[Abstract]:With the rapid development of embedded system, its application field is more and more extensive. In embedded operating system, Android system is open, stable and versatile. Gradually become the mainstream operating system of embedded equipment. The combination of GIS and embedded system has become the inevitable development trend of GIS. The research of embedded GIS based on Android platform can not only reflect the strong ability of GIS to display and analyze spatial data, but also have small embedded devices and low power consumption. Mobile features, thus making GIS has a wider user community and applications. According to the basic functions and requirements of GIS, this paper designs and implements an embedded GIS based on Android platform. The basic theories and algorithms involved in the system are studied emphatically, and the basic functions of the system software are realized by using the general steps and methods of the software design of the Android system. The operation effect of each function is shown. Firstly, this paper briefly describes the development and application of embedded GIS. On this basis, the hardware selection scheme and integrated software development environment of the system are proposed, and through the system MVC architecture design, system software requirements analysis and system module division. The overall design scheme and module design scheme of the system are put forward, and the technical route for the implementation of the whole system is established. Then, the spatial data management of GIS is studied and analyzed. The structure of spatial data, the design method of map format and the spatial index algorithm are studied. The spatial data storage format and map file organization structure of the system are put forward, which provides the source of spatial data for the next realization of digital map generation and digital map analysis. Finally, this paper describes the design and implementation of the system software in detail. Through the analysis of the Android platform architecture and design process, object-oriented programming as the idea. The user interface design of the system software is realized, and the structure of static class is built. On this basis, the specific methods of function realization in map generation and map analysis are described in detail. Finally, the design and implementation of the whole system software are completed. After testing the effect and performance of the function realization, the embedded GIS based on the Android platform can run stably, which basically realizes the initial goal of the design. It meets the basic needs and requirements of GIS and has good applicability and stability. It can be used for reference in the design and implementation of other similar systems.
