Integration Technology Of Multi-modal Spatio-temporal Data Visual Analysis System For Client

With the rapid development of computer science and technology,information and communication technologies such as sensor networks,Internet of Things,and social networks are quickly integrated into people's lives,making it more and more easy to obtain spatiotemporal data describing the three-dimensional world of human-machine-things.The scale of the obtained spatio-temporal data is increasing day by day,and the semantic information of the spatio-temporal data is also becoming richer,prompting people to pay more and more attention to the analysis and expression of spatio-temporal data.The main data processed by the traditional spatial information system is the point,line,and volume vector data in the physical space,as well as some attribute data related to the vector data.However,the spatiotemporal data to be processed by the new generation of spatial information system includes not only real photos,videos,and textures.Data such as materials and materials also contain abstract expressions such as symbols,calculations,and simulation results.They have typical multimodal characteristics.At present,the visualization and analysis of multimodal spatiotemporal data has become a hot frontier in academia and industry.The rapid development of mobile Internet has also promoted the diversification of terminals for users to access the Internet.The device performance,screen size,and interactive operation modes of different terminals are very different.The multi-modal spatio-temporal data visual analysis system has distinct operating mechanisms and technical characteristics on independent desktops,network servers,and network clients.This article is mainly geared towards the needs of users with diverse terminals.For the desktop client,a plug-in development method and layered architecture technology are proposed to achieve high expansion and reusability of the client's business functions.For the web client,a micro frontend architecture and component development technology are proposed to achieve agile development of the front end.This article combines an example(complete the integration of the client multi-modal spatio-temporal data visual analysis system and visual analysis module),introduces the application of plug-in development based on the micro service architecture in the prototype of the full space information system,and shows the micro service Framework and plug-in development combine flexibility and efficiency in system integration..
