基于MapX的水库地理信息系统研究

THE RESEARCH OF RESERVOIR GEOGRAPHIC INFORMATION SYSTEM BASED ON MAPX

随着空间技术的发展,地理信息系统逐步应用于生活的各个领域.以莱芜市雪野水库地图为模板,介绍使用MapX可视化地实现对水库属性数据库和空间数据库的双向查询技术,以获得较为精确的基本设施信息.同时,介绍了系统基本模块的具体实现方法,包括:地图的基本操作(如放大、缩小、漫游等)、地图的双向查询、地图图层的编辑和鹰眼功能模块.该系统有效实现了水库管理的信息化,实现了水库管理效益的价值最大化.

Along with the spatial technology development,the geographic information system gradually moves into each application field.We take the LaiWu city XueYe reservoir map as the template,introducing to everybody how to achieve visualization of the reservoir bidirectional query of both the spatial database and the property database,obtaining more precise information on basic infrastructure by MapX.Meanwhile,we also introduce concrete realization method of the system basic module,including the map elementary operations（for example,enlargement,reduces,roams and so on）,the map bidirectional inquiry,the map chart level edition and the eagle-eyed function module.This system effectively makes the reservoir information and management benefit to realize the value maximization.
