This work describes the declaration and enforcement of geospatial access restrictions for the infrastructure of heterogenous and distributed geospatial information objects, as they are accessible via the service-oriented geospatial data infrastructure (GDI). Assuming a valid XML markup of the objects and their geometry using the Geographic Markup Language (GML), which is an international standard of the Open GIS Consortium, Inc. (OGC), a solution is introduced that allows the declaration and enforcement of access restrictions, encoded in GeoXACML. GeoXACML is a geospatial extension to the OASIS standard eXtensible Access Control Markup Language (XACML). Due to the nature of the introduced restrictions, the declaration of access restrictions can result in different kinds of inconsistencies. This work describes a mechanism for the detection and classification of contrary permissions. This work also describes a prototype implementation and an illustrating demonstration.
