Description of intrinsic homogenous spatiotemporal processes.

Model diagram	Model characteristics
	Establish the relationship between spatiotemporal process and observation state
Representing complex geographic phenomena in GIS [21]
	Define the five-stage objects of “generation, expansion, stability, weakening, and extinction” to form the expression of process objects
Research on marine spatiotemporal process data model and its prototype system construction [22] Research on process-oriented spatiotemporal data model [23]
	Introduce process operation to formally describe complex spatiotemporal events, with stronger and more standardized description ability
Event‐oriented approaches to geographic phenomena [11]
	Propose three types of processes: discrete, linear, and nonlinear
Research on an improved temporal model based on event-process [24]
