Design And Implementation Of Agricultural Information Acquisition System Based On GIS

With the embedded technology and wireless communication technology widely used. Geographic information system for mobile mobile intelligent terminal (Mobile GIS) geographic information system has become a hot research. Mobile GIS is a set of navigation, positioning, maps, because it is widely used in various areas of software solutions for integrated query and spatial data management. Mobile GIS is a mobile intelligent terminal as the carrier, combined with spatial information technology, embedded technology, mobile database technology, wireless communication technology (GSM/CDMA) and satellite navigation (GPS) technology, integrated system, it is the geographic information systems and with new models application development.Meaning from the background papers, elaborated Mobile GIS Research. Mobile GIS, spatial information technology, embedded technology, mobile computing and wireless communications technology, and combine these techniques are based on Mobile GIS field information collection system research and design. Course of the study were as follows:First, in theory, mobile GIS system and its key technologies are discussed. Mobile GIS research,3S technology, embedded technology and wireless communication technology. Mobile GIS-based agricultural information collection system developed to provide a theoretical basis and technical support.Secondly, the system needs analysis, based on the proposed system design principle of the system usage, according to the system’s overall structure and logical structure, raised the overall framework of the system and basic operation; From a geographic information system, spatial orientation, data acquisition, wireless data transmission, database operations and function modules design, etc., from the selected database platform, system design, database access interface:Key arrival and system development class model designs.Finally, in systems analysis and design, based on the combination of mobile GIS development. NET Compact Framework development platform for Windows Mobile phone operating system to realize agricultural information collection system and mobile GIS data collection feature. Gives a development environment configuration, and describes some of the details of such a development.
