DLG数据模型自动转换程序设计

Design of DLG Data Model Automatic Conversion

摘要:

基于国家测绘地理信息局试运行的《1∶10000（1∶5000）基础地理信息地形要素数据规范》和山东现有数据标准情况，通过研究编码转换、数据结构重组等的自动处理方法，开发了基于山东省1∶1万数字线划图(DLG)数据特点的自动模型转换处理程序，总结了DLG数据模型自动转换的方法。

Abstract:

Based on "Terrain Factors Data Specification of Geographic Information with the Scale of 1∶10000(1∶5000) " issued by the National Geographic Information Bureau of Surveying and Mapping and the existing data standards in Shandong province, by studying the automatic processing methods of encoding conversion and data structure restructuring, data automatic model transformation process based on the characteristics of DLG in Shandong province with the scale of 1∶10000 has been developed, and the DLG data model automatic conversion method has been summarized.
