Remote sensing techniques in estuaries and coastal zones - an update

This paper reviews briefly the current state of the use of remote sensing i n estuaries and coastal waters. This covers the established uses, the recen t developments in relation to hyperspectral imaging systems (imaging spectr ometers), interferometric SAR and lidar bathymetry. The opportunities that are expected to occur soon, as 1-m resolution space-flown systems become av ailable, are also discussed.
