Spatio-temporal big data and spatio-temporal Internet: new directions for future technological development

1 Introduction to the concept

spatio-temporal big dataIt refers to massive data characterized by temporal and spatial dimensions, which include spatial locations, time series, attribute values, etc. spatio-temporalBig DataCharacterized by the "4Vs", i.e., large volume, high dimensionality, low value density, and value diversification.

spacetime InternetIt is a new type of Internet based on spatio-temporal big data, the core of which is to realize the ubiquitous perception, real-time transmission, efficient processing and intelligent application of spatio-temporal information. Spatio-temporal Internet has the characteristics of "3C", i.e. connection, computation and perception.
