24、nization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establis

25、hed has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization

26、. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. P

27、ublication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Ava

28、ilable Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between

29、the members of a technical committee and is accepted for publication if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an Internation

30、al Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is drawn to the possibility that some of the elements of this document may be the

ISO/TS 19101-2 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics. ISO 19101 consists of the following parts, under the general title Geographic information Refere

33、ntroduction This Technical Specification provides a reference model for processing of geographic imagery which is frequently done in open distributed manners. The motivating themes addressed in this reference model are given below. In terms of volume, imagery is the dominant form of geographic infor

34、mation. Stored geographic imagery volume will grow to the order of an exabyte. National imagery archives are multiple petabytes in size; ingesting a terabyte per day. Individual application data centers are archiving hundreds of terabytes of imagery. Tens of thousands of datasets have been catalogue

35、d but are not yet online. Large volumes of geographic imagery will not be portrayed directly by humans. Human attention is the scarce resource, and is insufficient to view petabytes of data. Semantic processing will be required: for example, automatic detection of features; data mining based on geog

36、raphic concepts. Information technology allows the sharing of geographic information products through processing of geographic imagery. Standards are needed to increase creation of products. A number of existing standards are used for the exchange of geographic imagery. Examples of technical, legal,

37、 and administrative hurdles to moving imagery online include technical issues of accessibility geocoding, geographic access standards, maintenance of intellectual property rights, maintenance of individual privacy rights as resolution increases, and technical issues of compatibility requiring standa

38、rds. Governments have been the predominant suppliers of remotely sensed data in the past. This is changing with the commercialization of remotely sensed data acquisition. Geographic imagery is a key input to decision support for policy makers. The ultimate challenge is to enable the geographic image

39、ry collected from different sources to become an integrated digital representation of the Earth widely accessible for humanitys critical decisions. Currently a large number of standards exist that describe imagery data. The processing of imagery across multiple organizations and information technolo

40、gies (IT) is hampered by the lack of a common abstract architecture. The establishment of a common framework will foster convergence at the framework level. In the future, multiple implementation standards are needed for data format and service interoperability to carry out the architecture defined

41、in this Technical Specification. The objective of this Technical Specification is the coordinated development of standards that allow the benefits of distributed geographic image processing to be realized in an environment of heterogeneous IT resources and multiple organizational domains. An underly

42、ing assumption is that uncoordinated standardization activities made without a plan cannot be united under the necessary framework. This Technical Specification provides a reference model for the processing of geographic imagery which is frequently done in open distributed manners. The basis for def

43、ining an information system in this SANS 19102-2:2009This s tandard may only be used and printed by approved subscription and freemailing clients of the SABS .ISO/TS 19101-2:2008(E) ISO 2008 All rights reserved viiTechnical Specification is the Reference Model for Open Distributed Processing (RM-ODP

44、) 78. A brief description of RM-ODP can be referenced in Annex B. The basis for defining geographic information in this specification is the ISO 19100 family of standards. The RM-ODP 78viewpoints are used in the following fashion: Typical users and their business activities, and policies to carry ou

45、t those activities, are addressed in the Enterprise Viewpoint. Data structures and the progressive addition of value to the resulting products are found in the schemas of the Information Viewpoint. Individual processing services and the chaining of services are addressed in the Computational Viewpoi

46、nt. Approaches to deploy the components of the Information and Computational viewpoints to distributed physical locations are addressed in the Engineering Viewpoint.
