【摘要】 地质剖面图是表达地质信息的重要专题图件,不同于传统G IS水平空间制图,其表现内容繁杂、过程复杂。本文采用G IS模板技术,基于UML(统一建模语言)对剖面图要素进行概念模型和逻辑模型分析。针对地质剖面插值连线或填充制图的难题,采用贝塞尔曲面对剖面进行精确的空间插值。最后基于ArcEngine组件式G IS平台开发了剖面图动态制图系统,实现了地质空间数据库管理与剖面图自动制图的集成应用。更多还原

【Abstract】 Section map is an important thematic map expressing geological information,which is different from the traditional GIS 2-D mapping.The content and production of section map are complicated.The paper uses technology of GIS template and analyzes the elements of section map with concept model and logic model based on UML.According to the problems of section interpolation for drawing line and filling symbols,the paper uses Bézier surface to interpolate spatially for section.Based on these,mapping system of geologic section has been developed on Arc Engine platform and realized the integration of geological spatial database management and section map automatic production.更多还原
