ONR CEN/TR 15449-4

This Technical Report describes a service-centric view of a Spatial Data Infrastructure (SDI). The Service Centric view addresses the concepts of service specifications, the methodology for developing service specifications through the application of the relevant International Standards, and the content of such service specifications described from the perspective of the five Reference Model of Open Distributed Processing (RM-ODP) viewpoints: • the enterprise viewpoint addresses service aspects from an organisational, business and user perspective; • the computational viewpoint addresses service aspects from a system architect perspective; • the information viewpoint addresses service aspects from a geospatial information expert perspective; • the engineering viewpoint addresses service aspects from a system designer perspective; • the technology viewpoint addresses service aspects from a system builder and implementer perspective. The intended readership of this Technical Report is those people who are responsible for creating frameworks for SDI, experts contributing to INSPIRE experts in information and communication technologies and e-government that need to familiarise themselves with geographic information and SDI concepts, and standards developers and writers.
