Tidewater Shorelines in Broward and Palm Beach Counties,Florida: An Analysis of Characteristics and Changes Interpreted from Color,Color Infrared and Thermal Aerial Imagery.

摘要

In South Florida,pressures to extend and modify tidewater shorelines are very strong. These modifications include canal excavations,dredging and filling, bulkheading,erection of sea walls,and dock construction. Access to tidewater is much coveted and competition for such access is keen. Using color infrared aerial photography flown at 5000ft.,eight types of tidal shorelines are distinguished in a portion of NASA Test Site 164. Comparisons are made with other imagery,including high-altitude (60,000ft.) photography and that from the Reconafax and Bendix Thermal Infrared sensor systems;and the degree to which these shoreline types are observable is noted. Some changes over time are also indicated,in particular the extent of additional modifications during a period of approximately one year. (Author)
