Multi-Source Data Fusion Pretreatment
System in Distributed Hydrological Models
Abstract: Multi-source data fusion pretreatment system which is based on vast digital information, meteorological and hydrological monitoring data and so on is put forward for standardization and modularization needs of multi-purpose distributed hydrological models. The dynamic connection of spatial data and attribute data is created based on a four-level division framework of watershed. Besides, it also achieves seamless connections between GPS, GIS, RS systems and hydrological models from grid level to basin level, and can be quickly applied to different hydrological models. The system is used to build spatial information and topological relationship of distributed and semi-distributed hydrological models in Yangtze estuary, which suggests its convenience and adaptation.
