2 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.2 The OpenGIS Consortium Vision A world in which everyone benefits from geographic information and services made available across any network, application, or platform.

3 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.3 What is OGC? The Open GIS Consortium (OGC) –Not-for-profit, international consortium –250+ industry, government, & university members Specification Development Program - Committee process similar to other industry consortia and SDOs (W3C, OMG, ISO, CEN). Interoperability Program - Testbeds, pilot projects etc. to develop and test OpenGIS Specifications and help bring conformant products to market. Outreach and Community Adoption Program – Education, training and outreach to encourage the use of products with OpenGIS interfaces. Includes business development services for our members. OGC Mission Our core mission is to deliver interface specifications that are openly available for global use.

4 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.4 Our goal is … …improve public and private sector organizations ability to author, publish, share, and use geospatial information in… Neighborhoods, Communities, Localities, Provinces, Nations, Regions, … the World

6 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.6 Conceptual Model Framework for next-generation vendor-neutral distributed geoprocessing and location systems Flexible future applications assembled from multiple, network- enabled geoprocessing and location services Integrate with Web Services technologies Foundate Information Interoperability Reduce barriers between real world, information about the real world, and distributed users

7 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.7 OGCs Iterative Development Process Focus on Distributed Systems Engineering Yields Tested Engineering Specifications, Information Infrastructures, Prototype Implementations OGC Interoperability Program OGC Specification Program OGC Outreach Program Draft Engineering Specifications Adopted Specifications Holes and Enhancements SCOTS Implementations Prototype Implementations Requirements Distributed Systems

8 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.8 Standards and Specifications are Important to Interoperability Standards enable the one-to- many character of a network. When they work, you may not notice them. Advances in technology drive the need for standards and interoperability. For example: –Standard Time came from the railroad industry. –The Internet is built on standards (TCP/IP). –World Wide Web is built on standards Standards (HTTP/XML). Geospatial Interoperability means spatial systems can work together to meet market needs.

9 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.9 Market Signals Diminishing use of the term Geographic Information System Increasing use of spatially enabled enterprise services, location services and location-based services. Geographic processing is no longer isolated. Geographic information services support business processes throughout an enterprise - decision support, route planning, analysis tools, geocoding, gazetteer services, geoparsing, proximity determination, locating points of customer service…

10 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.10 Addressing Market Requirements Users want to blend spatial technology with classic information technology (IT) topics like security, authentication real-time requirements process chaining accuracy, time and timeliness multi-use information persistence, revision and versioning business objects and their rules upward compatibility…..

11 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.11 Domains are Changing Requirements Traditional map makers, photo interpreters, surveyors, and GIS analysts benefit from automated tools, better access to data, more data, improved means of distribution, etc. Judgment and training remain essential in creating spatial information products. Expanding Spatial Data Infrastructures put spatial information products – and raw data and tools – into the hands of –More people in traditional user domains: planning, resource management, utilities, agriculture etc. –People in new user domains: risk management, e-Gov, first responders, customer support, logistics, insurance, etc.

12 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.12 Why is Interoperability Important to Spatial Data Infrastructure? People care about SDI because they need information. –Networks supply more information than islands of automation. Resources are limited. –Both data and software tend to become less expensive through interoperability. Finding useful data has been difficult. –Digital catalogs support much faster discovery, assessment and access by individuals. Geoprocessing software has been expensive. –The component paradigm and Web Services paradigm save save society time and money. Sharing data reduces redundant efforts, but sharing has been difficult. –Technical interoperability gives users Web-direct views into online data sets, and Web-direct access to the real data, usually eliminating the need for batch transfers and batch conversions. –XML will be helpful in overcoming semantic non-interoperability at the human and machine levels.

27 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.27 OpenGIS Reference Model (ORM) The ORM is based on the Reference Model for Open Distributed Processing (RM-ODP, ISO/IEC 10746), a widely used methodology for architecting open, distributed processing systems. The ORM helps you develop a clear and detailed idea about what you want to do, then helps you design an architecture and implementation strategy. The ORM documents the OGC technology baseline in terms of enterprise, information, and technology view points. INSPIRE and GOS and their component enterprise systems will have multiple users, developers, operators, and reviewers, each viewing the system from their own viewpoint. The ORM helps ensure that each view will be consistent with the overall requirements and with the other views. The ORM provides examples.

41 Helping the World to Communicate Geographically © 2003, Open GIS Consortium, Inc.41 Focus and Direction Focus: the interoperability of geospatial and location-based systems. Funded by members to eliminate non-interoperability pain points in the market through 1) rapid specification development and 2) prompt implementation of these specifications in Standardized Commercial Off-The-Shelf (SCOTS) products. –Technology users 1) set requirements for specifications, then 2) require that products they will purchase must implement these specifications. –OGC coordinates with standards bodies and other standards consortia. OGC enables interoperability of tightly coupled geospatial components on a single CPU, tightly coupled system integration across a local network, and loosely coupled messaging interoperability – OGC Web Services.
