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”

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.

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

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

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

OGC’s Approach for Advancing Interoperability
• Interoperability Program (IP) - global,
innovative, hands-on prototyping and testing
program designed to accelerate interface
development and validation, and bring
interoperability to the market
Standards
Setting
Rapid Interface
Development
• Specification Development Program –
Consensus processes similar to other Industry
consortia (World Wide Web Consortium, OMA,
OMG, etc).
• Marketing and Outreach Program – education and
training, encourage take up of OGC specifications,
business development, communications programs
