基于GIS的水电工程可视化辅助设计理论与方法

针对当前水电工程设计领域存在的计算机应用水平还有待于提高，设计过程复杂且不直观等情况，在探讨工程可视化辅助设计(VCAD)基本概念及其理论构成体系的基础上，提出了基于GIS的水电工程可视化辅助设计理论与方法，实现了直观方便的设计建模和设计过程的交互控制，以及设计成果的直观形象表达，从而有助于提高工程设计的效率和质量，也为大型水利水电工程设计提供了一种新的辅助手段．

Study on the Methodology of GIS-based Visual Computeraided Design in Hydroelectric Engineering

The authors developed a method of GIS:based visual computer:aided design in the field of hydroelectric engineering based on the foundational concept and its architecture of visual computer:aided design, aiming at enhancing the level of computer:aided designing, simplifying the complex design process and improving the design efficiency. By using the method, convenient design and interactive control could be realized conveniently and the design result could be visually presented. The efficiency and quality of the design could be largely improved.
