Embodiment Construction

[0027] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0028] The urban multi-source heterogeneous data involved in this technical solution covers all available data generated in the operation of the city, including various real-time access sensor data, map data, remote sensing image data and information indirectly generated, as well as various government departments Collection and statistics of urban fundamental data, statistical data, as well as urban traffic flow data, air quality data, meteorological data, remote sensing image data, POI distribution data, land use data, etc. These data come from different sources, have various formats, and have different time and space precision. Therefore, before these data are used in complex operations such as deep learning, they need to be normal...

Abstract

The invention discloses a method for constructing a city image based on city multisource heterogeneous data. The method comprises the steps of firstly obtaining original data from a city multisource heterogeneous data interface, and releasing the data to a specified internal classification of a message queue; secondly establishing a data rasterization conversion module corresponding to the city multisource heterogeneous data, extracting the data from the internal classification of the message queue, and performing rasterization conversion and data supplementation on the extracted data by adopting corresponding algorithms according to a normalized raster data model and original structures, business characteristics and time-space attributes of the data; and thirdly storing raster data formedafter the rasterization conversion and the data supplementation in a target database designed according to the normalized raster data model, and forming the city image composed of the city multisource heterogeneous data. According to the method, the multisource heterogeneous data in a city space is mapped to a unified and regular raster space, so that associated fusion of the heterogeneous data is realized, and basic data can be provided for specific application of a smart city.

Description

technical field [0001] The invention belongs to the technical field of big data processing, and in particular relates to a method for constructing a city portrait based on multi-source heterogeneous data of the city. Background technique [0002] At present, urban development is facing challenges such as population expansion, environmental degradation, frequent public health incidents, traffic congestion, and waste of resources. Smart cities are the future development trend. [0003] Smart city refers to the combination of information technology and the Internet, through various intelligent applications, to improve the operational efficiency of urban infrastructure, improve the level of urban operation management and public services, and make people's lives better. In the construction and management of smart cities, technologies such as the Internet of Things, cloud computing, and big data are playing an increasingly important role. In smart cities, due to the adoption of I...
