spatial resolution of 30 meters and the spectral characteristic of the
Thematic Mapper onboard of Landsat 5 or the Enhanced Thematic Mapper onboard
Landsat 7 give a very good basic for the classification of the intertidal
Different methods are used - partly in mutual completion -
in order to retrieve a sediment classification. Mainly the linear spectral
unmixing in combination with unsupervised and supervised classification
algorithms is used.
As results of the data processing, maps of the sediment type
and an assessment of the vegetation coverage are produced. These maps
can be integrated into geographical information systems which provide
the tools for calculating the area of the different surface types and
detecting changes between different acquisition dates.
