基于UML的工程地质等值线图模型

针对等值线制图的主要问题，采用UML(统一建模语言)建立可视化信息模型，反映了基于GIS 的等值线图的主要组成及关键制图过程，指导了基于GIS 的制图系统开发；采用ArcEngine9.1软件和C#.NET 开发环境解决了工程地质中各种类型的等值线动态生成和复杂标注等制图表现问题，实现了原始数据管理、空间插值计算和制图表现等的集成应用。

Abstract: In order to solve problems of isograms production, visual information models of engineer geological isograms is created by Unified Modeling Language. The models can reveal the parts and internal relationship, and analyze critical process of isograms production, which contribute to development of mapping system based on GIS platform. Guided by the models, a mapping system of engineering geological isograms is designed and realized on C#.NET and ArcEngine9.1. The system can produce dynamically kinds of isograms and complicated mapping elements, and realize integration application of source data management, spatial interpolation and mapping representation.
