Use of Open Geospatial Consortium OGC Standards in

Use of Open Geospatial Consortium (OGC) Standards in the Geosciences Tutorial at IGARSS 2010 George Percivall OGC Chief Architect 25 July 2010 Copyright © 2010, Open Geospatial Consortium, Inc.

Use of OGC Standards in the Geosciences • This tutorial will provide an overview of standards from the Open Geospatial Consortium (OGC) and their use in the geosciences. – The OGC is a non-profit, international, voluntary consensus standards organization. • Geosciences have been a main driver for OGC standards. – Concepts from geodesy, remote sensing, metrology, and science informatics were used to define the standards. – The standards have been applied both before and after adoption to the fields of hydrology, geology, meteorology, oceanography, land cover, and many other scientific domains of the geosciences. – Geoscience applications will be presented showing use of OGC standards for data and information discovery, access, processing, fusion and decision-support.

Interoperability allows a Common Reality “What we are doing is facilitating a common picture of reality for different organizations which have different views of the reality, the disaster, the emergency, the catastrophe, that they all have to deal with collectively” David Schell Chairman OGC Copyright © 2009, Open Geospatial Consortium, Inc. , Making Location Count…

What is a standard? • A document, established by consensus and approved by a community using formal processes, that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context. Euro. Control Aeronautical Sky. View 2 application Copyright © 2010, Open Geospatial Consortium, Inc. Making Location Count… 9

What do we mean by “Open” Standard? • Freely and publicly available • Non discriminatory • No license fees • Vendor neutral • Data neutral • Agreed to by a formal consensus process Making Location Count… Copyright © 2009, Open Geospatial Consortium, Inc. ,

Why Open Standards? • Rapidly mobilize new capabilities – plug and play • Lower systems costs • Encourage market competition – Choose based on functionality desired – Avoid “lock in” to a proprietary architecture • Decisions to share information and services become policy decisions Making Location Count… Copyright © 2009, Open Geospatial Consortium, Inc. ,

Benefits - Participation in OGC Programs • Direct, legal, and broad dialog with industry on interoperability needs • Align industry on priority standards needs – User community organizations help to identify and prioritize requirements for new standards. • Improve choice and competition in the marketplace – Involvement in OGC helps create broad industry incentive to advance and implement OGC standards in their products. This increases the pool of standardsbased products that can be plugged into a system or enterprise -- no single application meets the needs of all users • Small investments in the OGC process help to reduce technology life cycle risk and cost – minor investments by many OGC members often yields industry action and consensus on standards. When this happens, organizations reduce their reliance on custom solutions and associated maintenance costs Making Location Count… © 2007 Open Geospatial Consortium, Inc. 18
