CoastGIS'99: geomatics and coastal environment
Concluding remarks
The use of GIS for the valuation study turned out to be very time
consuming. Almost 90% of the total project time were used to compile
and process the raw data into a homogeneous database. However, when
this database was established, the powerful analysis functionalities of
GIS allowed for an accurate, high resolution calculation of total protected
values per flood unit and height interval. With this, it is possible to
determine optimal technical solutions (in a cost-benefit manner) as
well as to establish priority lists for coastal defence works. Furthermore, with the cd-GIS it will become possible to simulate the consequences of different climate and land-use scenarios for coastal defence
planning. Potential conflicts between user functions (for instance coastal
defence, tourism or nature conservation) and the natural system can be
identified by means of impact matrices and overlays (Van der Weide,
1993). In conclusion, GIS is a powerful tool for integrated coastal
defence management.
