Features: This book is a summary of the author's many years of experience in teaching and scientific research. It discusses the concepts of geospatial information science, the fundamental theories of spatial information systems, and the structure and functions of spatial information systems. The book covers map data acquisition, remote sensing data acquisition, GPS data acquisition, and 3S technology integration. It also analyzes geographic spatial cognitive models and geographic data models, object-oriented geographic data models, and spatiotemporal data models. Additionally, it explores digital elevation models and their data structures, the establishment of triangular irregular networks (TIN), and the creation of regular grid digital elevation models (DEM). The book also addresses algebraic transformations of spatial graphics, spatial relationships, and spatial analysis. Furthermore, it covers the multi-scale characteristics and automatic generalization of spatial data, spatial data visualization, and the core technologies of modern spatial information systems, as well as new developments in spatial information systems.
