Abstract
The enormous importance that has the analysis of the movement semantics and it application in many fields has been fully demonstrated, with tremendous importance in GIS domain, examples are [1,2]. More and more researches and proposals are considering aspects related to moving objects. From a semantic perspective, researchers have identified three groups of moving objects: moving points (e.g. persons, cars, planes), moving regions (e.g. fire regions, lakes) and moving lines (trains, convoys). More efforts have been focused in the analysis of the semantics of moving points, few more about moving regions and no known approaches, or just too few, consider moving lines. The objective of this work is not abolishing the usage of moving points and moving regions, but to demonstrate that moving lines should also be considered for enhancing the analysis in several situations.
