Fig. 22.3 Procedure of stepwise integration of a simple model on land use to identify areas
sensitive to high rainfall: (a) joining land use and rain gauge, (b) interpolation of precipitation,
(c) classification of high rainfall, (d) generalization of sensitive areas (see text for more details)
use, and are sensitive to high rainfall. Using different socio-economic scenarios, the
land-use model thus calculates the suitability for a specific agricultural land use.
Data from a projection of precipitation are aggregated to zones of high rainfall. All
information is combined to identify sensitive areas.
The first step of any model integration is to make all data and model-interfaces
available within the technical framework and to the software (by file managing
systems etc.). Fortunately, common operation systems do not bother the user with
data connectivity problems anymore. Standard file formats should be accessible to
the GIS directly, as long as they are geo-referenced.
Basic methodical requirements of model
integration are multifaceted (see
