Datenunsicherheit in hybriden Geoinformationssystemen

Abstract

An essential requirement for a comprehensive use of hybrid data is the consideration and processing of its uncertainty. Erroneous interpretations of analyses can be avoided if uncertainty is integrated as a mandatory component, stored and considered in all operations. In this contribution, a probabilistic approach is presented for modelling geometrical and thematic uncertainty. The used hybrid data model is extended to manage data uncertainty.
