Environmental spatiotemporal data accumulates into big data, 
and the content in the data are far beyond traditional mathematics and statistical modeling.
Data-oriented descriptions of time and space phenomena are then constructed
How to master and clarify the concept of data fusion environmental spatiotemporal big data?
By observing various data sources, we will use spatio-temporal data such as detection and social exploration to explore the basis of people and 
the environment (between land, air and water), combined with remote  and social sensing data, to establish multi-space-time research data, and to establish 
multi-dimension of space-time to understand the migration of activities and environmental changes.
