Coastal zone management and environment assessment
covers the collection of topographic elevations and hydrographic
depths to monitor and determine the position and condition of coastal
resources and habitat, including vegetation, sea birds and fisheries.
Survey data typically extend several hundred meters (and sometimes
as much as a kilometer) inland from the water line to several thousand
meters offshore. Project lengths range from a few kilometers to
thousands of kilometers along the shoreline. Such surveys are typically
combined with other data sources, such as multibeam bathymetry,
seabed imaging, multispectral or hyperspectral imaging and aerial
photography. In these cases, integrated data sets are provided to
resource managers who are responsible for these coastal zones. They
are often not interested in elevations alone, but in elevations
in the context of other ancillary data.
