The Design And Implementation Of Personal Navigation System Based On Personal Digital Assistant

The various development of computer science promate geographic information system to be endless vitality.With the development of microelectronic technology and photonics technology, the computer has access in the mobile era.As palm-top computers to be represent the increasing popularity of mobile resource management system, using in mobile computers will combinate seamlessly with the main network of the huge number of space is no longer a fantasy.The purpose of this thesis is to use the study is the rapid rise of mobile computing technology,combine mobile maps, the Embedded Geographic Information System applications products,Based on the research and development of the personal digital assistant and other spatial information visualization products embedded applications.In addition to the traditional system of spatial information, inquiries and analysis functions, but more importantly,It is one mobile system, so that users can enjoy any time location-based services.According to the information users need to be arbitrarily cut the other hand,and satisfy the needs of different areas of application needs.In this paper, the field of computer science research involving mobile computing, embedded development (mainly software development).Computer graphics and video, wireless Internet technology and geographic information system mapping study of theory and data organization,Digital Map visualization, GPS positioning and navigation, integrated 3S technology.Firstly, this paper analyzes Embedded Geographic Information Systems Research, a technical background, features and applicationMobile Navigation System for the development and management of resources to provide the technical basis;Second, a PDA-based navigation and Mobile Resource Management System logical framework design.The principle and mode of application specific functions, focusing on embedded platform environment of multi-scale digital map data modelPhysical and logical structure; Finally, the embedded development considerations.gives examples of development --"Yantai Telecom Mobile Navigation resource management system" for analysis and techniques.
