【Abstract】 On the basis of the analysis of the rain condition and water regimen geographical database system, the visual analyzing system of Jiangsu real-time water regimen is established. The paper describes the design of the visual analyzing system, its structure, work flow, content, and function.The visual analyzing system, which is developed by using MapBasic developing language and with the support of Maplnfo 5.5, can visualize rain condition and water regimen on the electronic map through access to the real-time water regimen SYBASE database and data processing, so as to make a real-time reflection on the rules of the distribution of rain condition and water regimen. Moreover, it can provide visualization map of rainstorm distribution, rainfall isopleth, as well as statistics and analysis of rainstorm features. In addition, the system can provide comparison and analysis of the present characteristic values of real-time rain condition and water regimen versus those in the past in order to provide a scientific basis for the decision-making of flood control.更多还原
