Land is a non-renewable resources for human survival. Land is the form of text, numbers, symbols, maps and other qualitative, quantitative, positioning, timing, visualization fully characterize the attributes of the land. Fully recognize the characteristics of land resources, the establishment of the Land Information System, sustainable and coordinated development of population, resources, environment is of great significance. The development of computer technology, network communication technology, information technology, modern science and technology have greatly contributed to the rapid development and application of the Land Information System. With the wide application of mobile information technology, a combination of mobile information devices and wireless communication network enables the realization of real-time on-site mobile office is no longer a fantasy. Mobile information network technology in land management has a very practical significance and far-reaching impact, there will be a broad space for development. The purpose of this thesis is that through a combination of modern science and technology for mobile geographic information systems, global positioning systems, wireless communication technology, software engineering technology, design and development of the land survey system based on the Mobile Information Device, land survey outside the industry, automated data acquisition, measurement and processing, real-time dynamic update of the Land Information. J2ME and J2EE technology of application of the system to achieve a cross-system, cross-platform operation, support for PDA, mobile phone, most mobile embedded devices. The system has a traditional spatial data display, query, analysis, input and output and other functions, but also the rapid development of GPS technology in the land survey spatial location information collected automatically, positioning and navigation and other functions, but also by GPRS, WLAN, Bluetooth and other ways to achieve the uploading and downloading of data with the server, real-time processing of spatial data and updates. The paper from the land survey of the existing domestic routes, mobile GIS status in the domestic and international development studies of mobile GIS, GPS, software construction technology, wireless Internet and other modern information technology applications in the important practical significance of land management, system technology roadmap and solutions. Next, a brief analysis of applications in the system design the 3S, Mobile GIS, GPRS, J2ME, J2EE, MVC design patterns and other relevant theories and techniques, and provides a theoretical, technical support and protection for the development of the system, and then a detailed analysis of the system design, functional module. System, inadequate, has played a guiding significance for future research practice.
