摘要
地图数据库作为管理地理信息的一个专业系统,可以将地图信息的采集、存贮、检索、分析处理与图形输出等系统化,以便通过多功能的查询检索为不同的应用部门提供所需信息,通过多要素的综合分析为管理机构提供可靠的决策方案。本文研究了地图数据库的简单实现,在未借用任何第三方开发平台的情况下,实现了目标索引、分类索引和栅格索引的建立,实现了屏幕点击标示目标、开窗标示目标、分类码检索等基本功能,对研制自主知识产权G IS应用系统具有一定的意义。
Cartographic database act as a professional information system of geography information management.It can make the process of mapping data gathering,storing,searching,analysising and map output systemmatically,provide information various department needed by multiple query and searching method,and provide reliable decision-making procept for govermor by analysis method.This paper introduces the realization of a simple cartographic database.The author completed the research independently without using any other third-party software,and the testing system accomplished target index,label index and grid index,finished some pivotal technology such as pickup by point on screen,pickup by windows on screen,query by sort code,ect.This paper also provide some experience for independent intellectual property rights GIS application.
