Abstract
In this paper, we present a differential change-oriented model for the storage and communication of spatio-temporal information. The focus is on the development of model primitives and operators to support the aggregation of change over time and the propagation of change across resolution. Our investigation is motivated by recent advances in image-based geospatial databases, with constantly increasing update frequencies, and diverse user communities performing queries of various levels of detail. The primitives and operators presented here extend existing qualitative operators to support the management of quantitative and geometric information within a change-oriented spatio-temporal environment. We also show how the design of our model results from ‘change semantics’ at different granularities. By doing so, advanced communication operations can be addressed within our model in an efficient way.
