This book constitutes the thoroughly refereed post-proceedings of the International Workshop on Integrated Databases, Digital Images and GIS, ISD'99, held in Portland, Maine, USA in June 1999. The 18 revised full papers presented went through a double reviewing process and were selected from nearly 40 original submissions. The book is divided into parts on object extraction from raster images, geospatial analysis, formalisms and modeling, and data access.
The past 20 years can be regarded as the adolescence of geographic information science (GIS), as it grew from a burgeoning area of study into a mature and thriving field. During those two decades, the International Journal of Geographic Information Science (formerly Systems) (IJGIS) was one of the most prominent academic guiding forces in GIScience
The late Daniel J. Elazar was increasingly concerned with the distortions of democracy in contemporary society. In Commonwealth, he brought together a distinguished group of political scientists to examine the Swiss model of democracy, in its original emphasis on community, or the "commonwealth." Contributors to the volume take the Swiss model as a base from which to critique the liberal model, best exemplified by the United States. While it is admittedly the best contemporary example of liberal democracy, or "civil society," America also displays the problems of this model. The modern idea of communal democracy has almost completely disappeared from the United States, contributors argue. In...
This text shows how the principles and technologies of object-oriented programming, distributed processing and internet protocols can be embraced to further the reliability and interoperability of datasets for the professional GIS market. The book describes the central concept of the interface specification between the data consumer and producer - the Virtual Data Set VDS. It then examines how VDS deals with two other classes of model - field representations and modelling uncertainty. The final part of the book looks at implementation, describing how the VDS interacts with PostScript, Java, and Object-oriented modelling environments.
The study and application of spatial information systems have been developed primarily from the use of computers in the geosciences. These systems have the principle functions of capturing, storing, representing, manipulating, and displaying data in 2-D and 3-D worlds. This book approaches its subject from the perspectives of informatics and geography, presenting methods of conceptual modeling developed in computer science that provide valuable aids for resolving spatial problems. This book is an essential textbook for both students and practitioners. It is indispensable for academic geographers, computer scientists, and the GIS professional. Serves as the first comprehensive textbook on the field of Spatial Information Systems (also known as Geographic Information Systems) Contains extensive illustrations Presents numerous detailed examples
