AN INVESTIGATION OF SEMANTIC, GEOMETRIC AND GRAPHIC HETEROGENEITIES OF BUILDING AND FACILITY OBJECTS IN A MULTI-RESOLUTION SPATIAL DATABASE

Abstract

Various spatial applications usually entail spatial data modelling at different levels of detail (LoDs), points of view (PoVs) and purposes of use (PoUs) as well as spatial data integration from multiple sources. So there is an increasing importance of creating a multi-resolution spatial database for map and geoinformation producers in order to provide more comprehensive location-based services and multiple products more easily towards the increasing demands of society. In this article, multi-resolution spatial data modelling is systematically and briefly described in a broader perspective as well as semantic, geometric and graphic heterogeneities are investigated for selected building and facility objects. Heterogeneous nature of spatial objects in a multi-resolution database is shown for some subclasses of buildings and facilities by the diversity of definitions of same real world phenomena in different aspects.
