摘要
介绍了单纯二次开发、跨平台集成开发和组件式GIS开发等三种应用型GIS开发方法;说明了河道信息系统的数据组织和主要功能;并以基于MapX自行开发的河道信息系统(RAIS2.0)为例,具体讲述了MapX的数据组织和图形变换、图形编辑、数据查询、数据绑定等操作机制.结果表明,组件式GIS开发方法集中了可视化软件开发工具与地理信息系统工具软件的优点,为快速定制独特的应用型GIS提供了便捷的手段,将在河道信息管理中有更加广泛的应用前景.
The advantages and disadvantages of simplicity secondary development, integrated cross-platform development and component GIS development are descirbed. Secondly, the data organization and principal functions of the river information system are expounded. And then, taking the river information system, which was developed by the authors, for example, the data organization based on MapX, the operational mechanism of map counterchanging, map editing , data querying and data binding are described in detail. The conclusion shows that the development method of component GIS has combined to the merits of visual software development tool and GIS tool software; and it supplies convenient and quick means to celerity custom-tailor unique application type GIS; and it will has the more comprehensive potential application to river across information management.
