Quick Shoreline Coverages from Landsat TM Scenes
Harry BerquistThe shoreline, whether on the coast or in a tributary, is in a constant, sometimes dramatic state of change. Coastal zone scientists and managers, many of whom are now heavy users of GIS, are constantly in need of up-to-date shoreline coverages to answer the questions how much, where, what is the rate of change, and how does it relate to the many other layers of data. This paper will show one method, using remote sensing and image processing techniques, to generate hundreds to thousands of miles of shoreline vector coverage in a very short time from the readily available Landsat TM scenes. It will also look at the accuracy and usefulness of the results and end with a thought about the coming generation of high-resolution satellite images.
