Advances in an Event-Based Spatiotemporal Data Modeling

Table 1

Analyzing the characteristics of spatiotemporal objects.

	Geographic object	Dynamic object
Similarities	Independence: spatiotemporal objects are independent of each other
	Atomicity: the components of a spatiotemporal object are not of the same type as itself
	Scope: geographical objects occupy a certain range of space domains, while dynamic objects extend in the time domain
Differences	Can go through changes	Have changes embedded within the object
	Has spatial properties	Has a temporal part
	But no temporal properties exists intact at any point in its life cycle	Cannot be expressed completely for a while in its life cycle
