面向野外地质填图的空间实体对象表达
OBJECT STYLES OF SPATIAL ENTITY FOR FIELD GEOLOGICAL MAPPING BASED ON OBJECT-ORIENTED METHOD
【摘要】 开展以计算机技术为核心的辅助地质填图野外数据采集 ,必须以野外地质空间实体数据的采集为主线研制地质填图野外数据采集系统 .运用软件工程学和系统工程学的方法 ,把面向对象软件工程开发技术与实际野外地质填图流程相结合运用到系统开发的各个环节 ,研究面向野外地质填图空间实体的分析方法和面向野外空间实体的数据对象的分析模型 ;建立了野外地质空间实体E -C -R模型、类层次结构及信息结构模型 ,为系统实现及系统集成提供了可行的技术开发路线 .
【Abstract】 In order to carry out field geological mapping and data acquiring with computer assisted technology, the focus should be put on the acquiring of field geological spatial entity data, so as to develop geological mapping field data acquiring system. With the help of software engineering and system engineering, the combination of object-oriented software developing technology with practical field mapping is applied in every stage of the system development. Methods for the analysis of the field mapping spatial entity and the analysis models for its data object are studied. In this paper, the building of E-C-R model of field geological spatial entity, class hierarchy and information structure model are discussed. These models have been the base of this system development and satisfactory effect has been achieved .
【Key words】 field geological mapping; geological spatial entity; object-oriented technology; E-C-R model; information structure model.;
