摘要
本文从近20年地质调查填图工作中计算机野外数据采集技术研究的现状和存在的问题入手,探讨与地质填图比例尺无关的野外路线观测与调查的数字组合模型及其机制,并导出了PRB过程、PRB数据模型、PRB的基本过程组合的规则、公共机制、PRB数据操作、PRB字典、三级PRB体系、PRB数据流“栈”、PRBS数据质量定量评价体系等构成的PRB数字填图技术理论体系。从软件体系、硬件体系论述了PRB数字填图的具体实现方法。
Starting with presenting the present situation and existing problems of the on - site digital data collection in the past 20 years＇ geological mapping, this paper discusses the digital combination model and its mechanism of the field geological investigation unrelated with the mapping scale. Then, this paper further discusses the technical architecture of PRB digital mapping made up of PRB process, PRB data model, combinational rules of PRB process, common mechanism, PRB data operation, PRB dictionary, three - class PRB system, PRB data flow stack and the quantitative evaluation system of PRBS data quality etc. The concrete methods of realizing PRB digital mapping are also discussed from angles of software system and hardware system.
