Spatio-temporal data visualization analysis method and system based on layer layout

Abstract

The invention discloses a spatio-temporal data visualization analysis method and system based on layer layout. The spatio-temporal data visualization analysis system comprises a multimedia uploading and management unit, a view model creation unit, a view model management unit, a visualization interface management unit and a database management unit. According to the invention, decoupling of the visual interface and the view is realized; all view models can be shared and reused in different visual interfaces or different layers of the same visual interface in an instance form; the visual interface performs layout of one or more view model instances in a layer form, a user can subscribe linkage events of the view model instances according to actual requirements, and multiple linkage combination effects are self-defined. A combined interaction network, layout layer management control and automatic data updating are combined to carry out spatio-temporal data visualization analysis, a graphlevel interaction analysis mode is provided for visualization analysis oriented to different business topics, and the use efficiency and the comprehensive presentation capability of a spatio-temporalvisualization interface are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of data visualization analysis, and in particular relates to a layer layout-based spatio-temporal data visualization analysis method and system. Background technique [0002] With the development of technologies such as the Internet of Things, cloud computing, and big data, sensor networks all over the city are acquiring and transmitting extremely large amounts of data all the time. Features of linearity and rapid change. At the same time, with the advancement of smart city construction, barriers between data departments and industries are gradually broken down, and data sharing has become the general trend. In this context, the amount of data in various business systems continues to increase, and traditional data representations such as text, spreadsheets, and charts are difficult to fully express the hidden information and internal connections of massive data, and data visualization analysis technology ha...

AI Technical Summary

Problems solved by technology

[0003] 1. Business-oriented customized development, the view and the visual interface are strongly coupled and associated, and it does not support the reuse and independent editing of views in different visual interfaces, and the utilization rate of completed views is not high;

[0004] 2. Switching between interfaces usually adopts multi-interface display or carousel switching display mode, does not support partial sharing or partial switching of the interface, and the utilization rate of the completed interface is not high;

[0005] 3. The linkage configuration is not flexible enough, and the custom combination configuration and linkage of views and interaction events cannot be performed based on the interaction rule network
