Embedded GIS is a kind of newly developing application field. It' s a production of the combination of GIS and newly developing embedded hardware. It is the extension, supplement and development of intrinsic GIS field. The combination of Embedded GIS and PDA to accomplish map real-time display in mobile computing condition will have a good future.The purpose of the study in this article is to develop a geospatial information visualization system based on PDA. The system integrates the mobile computing and mobile map technology and has satisfied the visualization, query and analysis of spatial information. It is more important that the system is in mobile environment and enables users to enjoy Location-based Service anytime and anywhere.The research topic of the article involves computer science, such as mobile computing, embedded GIS developing, computer graphics and wireless networks, and the science of surveying and mapping, such as the principle and data organization methods of geographic information system, the visualization of digital maps, location and navigation based on global positioning system (GPS).At the beginning of the article, it analyzed the research progress, technology background, characteristic and applications of Embedded GIS ;Than it bring forward the complete logical framework design based on mobile Embedded GIS and the principle of function realization; The emphases of the analysis is the data model, logical structure and the physical organization of multi-scale digital map based on PDA platform; It also presents a software example of Embedded GIS developed with Embedded Visual C++ called "eGis" ; At last it summarized the factors of developing Embedded GIS and prospects the future with development instance.
