摘要
空间数据库在流域空间信息系统中占有十分重要的地位,是进行信息化流域管理的数据基础。以滇池流域为例,利用地理信息系统技术和计算机技术,采用一些公开免费的数据资源和软件平台,经过资料搜集、数据库建模、数据处理和数据录入,在很短时间内,迅速完成了滇池流域空间数据库的建立。该空间数据库具有成本低、实现快、更新简单等优点,能实现滇池流域地理空间数据的快速查询和结果展示、渲染,可满足市级环境管理工作的日常需求。
Geospatial database plays an important role in Watershed Spatial Information System,which is the data base of informational watershed Management.Taking the Dianchi Lake Basin as an example,in very short time,this author quickly finished building Dianchi Lake Basin geospatial database by using geographic information system technology,computer technology,and free public data resources and software platform,through data collection,database modeling,data processing and data entry.This geospatial database with merits of low cost,fast implementation and updating simply can achieve the Dianchi Lake Basin fast query of geospatial data,results display and romance;can meet the daily needs of daily municipal environmental management too.
