摘要
科普资源发布系统利用GIS强大的空间查询与分析功能,方便市民浏览、查询与统计科普资源情况,掌握更多科普知识。本文主要论述了系统设计与实现过程中应用的关键技术,详细给出了栅格影像自动选择的方法,矢量栅格匹配的原理,以及统计图的绘制技术。最后介绍了系统的开发模式与软件环境,给出了统计效果图。
The popular science resources publishing system takes use of the powerful functions of GIS on spatial research and analysis to make the citizens convenient in browsing and searching the distributing of popular science resources and to learn more knowledge.This paper mainly discussed the key technology in the process of the system design and realizing.It gave out the method and strongpoint of grids automatic selection,the principle and advantage how to match the vector and the grid layers and the technology how to protract the statistical maps.Finally,it introduced the development mode and software environment of the system,and gave out some statistic sketches.
