摘要
新型基础测绘已经在全国掀起了新的建设浪潮,基础地理实体是新型基础测绘产品体系的核心,如何高效生产地理实体是摆在测绘工作者面前的重要课题.以1∶10 000 DLG数据为例,通过制作映射表和转换方案,利用程序将存量数据自动转换为地理实体结构,再进行图形和属性编辑、空间身份编码赋值、实体关系构建等,即可实现基础地理实体的改造.实践证明:这是一种快速有效的生产地理实体办法.
Abstract
The new fundamental surveying and mapping has sparked a new wave of construction nationwide.The fundamental geographic entities are the core of new fundamental surveying and mapping product system.So how to efficiently produce geographic entities is an important issue suspending in front of surveying and mapping workers.Taking 1∶10 000 DLG data as an example,by creating a comparison table and conversion scheme,using a program,the existing data can be automatically converted into a geographic entity structure.Then the geometric editing,attribute editing,spatial identification coding,entity relationship construction,etc.can be carried out to achieve the transformation of fundamental geographic entities.The practice shows that it is a fast and effective method for producing geographic entities.
