Representing, storing and mining moving objects data

Abstract

Data about moving objects have been collected in huge amounts due to the proliferation of mobile devices, which capture the position of objects over time. Studies about moving objects have been developed as a specific research area of Geographic Information Systems. Those systems are designed to process traditional, static or slowly changing, geospatial data. However, moving objects have inherent a dynamism that requires different approaches to data storage and analysis. This paper presents a review of the key concepts associated to moving objects and their characteristics, as well as the approaches proposed to store data about moving objects. For the analysis of moving objects, an overview of the existing data mining techniques and some future guidelines are also presented.
