摘要: 许多嵌入式移动系统能够运用GIS图形在终端设备上显示对象的空间位置.基于GIS的移动系统如果利用比较通用的GIS引擎来开发可以节约时间、降低成本、方便维护.GIS引擎支持不同的地理管辖区域,支持不同类型移动终端,提供必要的工具,支持基于GIS应用的的通用功能.GIS点阵图格元模型、屏幕显示域的定义、屏幕显示域的移动算法及GIS图形自动适应不同类型终端屏幕是实现GIS引擎的重要技术.Abstract: Many GIS based mobile applications display the position of objects in view of the terminal. If we use the GIS-Engine, we can save manpower and time and make maintenance easy. GIS-Engine supports different region and different mobile terminal, it can deal with many applications of different function. The GIS-Engine include array lattice models, definition of display area, matrix movement algorithm, self-adaption to different operating systems, vector objects, and so on.
