"In recent years we have witnessed an increasing interest in Geographic Information Systems (GIS). Despite the wave of popularity for these systems it is noteworthy that they have been around for almost thirty years. It is the development of universally available computers and new types of software which has made these systems so popular and wide-spread at the present time. Geographic Information Systems have moved from a concern with geo-processing in the 1960s, to management of geographic information in the 1970s and to first steps of spatial decision support systems in the 1980s. Today, geographic information systems incorporate many state-of-the-art principles such as relational database management, powerful graphics algorithms, elementary spatial operations such as calculating the accessibility or nearness of geographical objects to one another, buffering in vector maps, polygon overlay with logical operations, interpolation, zoning and simplified network analysis, as well as a high degree of user-friendliness through windows, icons, menus and pointers interfaces. However, the lack of analytical and modelling functionality is widely recognized as a major deficiency of current systems. There is a wide agreement in both the GIS community and the modelling community that the future success of GIS technology will de-pend to a large extent on incorporating more powerful analytical and modelling capabilities. There is an increasing need to link spatial depictions in a GIS framework to spatial analysis techniques (statistics and modelling). Such a cross-fertilisation will also be of great value for policy analysis and evaluation in space. The various contributions in this volume bring together reflective, technical and applied research work at the interface of GIS, modelling and planning."
