烟台市1∶500地形数据整合方法初探

Primary Study on Conformity of Terrain Data with the Scale of 1∶500 in Yantai City

摘要:

为从源头彻底摆脱传统测绘生产过程中图属分离、图库分离的弊端，该文以烟台市1∶500地形数据整合为例，统筹现有地图制图规范与G1S建库需求，在统一制定数据标准的基础上，基于EPS2008软件，提出了一套制图与建库一体化数据整合技术流程，较好地解决了地图与空间数据相互表达的问题，实现了制图与建库的一体化管理。该方法还大大降低了数据重复处理的劳动强度，提高了数据整合转换的准确性和合理性，减少了信息丢失。

Abstract:

In order to get rid of the abuse of separation of attribute form graphic and cartography from database construction, taking topographic data integration in Yantai city with the scale of 1∶500 as an example, standardizing existing specification for drawing maps and GIS database, based on EPS2008 software, a set of data integration process for making maps and database have been put forward. It has solved mutual expression between maps and spatial datas, and realized the integration of mapping and database management, reduced the labor intensity of repeated data processing greatly, improved the accuracy and rationality of data integration and conversion, and reduced the loss of information.
