Problems solved by technology

Diversified urban heterogeneous data, due to their original application scenarios and related production requirements, are poorly displayed under a unified platform and do not meet the requirements of relevant specifications. Therefore, relevant governance of the data is required; In other words, the cost of use is increased, and different types of data cannot be effectively managed in one platform

Abstract

The invention discloses a method for constructing a multi-layer city model through multi-source data fusion. The method comprises the following steps: acquiring original model data; determining the data category of the original model data according to the source of the original model data; preprocessing the original model data to obtain preprocessed model data; converting the data format of the preprocessed model data into a unified data format, determining LOD data classification according to the application scene of the preprocessed model data, and obtaining a model data file cluster; hosting a model data file cluster; and classifying and binding the hosted model data file clusters according to layer attributes. According to the method, a multi-source heterogeneous data fusion method is established for different model data systems, and homologous data and related treatment methods are provided for urban data treatment, urban dynamic transition research and CIM application.

Description

technical field [0001] The invention relates to the technical field of city models, in particular to a method for building a multi-layer city model through multi-source data fusion. Background technique [0002] City Information Modeling (CIM) is based on Building Information Modeling (Building Information Modeling, BIM), Geographic Information System (Geographic Information System, GIS), Internet of Things (Internet of Things, IoT) and other technologies. Underground, indoor and outdoor, historical status and future multi-dimensional and multi-scale information model data and urban perception data, construct an organic complex of urban information in three-dimensional digital space. Diversified urban heterogeneous data, due to their original application scenarios and related production requirements, are poorly displayed under a unified platform and do not meet the requirements of relevant specifications. Therefore, relevant governance of the data is required; In other word...
