Dual-structured hydrological model and GIS integration method and its implementation
Xiaoxiang Zhang · Journal of Hohai University · 2012
The difference in the objects of hydrological models and a geographic information system(GIS) were analyzed based on systematology and analytics theories.According to the application requirements of hydrological models,hydrology and geography need to be integrated.Based on integration of current hydrological models and the GIS,a new structure with two object entities of hydrology and geography was built with the same geographical space and database.To improve the low interaction efficiency between hydrology and geography objects,a concept of a share structure body was introduced into this double-object entities structure.Then,the integration between hydrological models and the GIS were realized.
