Abstract
This section describes the requirements which we have to take into account with regard to the annotation and querying of spatial information sources. Following, we discuss how our qualitative abstraction of space is represented. Spatial relevance is an important feature concerning neighborhood and partonomic distance. This is discussed in the following subsection and demonstrate the performance of this approach with examples.
This chapter summarizes ideas that have been published elsewhere [113,128,121,133,120]. The first ideas and the polygonal representation have been introduced in [112,99]. The fundamental ideas behind the components and the functionality of the spatial reasoner have also been extensively discussed with Thomas Vögele and Christoph Schlieder.
