16 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 the concept of communication (example)

17 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 the concept of communication (example)

18 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 the concept of communication

19 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 the concept of communication

20 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 GSDI Spatial Data Infrastructure

21 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 ontology and GSDI Until approx. 1990

22 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 ontology and GSDI

23 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 meaning ontology and GSDI

24 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Cross section ontology and GSDI

25 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 GSDI

26 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 The active components in SDI: International Organizations like UN, NATO etc. Governments National Mapping Agencies Standardization bodies Custodians for various services Active and passive components in GSDI

27 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 The passive components in Geospatial Infrastructure: Legislation Collaboration (MoUs) Standards Models Specifications Services Geo-information (data) (here presented in their mutual dependency) Active and passive components in GSDI

28 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Legislation is … made by the active components enacting the framework for the deeper structures of geo- communication setting the areas of responsibility 1.Legislation 2.Collaboration (MoUs) 3.Standards 4.Models 5.Specifications 6.Services 7.Geo-information (data) Active and passive components in GSDI

29 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Within the framework of legislation operational partnerships must be established. MoUs express intentions Setting the area(s) of interest MoUs must cover all areas of interest Collaboration must cover agreements upon sharing information over services and registries Collaboration (MoUs) 1.Legislation 2.Collaboration (MoUs) 3.Standards 4.Models 5.Specifications 6.Services 7.Geo-information (data) Active and passive components in GSDI

30 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Standards Collaborations are policy statements (position paper). MoUs do not say anything about the work items. Standards are a kind of agreement on 'What are we going to work on? How do we define our activities?' Standards are general. Therefore they can be used for several concrete projects. Specifications are concrete, and are valid for one project. 1.Legislation 2.Collaboration (MoUs) 3.Standards 4.Models 5.Specifications 6.Services 7.Geo-information (data) Active and passive components in GSDI

31 Geo-communication and GSDI Aalborg University Lars Brodersen 2007

32 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Models Models describe, how given standards have to be used for a certain project. Models bridge the gap between standards and specifications. Value Model - Identification of content Business process engineering: - Information and resource flow - Requirements driven service development System Use Case: - Application schemas - (General) Feature models 1.Legislation 2.Collaboration (MoUs) 3.Standards 4.Models 5.Specifications 6.Services 7.Geo-information (data) Active and passive components in GSDI

33 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Specifications define what should be done in a given, concrete project according to a certain standard Specifications contain rules for action (behavior) for a given project Specifications define the content (both system and information) for at given project Specifications 1.Legislation 2.Collaboration (MoUs) 3.Standards 4.Models 5.Specifications 6.Services 7.Geo-information (data) Active and passive components in GSDI

34 Geo-communication and GSDI Aalborg University Lars Brodersen Legislation 2.Collaboration (MoUs) 3.Standards 4.Models 5.Specifications 6.Services 7.Geo-information (data) Services Services are the concrete, practical set-up of the passive components (no. 1 to 5). All passive components no. 1 to 5 can all be carried out on a piece of paper; nothing practical has happened until then. Services establish the technology, i.e. software, hardware, user-interfaces etc. Active and passive components in GSDI

35 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Metadata and information - Metadata and information are the 'fuel' for the machinery (the services) once these have been created. -Metadata and information are not technology! -Metadata and information are the actual, practical, concrete result of a given production, which has been carried out in accordance with the characteristics of the services, with the specifications, with the models, with the standards, with the MoUs and in accordance with the legislation. 1.Legislation 2.Collaboration (MoUs) 3.Standards 4.Models 5.Specifications 6.Services 7.Geo-information (data) Active and passive components in GSDI

36 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Cross section ontology and GSDI

37 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Information design

38 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 ontology and information design

39 Geo-communication and GSDI Aalborg University Lars Brodersen twelve good colours ontology and information design

40 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 NOTHING ! twelve good colours scales lines ontology and information design

41 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Does it make sense to say: ”I need a building of 188 m 2 ” Answer: What sort of building do you need? (and the answer to that question depends entirely on the usage) ontology and information design

42 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 ontology and information design

43 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Firstness Thirdness Secondness

44 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 the concept of communication

45 Geo-communication and GSDI Aalborg University Lars Brodersen 2007 Geo-communication bridges the gap between reality and action
