Photogrammetry

Abstract

The use of photogrammetric techniques in coastal studies has progressed in concert with technological advances over the past several decades. Early studies of coastal change used simple point measurements at control point locations on individual photographs. This was a time-consuming process and did not yield a great amount of information relative to the effort involved. In most cases, a simple rate of shoreline change at discrete locations was produced. Modern applications of photogrammetry, although computerized and somewhat automated, are similarly time-consuming. The data produced from this process, however, enables the delineation and measurement of a variety of parameters, such as morphology, position and volume changes in coastal environments that are of use to a wide audience including coastal managers and scientists.
