This book is based on the premise that research necessary to advance the utility of geographic informatior. systems must extend far beyond concerns with technical issues. The search for formalisms and generalizable principles relative to the behavior and needs of individuals, organizations and institutions is just as important in enabling optimal use of geographic information innovations. This book consists of papers prepared by participants in the NATO Advanced Research Workshop (ARW) on "Modeling the Diffusion and Use of Geographic Information Technologies. " The workshop was held AprilS-II, 1992, in Sounion, Greece. The idea for the workshop and this volume arose from discussions among U. S. and European researchers who had been involved in carrying out studies on the use and diffusion of geographic information innovations and actively involved in critically analyzing each other's work. We felt the time was ripe for reporting studies recently accomplished by the National Center for Geographic Information and Analysis (U. S. A. ), the Economic and Social Research Council (U. K. ), and others relative to these research topics. A workshop would allow contact among and international comparisons with those who were working independently on similar problems with similar or alternative approaches. It would also allow the bringing together of scholars in technology diffusion, management information systems, and sociology with scholars from the GIS community.

This third book in the GISDATA series focuses on the widespread use of geographical information systems GIS in European local government. The editors include a wide range of applications carried out by different professional groups, and offer the opportunity of studying the extent to which diffusion of innovations like GIS are sensitive to national issues such as cultural context, institutional setup and the availability of data.; The book answers key questions such as: what can be learnt from research on organizational behaviour in relation to technological innovation?; what are the classical features of the GIS diffusion process?; to what extent is the adoption and utilization of GIS facilitated - or impeded - by the organizational culture within which it takes place?; and what mechanisms can be applied to enhance the diffusion of GIS? The book covers aspects of diffusion in the following European countries: UK, France, Italy, Poland, Denmark, The Netherlands, Germany, Greece and Portugal.

What is the rate of GIS diffusion? To what extent has the use of GIS really spread? What are the technical and organizational characteristics of the implementation process? What are GIS actually used for? How successfully are GIS implemented? In placing these questions at the heart of their book, the authors set out to stimulate and contribute to the great debate: despite the enormous growth in the acquistion of GIS technology by business and government, little is known about the impact this leading-edge technology is having. Using case studies in a local government context, this book explores the performance of GIS in practice on the premise that any technology-led innovation will only "work" if the proper organizational and management support, infrastructure and culture exist.

In recent years the development of spatial referencing techniques in com puter-based information systems has enormously increased the opportuni ties that exist for the treatment and presentation of both point and interaction data. The extent of this increase has drawn attention to the need for special aggregation and clustering procedures to be developed which enable data to be grouped in an efficient way for analytical pur poses with a minimum loss of detail. In the case of interaction data, economy of representation is particularly important as the analysis is further complicated by the two-way directionality that is inherent in each data set. Procedural rules of this kind are needed not only for descriptive analy sis and spatial accounting but also for hypothesis testing and the develop ment of operational models of spatial interaction. Yet the importance of spatial representation in this kind of research has only recently been fully understood. The first generation of urban development models that were developed in Europe and North America during the 1960's often treated matters of zoning system specification very casually, even though in some cases this imposed severe limits on the interpretation of their findings and it was not until the Centre for Environmental Studies/Cheshire project (Barras et al., 1971) that a serious attempt was made to put forward general principles which could be used as guidelines in future work."
