The Research And Realization Of The Wireless Transmission On Vector Graphics Plotting Based On Embedded GIS

Since the emergence of the geographic information system (GIS), it has been widely used in major companies. Under the combination of geographical information system and the embedded, create a new embedded GIS industry. When application of embedded GIS, need to use the GPS navigation, so you can pinpoint your current location. Data acquisition is an import work in scientific research, especial in the field of natural science where the field data is often involved. Based on the Android platform, and combing advanced technologies of mobile GIS with LBS, a field data acquisition system of scientific research was developed which can be applied widely. The purpose of this paper was to improve the traditional data acquisition methods and increase the efficiency of field data acquisition by using the mobile GIS technology combination with intelligent electronic devices.Plotting wireless transmission system is mainly used in the field work, such as forestry, implements the vector graphics plot, plot, plot to receive, record query four modules. The vector graphics plotting include maps show, positioning, selection of vector graphics, vector graphics attribute editor, map the position of the display to the user as the center of the electronic map information, on the basis of these features vector graphics plotting; Plotting to send function mainly includes plotting data acquisition, plotting data description, the user after completion of vector graphics plotting to information extraction from the plot, to describe, and then send the plot information; Plotting receiver function mainly undertake choosing according to user’s name and date received; Can record query functionality based on user name and plot data description query already plotting data sending or receiving information.Paper based on the Android platform, using the embedded GIS in the field of location based service (LBS) in cutting-edge technologies, implement used in forestry and other field plot of wireless transmission system. System uses C/S architecture, the client for data storage, using SQLite server using MySQL for the record and plot properties of storage. Mechanism using HTTP requests for wireless using JSON lightweight network transmission format of plotting information encapsulation, sent to the server.
