摘要
嵌入式GIS技术在PDA、手机等移动设备中的应用快速增长,为解决在嵌入式环境中如何快速处理GIS栅格数据,实现地图和影像的快速浏览、局部放大缩小等问题,以Windows CE或Windows Mobile系统为例,给出了一种基于嵌入式GIS技术实现对海量栅格数据的快速处理、浏览显示等互操作的关键技术,并详细阐述其程序设计和实现方法。
With rapid development of the current PDA, mobile phones and other mobile devices embedded GIS expanded quickly. To deal with massive grid data in embedded format, the processing of viewing maps and images, partly zooming out or zooming in etc. should be effective and quickly.Based on Windows CE and Windows Mobile system, rapid processing massive grid data techniques for viewing and displaying operation are discussed. Finally the real program design and code-level system realization are presented in detail.
