基于MO技术的流域水文水情信息系统

Development of valley hydrology GIS based on MapObjects technology

清江流域水文水情专题GIS采用了VC ++及组件GIS技术 ,界面友好、操作便捷 ,实现了水文水情警示、暴雨警示、暴雨评估分析等功能 .在系统的数据库设计中 ,采用了异构数据模型 ,这种数据的组织方式 ,很符合所研究流域信息管理的特点 ,更能发挥流域水文水情专题GIS管理流域水文水情信息的优势 .

This hydrology GIS for Qingjiang valley was developed by MapObject and VC++. The GIS′s interface was friendly with convenient options and strong functions. The GIS′s functions of querying and managing the spatial information and attribute information were self-contained and powerful, such as hydrology warning, rain warning, flood evaluation and rain evaluation etc. In the design of the GIS′s database, the isomerous data model was used. The GIS can manage the information of Qingjiang valley excellently in the way of organizing data, which is fitter to manage the Qingjiang valley′s information than others.
