Designed for a comprehensive coverage of GIS topics, this book is in three parts. Part 1 covers the fundamentals of GIS including co-ordinate systems, data models, data input, data display and data management. Part 2 includes data exploration, analysis using vector and raster data, and terrain analysis. Part 3 covers spatial interpolation, GIS modelling, regions, and network and dynamic segmentation. Also included are new developments such as the object-oriented model and research-oriented questions, like the effect of spatial scale. Concepts from fields such as geography, cartography, spatial analysis and database management explain the purpose and objectives of GIS operations and the interrelationship between them. Each chapter is divided into two main sections, the first one covering topics and concepts, and the second dealing with applications, usually with three to five problem-solving tasks. To include data sets and instructions for the practice sections, we chose GIS packages as examples for this book, and ArcView software is included.
