DLG数据转换为地理国情普查要素数据的技术研究

Research on the Conversion of DLG Data to Data Factors of Important Geographical Conditions

基础地理信息数据是地理国情普查的重要数据源之一,如何充分利用好基础地理信息数据,这关系到地理国情普查数据的生产效率。以1∶10000DLG数据和重要地理国情要素数据为研究对象,通过分析两类数据之间的关系,建立了两类数据的要素对照表,并研究了DLG数据到重要地理国情要素数据的转换模式,最后基于Geoway软件平台,成功将DLG数据转换成重要地理国情普查要素数据。

Fundamental geographic information data is one of the important data source of Geographical Conditions Census,how to make good use of fundamental geographic information data is very important,what is related to the data production efficiency.In this paper,the 1∶10000DLG data is taken as the research object,and the corresponding relation between two classes of data elements is established based on data analysis.This Paper research the conversion mode of DLG data to data factors of important geographical conditions,and success to conversion DLG data to data factors of important geographical conditions based on Geoway software platform.
