Towards a formal classification of generalization operators

Abstract

Classification of generalization operators is one of the challenges in current generalization research in order to provide generalization functionality meaningfully on the web. This paper proposes a classification framework for these operators by integrating the commonly accepted generalization model of Gruenreich with generic geo-data models (ISO 19109 & OGC GO-1 Application Objects). The operators that are classified in our framework are based on literature research and will be classified according to Gruenreich’s model. The impact of the operators will be described by applying these geodata models. Future research will show if the list of operators needs to be extended.
