Research on Key Technologies of the Smart City Spatio-temporal Big Data Platform
As a hub for sharing and exchanging urban spatial and temporal basic data,the spatio-temporal big data platform serves as a vehicle for delivering secure,unified,authoritative,and reliable geographic information services to government departments,enterprises,institutions,and the public.After years of development and promotion,industry applications built on the spatio-temporal big data platform have flourished,the value of the urban spatial infrastructure has been fully leveraged.In the process of application,the spatio-temporal big data platform gradually reveals issues with low efficiency in updating and rendering geographic elements with large volumes of data,and the inability to dynamically perform fine-grained control in spatial data sharing.This article,aligned with business needs,summarizes the experience of building a smart city spatiotemporal big data platform,and conducts research on vector slicing technology、service splitting technology based on permission control,offering a practical solution to the fundamental and common issues encountered during the development of a smart city spatiotemporal big data platform.
