What is PD CEN/TR 15449-4 - Spatial Data Infrastructure about?
PD CEN/TR 15449-4 is the fourth part of the multiple series document that 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 PD CEN/TR 15449-4 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 familiarize themselves with geographic information and SDI concepts, and standards developers and writers.

Why should you use PD CEN/TR 15449-4 - Spatial Data Infrastructure?
Spatial Data Infrastructure (SDI) is a general term for the computerized environment for handling data that relates to a position on or near the surface of the earth. It may be defined in a range of ways, in different circumstances, from the local up to the global level.
PD CEN/TR 15449-4 specifies five viewpoints for SDI i.e.:
- The enterprise viewpoint - service aspects from an organizational, business and user perspective
- The computational viewpoint - service aspect from a system architect perspective
- The information viewpoint - service aspects from a geospatial information expert perspective
- The engineering viewpoint - service aspects from a system designer perspective
- The technology viewpoint - service aspects from a system builder and implementer perspective
PD CEN/TR 15449-4 addresses the concepts of service specifications and the methodology for developing service specifications through the application of the relevant International Standards based on RM-ODP. The architecture is a set of components, connections and topologies defined through a series of viewpoints. The purpose of the architecture is to provide a description of the system from multiple viewpoints. Also, the architecture helps to ensure that each viewpoint will be consistent with the requirements and with the other viewpoints.
