GIS数据建库与地图制图一体化方案研究与实现

为了满足地图制图和数据入库的需要,传统的解决方案往往是同时存储两套数据,增加了数据冗余,提高了数据维护成本.以AutoCAD数据入库到ArcGIS Geodatabase数据库为例,提出了数据建库和地图制图一体化的方案.基于数据库设计实现了数据编辑、转换、入库的一体化控制,通过设计要素表达规则和开发地图制图系统,实现了从数据库数据派生制图数据,实现了入库数据和制图数据的一体化管理,达到了一库两用的目的,避免了数据的重复建设.

Study and Realization of Integration Scheme of Database Construction and Map Making In GIS

To meet the demand of mapping and database construction, traditional solutions is to store two sets of data simultaneously, which will increase the data redundancy and improve data maintenance costs. Focusing on AutoCAD to ArcGIS geodatabase, the inte- gration schema of database construction and map making is proposed. Based on database construction, the integration control of data editing, transition and storage is achieved. By designing expression rule and developing map making system, mapping data can be de- rived from database, and then the integrated management of storage data and cartographic data is realized, namely the dual purposes of a library, to avoid data redundancy.
