Low level oblique 1976 and 2007 aerial photos covering the Lake Michigan and Lake Superior shorelines in Wisconsin were used for qualitative mapping of conditions along the shoreline in a GIS database to support comparative analysis between the two time periods. Three components of the shoreline were captured for each time period: (1) beach/nearshore zone; (2) backshore zone; and (3) structure type (points), for non-linear or perpendicular structures (e.g. groins, jetties). This presentation will highlight some of the changes that did take place on the shoreline between 1976 and 2007. We will also present the processes and issues associated with capturing shoreline features using oblique photos within a GIS environment as well as issues related to storing, viewing and distributing these datasets. Finally, we will describe the applications and tools that are being developed to make the datasets and related information available to the public through a web-based mapping portal and its planned integration into the Wisconsin Coastal Atlas.
