| Abstract: | The arrival of the big data age is changing the way people thinking,working and living.This paper analyzes the current situation of big data and its application,which puts forward the concept of spatio-temporal big data and thinks that the spatio-temporal big data is the fusion of spatio-temporal data and big data.This paper also analyzes the changes of science paradigms,spatio-temporal information transmission and cognitive model brought by spatio-temporal big data,which based on the background,characteristics,nature and type of big and spatio-temporal big data.Meanwhile,the theoretical,technical and product systems are discussed. |
