Features: This book consists of 10 chapters, systematically introducing the collection, processing, and handling of fundamental geographic data, as well as the construction of fundamental geographic databases and the principles, techniques, methods, and applications of fundamental geographic information system development. The content includes: basic concepts of fundamental geographic data and fundamental geographic information systems, data characteristics, key technologies, current status, existing problems, and development trends of the system; projections and coordinate systems involved in fundamental geographic information systems, as well as methods for converting between coordinate systems, and the division and numbering of topographic maps; techniques and production methods for collecting fundamental geographic data; an introduction to the C/S and B/S architectures of the system, software and hardware structures, and configurations; database design and related data organization; data format conversion, mathematical foundation transformation, data integration, and data entry; data update strategies, methods, and database update techniques; the standard composition of fundamental geographic data, quality control technologies and methods in data collection and processing; the implementation methods of major functions in fundamental geographic information systems; as well as the technical foundations, mechanisms, strategies, and key technologies for data sharing. Fundamental geographic information systems utilize computer technology, network technology, and 3S technology to construct accurate, dynamic, and efficient shared fundamental geographic databases and their management and application systems, making them the spatial positioning foundation for information systems across various industries and achieving fundamental geographic data sharing. Fundamental geographic information systems provide comprehensive, high-quality, and efficient fundamental geographic data services for regional planning, construction, management, and the general public, offering strong support for regional informatization construction, particularly for integrated applications related to geographic information systems. This book systematically elaborates on the principles, techniques, and methods of collecting, processing, and designing and constructing fundamental geographic data and fundamental geographic information systems. It can serve as a textbook for undergraduate and graduate students in geographic information systems and surveying and mapping, as well as a reference for professionals engaged in surveying production, geographic information system design, development, and application.
