ABSTRACT
The difficulties presented by unstructured decision situations, the need for computer support systems, and the concept of spatial decision support systems were discussed in Chapter 1. In Chapter 2, the progression of SDSS was presented in order to give an historical perspective and also to provide an idea of where the techniques and technology are heading in the future. Spatial decision support systems are characterized by a wide variety of approaches, application domains, development techniques, technologies used, and the complexity of the software configurations. However, to be considered spatial decision support systems (SDSS), they must contain certain components. These common components as well as how they are specifically included in SDSS and how interaction among the components is facilitated will be discussed in this and the next chapter.
