PD CEN/TR 15449-2:2012CEN/TR 15449-2:2012 (E) 5 Introduction Spatial data infrastructure (SDI) is a general term for the computerised 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,

19、 in different circumstances, from the local up to the global level. This Technical Report focuses on the technical aspects of SDIs, thereby limiting the term SDI to mean an implementation neutral technological infrastructure for geospatial data and services, based upon standards and specifications.

20、It does not consider an SDI as a carefully designed and dedicated information system; rather, it is viewed as a collaborative framework of disparate information systems that contain resources that stakeholders desire to share. The common denominator of SDI resources, which can be data or services, i

21、s their spatial nature. It is understood that the framework is in constant evolution, and that therefore the requirements for standards and specifications supporting SDI implementations evolve continuously. SDIs are becoming more and more linked and integrated with systems developed in the context o

22、f e-Government. Important drivers for this evolution are the Digital Agenda for Europe, and related policies. This Technical Report takes these developments into account. By sharing emerging requirements at an early stage with the standardization bodies, users of SDIs can help influence the revision

23、 of existing or the conception of new standards. The users of an SDI are considered to be those individuals or organisations that, in the context of their business processes, need to share and access geo-resources in a meaningful and sustainable way. Based on platform- and vendor-neutral standards a

24、nd specifications, an SDI aims at assisting organisations and individuals in publishing, finding, delivering, and eventually, using geographic information and services over the internet across borders of information communities in a more cost-effective manner. Considering the complexity of the subje

25、ct and the need to capture and formalize different conceptual and modelling views, CEN/TR 15449 is comprised of multiple parts: Part 1: Reference model: this provides a general context model for the other Parts, applying general IT architecture standards; Part 2: Best practices: this provides best p

26、ractices guidance for implementing SDI, through the evaluation of the projects in the frame of the European Union funding programmes; Part 3: Data centric view: this addresses concerns related to the data, which includes application schemas and metadata; Part 4: Service centric view (in preparation)

27、: this includes the taxonomy of services, concepts of interoperability, service architecture, service catalogue, and the underlying IT standards. Further parts may be created in the future. PD CEN/TR 15449-2:2012CEN/TR 15449-2:2012 (E) 6 1 Scope This part of the Technical Report provides best practi

28、ces regarding Spatial Data Infrastructures (SDIs), referencing to the outcomes of the projects in the frame of the European Union funding programmes. It summarises the deliverables of projects, structured according to the reference model defined in Part 1 of this Technical Report, to be made availab

29、le in an on-line repository where the relevant outcomes are collected and classified in order to provide a structured sets of recommendations for implementing SDIs at the European, national and sub-national levels. This collection refers mainly to the projects funded by the European Union funding pr

30、ogrammes: this choice is driven by the wide vision and analysis which such kind of projects can provide and the wide numbers of stakeholders which have been involved. The outcomes delivered by these relevant practices are collected into a document registry available through the CEN/TC 287 web site.

31、This part of the Technical Report defines the processes and the content of these projects and documents registries, which will help making them more accessible and re-usable. It provides the relevant project deliverables addressing the main SDI issues as described in the other parts of this Technica

32、l Report. The intended readership of this Technical Report are 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

33、 SDI concepts, and standards developers and writers. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

In addition there are projects that help linking standards development to the implementation of legal acts and policies. In particular for the outcomes and best practices of projects that are not directly involved in

42、the standards development processes, it is paramount that their efforts be captured and made sustainable beyond the lifetime of the projects. With INSPIRE1), GEOSS2)and GMES3)now well established, numerous projects and activities that are (co-)funded by EU programmes are being asked to use or build

43、upon standards and specifications in the domain of geographic information. Design methodologies, reference models, good practices in UML data model design and data model transformation, as well as standards for various services are examples of topics that are being or that have been addressed by doz

44、ens of European Union-funded projects. The paymasters and the consortia that developed these products have made investments that should be protected. The GIGAS4)project (GEOSS, INSPIRE and GMES, an Action in Support), financed by the Directorate General Information Society of the European Commission

45、, has made concrete recommendations on how this could be done. In particular, a role is proposed for CEN/TC 287 Geographic Information to maintain relevant deliverables or parts thereof, not only of the GIGAS project, but also of other EU-funded projects. This is to lead to a formal EU-level reposit

46、ory of reference material on interoperability, where future projects can find state-of-the-art information on interoperability. At the same token, these projects could then add new reference material as they progress in their work programmes. This part of the Technical Report, along with the CEN/TC

47、287 document registry, constitutes the backbone for making the outcomes and best practices of projects sustainable. 5.2 Categories of contribution 5.2.1 Content classification The general issue is knowledge management related to standardization processes in projects funded by the European Union prog

48、rammes. More specifically, the proposed relevant practices should support the analysis of project outcomes, which in the majority of the case are documents, but it can be also IT tools, infrastructure and datasets. The core goal of this repository is strictly limited in the setup of a document regis

49、try related to the relevant outcomes of European Union funded projects. Additional extension of this registry to manage references to outcomes different from the documents will be taken into account in the future release. The content managed by this registry can be categorized according to different aspects, applying a faceted c
