The Sarasota Bay study area is highly urbanized. Since the early 1900s, dredge and fill activities and various shoreline hardening projects have resulted in significant losses of ecologically important habitats. This information was gathered as part of a study to assess restoration opportunities in the Sarasota Bay National Estuary Program (SBNEP) watershed.
Shore type feature protocols were developed for mapping and GIS database development according to a bay segmentation scheme previously adopted by the SBNEP for its technical projects. A detailed photointerpretation key was assembled to guide the work process of mapping and GIS database development. Dates of aerial photography encompassed 1998, 1999 and 2001.
Imagery was derived from source photography at scales between 1:8,000 and 1:24,000 as obtained from the Southwest Florida Water Management District (SWFWMD), Manatee and Sarasota County Governments. Shore type features were mapped via photointerpretation and groundtruthing according to a cover classification system including geomorphic, shore morphology and intertidal vegetation tiers. Query analyses were performed to tabulate and chart the proportion of feature classes within the entire study area and within each bay segment.
