| 摘 要： | 组件式GIS已成为地理信息系统发展的一个重要阶段.ESRI公司推出的组件式GIS--MapObjects小巧灵活,运行速度快,开发方便,用很少的代码即可实现最基本的GIS功能,因而得到广泛应用.但MapObjects缺少直接符号化的函数,给用户实际制图工作造成不便.本文采用VC开发工具,结合COM技术,通过设计符号化的组件对这一问题加以解决. |
| 关 键 词： | GIS 组件式GIS MapObjects 组件 |

| Abstract: | Component GIS (ComGIS), a new technology based on COM(Component Object Model),is currently a main means in GIS technology. Recently, this technology has developed so fast that more and more ComGIS softwares are available in the market. This paper gives a detailed review of ESRI's MapObjects. MapObjects is flexible and open, but can not be symbolized. This paper deals with the technique for symbolization by using Visual C++ and the ComGIS software. It is believed that ComGIS will grow into an important branch of Earth System Science. MapObjects is surely to be used widely, and can play an important role in Geographic Information Systems. This study helps to understand the development of core GIS's function by using VC combined with ComGIS. |
