Causes and impact of shoreline erosion can be analyzed by integration of the shoreline changes and other scientific and social economic data in a GIS environment (Li and Cho, 1996).
