摘要
柱状图表现的内容是和空间位置相关的,基于GIS建立柱状图系统能清晰地表述地层间的空间位置关系.根据柱状图内容与图件表现形式,对地质实体按照空间数据点、线、面格式进行描述,采用面向对象的方法实现了对柱状图的数据组织;系统基于MAPGIS实现,根据数据属性与操作的不同,建立不同的图道来表现数据;对图件的界面操作进行了改善,并提供模板制图功能,实现了对地层单元的综合特征描述.
The content of the column system is related to spatial positions. This paper presents a column system built on a GIS base to clearly show spatial relationships between the strata. According to the content and the representation of the graph, the column describes the geological entities by means of spatial data format, such as dots, lines and areas. The data organization of the system is accomplished by object-oriented methods. System functions are realized based on MAPGIS. System builds different traces to present the data, which has different attributes and operations. It has a friendly interface and provides templates to build the column. The system accomplishes a column by multiple descriptions of the strata.
