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。
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 exist-ing data standards in Shandong province,by studying the automatic processing methods of encoding con-version and data structure restructuring,data automatic model transformation process based on the charac-teristics 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.
