【摘要】 Linux正在嵌入式系统中得到越来越多的使用,基于嵌入式Linux的应用也不断 被推出。嵌入式地理信息系统(GIS)是其中很重要的一个方向。首先讨论了嵌入式GIS技术的架 构、发展动态及相关技术背景。然后,在搭建相应的开发环境的基础上,给出了基于PXA250硬件 平台和嵌入式Linux的嵌入式GIS软件的整体架构。最后探讨了在嵌入式GIS开发中的一些相关 技术。更多还原

【Abstract】 Linux has been used more and more in embedded system. The application based on embedded Linux has been promoted among which the embedded GIS becomes an important direction. The architecture , development and technological background of Embedded GIS are discussed and the developing environment is constructed. Then, the architecture of embedded GIS based on PXA250 and embedded Linux is presented. Finally, relative technology in the development of embedded GIS is proposed.更多还原
