An important requirement when managing spatio-temporal objects is the support for multiple granularities. In this paper we discuss how the modelling constructs of object data models can be extended for representing and querying multi-granular spatio-temporal objects. In particular, we describe object-oriented formalizations for granularities, granules, and multi-granular values, exploring the issues of value conversions. Furthermore, we formally define an object-oriented multi-granular query language, and discuss the dynamic adapting of multi-granular data. Finally, we illustrate the current open research issues of multi-granular spatio-temporal data handling.||Funding Details:||Science Foundation Ireland ; Irish Research Council for Science, Engineering & Technology||Type of material:||Conference Publication||Publisher:||Springer||Copyright (published version):||Springer-Verlag Berlin Heidelberg 2010||Keywords:||Spatio-temporal multi-granularity;Object oriented models||Subject LCSH:||Object-oriented methods (Computer science)
