A Classification of Analysis Methods for Dynamic Point Objects in Envi- ronmental GIS
نویسنده
چکیده
Mobility is the key to contemporary life. While most research activities during recent years concentrated on the representation and modeling of moving objects within GIS environments, analysis tasks have been sorely neglected, especially in the field of environmental GIS. This paper provides an overview of the sparse analysis methods available for dynamic point objects. The methods are classified in a classification cube investigating analysis properties, scopes and limitations. The methods are classified along the axes number of point objects analyzed, degree of automation in knowledge discovery and type of interaction. Further, current research objectives are reviewed and open issues highlighted.
