  27. Type Dictionary Catalogue Application object object object object object object object object object object Service Library Spatial Object Database = Business Objects CGDI Components Business Objects are organized into collections which form Components Lists Services and Spatial Databases Describe Spatial Database and Service Models Contains functions that act on Objects Contains Spatial Objects .

  28. object object object object object object object object Service Library Spatial Object Database Multiple Component Instances CGDI will have many instances of these components Type Dictionary Catalogue e.g. different Catalogues and Dictionaries for different information communities e.g. • Coordinate Transformation Services • Routing Services • Overlay Services e.g. • Geographic Features • Coverages • Reference Systems • Events • Projects .

  29. object object object object object object object object Component Interfaces Interfaces provide access to Components and their Objects Type Dictionary Catalogue e.g. Get Schema (name) e.g. Find Database (a1.. an) e. g. Invoke Service (name, p1 .. pn) e.g. Get Feature (p1, p2, p3, p4) Service Library Spatial Object Database Common components and objects need standardized interfaces .

  38. Part 3 -- Implementation Plan “How do we build CGDI?” .

  39. Reference Architecture, Standards, Open Specifications, Today -- nucleus for CGDI Design 2 years -- core CGDI 5 years -- self-sustaining CGDI 10 years -- ubiquitous CGDI Build Components Applications Integrate Prepare Data Implementation Strategy 1. Establish a CGDI nucleus 2. Incrementally build up by pursuing opportunities along several fronts 3. Follow a spiral development approach Analyze .

  40. CGDI Systems Engineering Approach Balance top-down and bottom-up approaches to achieve greatest success Top DownDrive CGDI development from application needs e.g.• Sustainable Development• Transportation Planning• Climate Change Monitoring• Disaster Response• Site Assessment ... i.e. Wrap existing applications, data and services with CGDI compliant interfaces Bottom UpMaximize leveraging of existing data and systems .

  41. Standard CGDI Component Abstractions Standard Catalogue Interfaces Spatial Database Interfaces Standard Dictionary Interfaces Service Library Interfaces Specific ServiceLibraries and Services Specific types of Dictionariesand Descriptions Specific types of Cataloguesand Descriptions Specific types of Spatial Objects and Interfaces Development of the Reference Architecture A sustained effort to develop the Reference Architecture is crucial 1. Get agreement on Reference Architecture Components 2. Get agreement on top-level Component Interfaces 3. Define specialized Components, Business Objects and Interfaces .

  42. Reference Architecture Select appropriate standards ImplementedOpenSpecifications Components Identify participating components Establish the CGDI Nucleus Use the Reference Architecture as a guide • Catalogues• Spatial Databases• Service Libraries• Dictionaries e.g.• FGDC Content Standard for Digital Geospatial Metadata• FGDC GEO/Z39.50 Search Protocol• OGC Web Mapping Specification Interfaces ... e.g.• CSDGM Compliant Catalogues• FGDC GEO/Z39.50 Enabled Spatial Databases• OGC WMSI Services ... .

  43. 1. Vision / Reference Architecture Objective: get agreement on vision development process and vision Publish initial version online Continue process of refinement and publication Two Year Plan -- Part 1 2. Applications Objective: create some “killer applications” • Model a few key application domains with domain experts from relevant application panels • Identify common geospatial needs across models and map to Components, Objects and Interfaces in the CGDI Reference Architecture • Begin building identified operational infrastructure that will support the building of applications .

  44. 3. Data Objective: build a critical mass of online, accessible geospatial data Get Framework Data online In forms that can be used for purposes of Discovery and Integration Framework databases must be queryable by name or by spatial region Wrap legacy systems with open interfaces for data discovery / access Build and use toolkits to simplify wrapping of legacy systems Develop better (open) interfaces for data access Two Year Plan -- Part 2 4. Catalogues Objective: make applications, data and services discoverable • Establish online Catalogues for CGDI-based applications, CGDI databases, and online services • Facilitate populating of Catalogues with descriptions • Wrap existing Catalogues with open interfaces • Establish gateways between peer Catalogues in CGDI .

  45. 7. Standards Objective: to get standards in place for core CGDI components Publish online guide of CGDI endorsed geospatial standards Work out new CGDI component and interface specifications in concert with Standards bodies Two Year Plan -- Part 3 5. Services Objective: to provide services that enrich online access • Develop Visualization Services • Develop Data Integration Services 6. Relationships Objective: to enable referencing to Framework Data • Develop Relationship Services • Develop Feature Relationship Dictionary .

  46. Reference Architecture Continued refinement will result in standard interfaces being published for all major spatial objects and CGDI components. Longer Term View -- 5 years and out • Applications • Development using CGDI will be common place • Components, Business Objects and Interfaces • More kinds of components and business objects will emerge • More sophisticated kinds of interfaces will be available • Specific development objectives • More sophisticated integration capabilities • Collaborative capabilities • Online dictionaries describing component and interface semantics • Tools for rapidly building CGDI applications • Seamless integration with regional SDIs • Seamless integration with international SDIs .
