Detecting seagrass spatial features using Remote sensing

rs_inshortRemotely sensed data and imagery have been widely applied over the years to coastal environments with varying degrees of success, largely dependent upon the application. Aerial photography, in particular, emerges as a major source of information that has considerable appeal for many coastal applications, primarily because of a user-requirement and desire for “high” spatial detail and visual familiarity and because of the relative ease with which the imagery can be used. The low cost of aerial photography for many local-based studies is also an important consideration. Relatively poor spatial resolution of most satellite data and imagery has, until recently, also meant that they have not become as widely used as was initially expected, despite the considerable advantages offered by greater spectral and temporal resolution and area coverage. With time, the spatial resolution of satellite imagery has improved considerably and this has greatly increased its potential for more widespread use.
