positions, to be added. In essence, the system would act rather like a 'Juke Box', where
the user enters a request, and the record, or data layer is retrieved on demand, thus
providing a Layered Information Search and Retrieval System (LISaRS).
Arguably, many systems for retrieving remotely sensed data do already exist
(see for example NOAA's image catalogue on the Internet (Fig. 6)). However, the
human computer interface (HCI) is frequently too complex for the non-specialist user to
understand and use. Moreover, the data supplied is not geared toward a specialist
application, and it is not often arranged in a hierarchical fashion. Such systems are
limited because the potential user still needs to know what data would be necessary for
their application (requiring a certain knowledge about the sensor and its characteristics)
and would also have to know how to get the information out of the data. The LISaRS,
on the other hand, would be specially developed for coastal zone management, and
would provide a simple HCI with the prompts that are needed to deliver the data and
