摘    要:数字填图系统(RGMAP)利用PRB数据流"栈"与不同阶段数据模型的关系,创建PRB数据流"栈"与不同阶段数据模型继承和传递的技术,实现了地质图空间数据库建立的技术流程。1∶5万地质图空间数据库建立流程可分为:地质字典库→1∶2.5万野外手图库(单条路线)→1∶2.5万图幅PRB库(路线总图)→1∶2.5万实际材料图库→1∶2.5万投影到1∶5万图库→1∶5万地质图空间数据库→元数据库七个阶段。本文按建库流程,分析各阶段可能产生的质量问题,探讨不同阶段质量控制要点及相应操作技巧,从而提高数据库建立的质量与效率。

关 键 词:数字填图系统  空间数据库  质量控制  操作技巧

Abstract:The technical process for building spatial database of geological map is achieved by the succession and transfer technology in Digital Mapping System(RGMAP) which is based on the relationship between the PRB(point-routing-boundary) data stream stack and different-stage data model.The process for building spatial database of 1∶50000 Geological map can be subdivided into seven steps: geology dictionary database,1∶25000 field material database(single route),1∶25000 PRB database(total routes),1∶25000 factual material database,1∶25000 database projects onto 1∶50000 database,1∶50000 geological map spatial database and meta-database.We analyze the possible mistakes in every stage of the building process,discusses the key point for the quality control in each stage and related operation skills to improve the quality and efficiency of spatial database building of 1∶50000 geological map.
Keywords:Digital Mapping System  Spatial database  Quality control  Operation skills
