Building Web Services from Maritime Foundation Data
Jim Gardiner, United Kingdom Hydrographic Office |
| Maritime Foundation Data (MFD) is the concept developed by the United Kingdom Hydrographic Office (UKHO) to begin to move away from the product orientated approach in the provision of maritime geospatial information (GeoINF) and intelligence (GEOINT). To facilitate this development the UKHO have implemented a test bed for the provision of an array of services including OGC web services, such as CSW, WMS, WFS and WCS. |

The Geospatial Semantic Web as Part of a Geospatial Intelligence Integrated Reference Architecture
Steve Little, Tenet Technology Ltd. |
| The UK Ministry of Defence have contracted TENET Technology to undertake a three year research project, Geospatial Intelligence Integrated Reference Architecture (GI2RA). The research is focussed on developing a coherent and consistent information model to deliver data from different domains to the end user. As part of the research we are investigating the use of the geospatial semantic web to form and distribute geospatial relationships across an inter/intra-net. This paper will summarise the work to-date. |

The GeoXACML Policy Language
Martin Kyle, Sierra Systems, Inc. |
| The Open Geospatial Consortium has recently approved a new standard that defines a language for expressing geographical access control policies. GeoXACML is an extension of the XACML security standard published by OASIS. We will explain the requirements driving the standard, elaborate those requirements through use cases, present the domain model and show how geospatial constraints are encoded in the policy language. We will also show how the standard may be deployed within spatial data infrastructures. |
