GIS建库与制图一体化的研究

Research on Integration of GIS Database Construction and Drawing

随着社会经济的迅速发展,城市化进程的不断推进,地图信息数据分析与建库已经成为国土资源信息化的重要环节,但地理制图数据与建库数据在存储和表达上存在很多不一致,在操作过程中可能导致操作重复数据冗余的情况,数据维护和更新也较为困难。为了解决上述问题,本文引入"建库与制图一体化"思想,首先建立GIS数据库,在ArcGIS软件中处理数据,实现从地理数据转化为制图数据,利用数据库的分析功能进行数据处理,最后进行地图整饰完成制图。这种基于数据库的设计实现的数据编辑与更新,将制图与建库工作融合在一起,不但能够提高数据的精度,减少数据冗余,满足数据快速同步的要求,而且提高了数据的生产效率,减少人力物力的投入,有效地保障了制图数据与建库数据的一致性。

With the rapid development of social economy and the continuous advancement of urbanization,map information data analysis and database construction have gradually become an important part of land and resources informationization,but there are many storage and expression of geographic mapping data and database construction data.Inconsistent,it may lead to duplication of data redundancy during operation,and data maintenance and update is also difficult.In order to solve the above problems,this paper introduces the idea of"integration of database construction and drawing".Firstly,it establishes GIS database,transforms it from geographic data into drawing data in ArcGIS software,uses data analysis function of database to process data,and finally performs map decoration.Complete the drawing.This kind of database-based design realizes data editing and updating,which combines drawing and database construction work,not only can improve data precision,reduce data redundancy,meet the requirements of fast data synchronization,and improve data production efficiency.Reduce the input of manpower and material resources,and effectively ensure the consistency of cartographic data and database data.
