Research on Muli-source Heterogeneous Data Fusion Based on Geocoding
In order to solve the integration of information resources from different industries and realize the sharing of data in various in-dustries in smart cities,this paper proposes a data fusion method based on geocoding. The method matches two different types of government data,one with spatial coordinates and the other with only location descriptions. Key technologies such as partition unit calculation,hierarchical segmentation geocoding database construction,and text fuzzy matching are proposed to improve the efficiency and accuracy of geocoding. The method is applied in the construction project of the Smart Chengdu,proving that it can effectively improve the efficiency and accuracy of matc-hing and achieve efficient fusion of multi-source,heterogeneous,and massive government data.
