摘要
针对水利水电工程地质数字化图件的特点 ,提出了数字化工程地质图图层分层管理的层次编码方案 ,对属性数据分类进行了补充 ,探讨了属性表结构的编制原则及方案 .
Based on the characteristics of digital engineering geological map in the water conservancy and hydroelectric field, we discuss gradation-coding program of layered management of digital engineering geological map. Furthermore, the classification of the attribute data is supplemented, and the principle and scheme for working out the structure of attribute table are provided.
