摘要
PRB数字地质填图前期数据准备包括软硬件准备、地形图数值化、前人资料的收集和室内录入、多元数据的叠加和整合、PRB过程字典库的编制等方面 .PRB过程字典库由结构化字典、填缺式字典和描述性字典 3部分组成 .结构化字典和填缺式字典可直接查询 ,为 1~1.5级字典 ,描述性字典为 2级字典 ,需要 2级查询 .不同的字典类型均以文本文档的形式存在 ,文件名后缀为 .DIC .
Prophase data preparation for PRB digital geological mapping includes preparing softwave and hardware, numerical value of relief map, former data collecting and indoor documentation, superimposing and merging of multi-element data and the PRB dictionary editing. PRB dictionary consists of structural dictionary, filling dictionary and describing dictionary. The first two dictionaries are 1 to 1.5 level that can be directly referred to, while the other one is the 2 level dictionary which should be referred twice. The documents of different dictionaries are all text documents and the suffix of documents is DIC.
