Abstract

‘Today, we observe a wide use of geospatial databases that are
implemented in many forms (e.g. transactional centralized systems, distributed databases, multidimensional datacubes). Among those possibilities, the
multidimensional datacube is more appropriate to support interactive analysis
and to guide the organizationÂ’s strategic decisions, especially when different
epochs and levels of information granularity are involved. However, one may
need to use several geospatial multidimensional datacubes which may be
heterogeneous in design or content. Overcoming the heterogeneity problems in
a manner that is transparent to users has been the principal aim of
interoperability for the last fifteen years. In spite of successful initiatives and
widespread use of standards, today »s solutions do not address yet geospatial
datacubes. This paper aims at describing the interoperability of geospatial
datacubes, defining the semantic heterogeneity problems that may occur when
using different geospatial datacubes, and proposing a conceptual framework to
support semantic interoperability of these datacubes.’
