THIS MONTH'S MESSAGE
By David Arctur
Director, Interoperability Programs
Whenever a large office building is being constructed, it seems like a long
time goes by at first, with very little visible progress. The foundation and
infrastructure are often below ground level and behind a fence, making it even
harder to see progress. But once the walls start to go up, every day brings
dramatic changes.
We seem to have reached the "wall building" stage now, regarding OGC standards
in the geosciences. It was just 2 years ago, after 16 years of work within OGC
on the core standards for mapping and sensor observations, that we first talked
with the World Meteorological Organization (WMO) about letting us help shape
their future standards. At the "First workshop on use of GIS/OGC standards
in meteorology"" OGC and WMO both realized that many members of the meteorology
community were using OGC WMS, WCS, and WFS standards in interesting ways, but
different than we expected, and not all the same, handling some concepts that
were new for us, such as forecast time and mapping of weather variables like
temperature and pressure. The workshop, organized by the UK Met Office, the
European Centre for Mid to Long Range Weather Forecasting (ECMWF), and Météo
France, was a first attempt to determine best practices for using and extending
OGC standards in European meteorology.
Similarly in the hydrology field, the US-based Consortium for the Advancement of
Hydrologic Science (CUAHSI) had been working for 8 years to evolve a service-
oriented architecture for cataloguing time-series observations from the millions
of stream gauges in the US maintained by USGS, EPA, NOAA's National Weather
Service, and various state agencies. As this system was coming online and being
adopted within USGS and NWS, CUAHSI realized that OGC could help ensure global
application of the architecture. They started working with us to adapt their
initial customized SOA to OGC standards, which turned out to be a good fit. But
they realized the need to draw in more hydrology domain scientists, so CUAHSI
sent OGC to the WMO Commission for Hydrology (CHy) meeting in Geneva, just a
couple weeks before the first meteorology workshop, to see what we could
develop.
From the serendipity of these two meetings being co-located with meetings of
the WMO's key domains grew a commitment between OGC and WMO, formalized a year
later, to support each other's standards program through designated experts
chairing the relevant working groups in both organizations. This goes beyond
meteorology and hydrology to include climate, oceanography, and atmospheric
science commissions within WMO. This ensures that WMO retains intellectual
control of the domain sciences of concern to them within OGC, while taking
advantage of OGC's strengths in convening interdisciplinary collaborative
meetings four times a year, around the world.
Steven Ramage and I recently attended the "Third workshop on use of
GIS/OGC standards in meteorology" hosted by the UK Met Office at their
facilities in Exeter, co-sponsored again by ECMWF and Météo France. The
meeting was attended by experts representing national agencies in weather,
climate, aviation, and defence from Europe and now North America. (NOAA will
host the 2011 workshop). This year, OGC members on the European INSPIRE
Thematic Working Group on Atmospheric Conditions and Meteorological Geographic
Features are planning to implement the INSPIRE requirements for a limited part
of the complete information model, through an OGC Interoperability Experiment.
Still another thread of geosciences outreach for OGC is our participation in
the annual conferences of the American Geophysical Union (AGU) in San Francisco
each fall, and the European Geophysical Union (EGU) in Vienna each spring. We
have chaired sessions at these conferences since 2008 within a newly created
domain section of both called Earth and Space Science Informatics (ESSI). At
the AGU meeting just held, we saw that OGC standards and practices are being
included in the core architectures of important new NSF-funded observation
networks and archives, such as DataONE.org and IEDAData.org. We also see new
areas we need to work with, such as provenance automation and integrated
modeling frameworks. As an indication of growing recognition of the role we can
play in fostering interdisciplinary collaborations of domain scientists and
cyber-infrastructure developers, we have been asked to be a sponsor at ESSI's
future meetings and to contribute to its publications. The future for
geosciences in the OGC is bright!
On behalf of everyone on the OGC staff, I thank you for your support in 2010
and wish you all a very happy and successful 2011!

CTO’S REPORT ON NOVEMBER/DECEMBER 2010 TC AND PC MEETING
By Carl Reed
Executive Director, Specification Program, CTO
For the first time ever, the OGC Technical and Planning Committee meetings were
hosted in Australia. Sponsored by CSIRO and hosted at the University of Sydney,
over 120 professionals participated in the meetings. The Australian community
was very well represented and exhibited a continued high interest and commitment
to the OGC and the use of OGC standards. Thirty two different OGC Working Groups
met and worked on revisions to existing OGC standards, discussed requirements
and use cases, tangled with procedural and policy changes, and worked on several
new OGC standards. Further, there were over 50 presentations on the use of OGC
standards. These presentations included updates on the Hydrology
Interoperability Experiments, OGC Web Services Testbed 8.0, deployment of OGC
standards in warning and alerting applications, and ongoing OGC related
standards work in numerous domains, such as Aviation, 3D, Meteorology, and
Hydrology.
Thanks to everyone who made the journey (short and long!) and helped make the
Sydney meetings very successful and productive.
A slide set containing information on the approved motions and informative
announcements can be downloaded from the portal:
Cheers!

PARLEZ-VOUS FRANÇAIS? – OGC'S REGIONAL FORUMS
By Athina Trakas
Director, European Services
Language as well as cultural, political and administrative factors shape our
work, thinking and decisions.
As an international standards body that is addressing requirements and
challenges from various communities related to geospatial and location topics,
the OGC addresses region-specific circumstances to a certain extent within its
membership and work. This is done through cooperation among Consortium members
in a regional and national context and has led to various OGC forum activities
around the world.
Those activities reflect the needs and culture of OGC members' regions or
countries, and they promote dialogue within a single culture, language and/or
political context. But there's no blueprint for all forums. They vary not only
in the above-mentioned aspects, but also in their organisation, the connection
to stakeholder communities and leading players in each country.
The OGC's emphasis on forum activities helps to bridge gaps between various
members. There are currently 7 active forums - all different in languages and
organised differently: the French Forum, the Iberian and Latin-American Forum
(ILAF), the India Forum, the Italian Forum, the Korea Forum, the South-East
European Forum, and the UK & Ireland Forum.
Our European forums activities help the OGC gain stakeholder confidence in
programs like INSPIRE (Infrastructure for Spatial Information in Europe) and
other National Spatial Data Infrastructure programs, and these activities
lead to better cooperation with government bodies such as the European
Commission.
The OGC's international standardization community benefits from regional forums
because they help to make OGC standards truly international. International
standards must accommodate as many national and regional requirements and
priorities as possible. Also, uptake and deployment of international standards
depend on outreach activities consistent with the language, culture, policy
and political environment of many nations and regions. The organisational
structure of the current active forums are quite different. In some cases they
involve simply an email reflector for information and discussions, and in other
cases they involve regular meetings, maintenance of public websites and the
organisation of Interoperability Days. What is common to all of the OGC's
regional forums is that they depend on the leadership and participation of
OGC members in a country or region for their success.
In the next newsletter we will provide a more detailed description of the
various activities in one of the OGC regional forums.

WEBSITE OF THE MONTH: BHUVAN
Bhuvan [http://www.bhuvan.nrsc.gov.in/] (the name is derived from Bhuvana, the
Sanskrit word for Earth) is an initiative of Indian Space Research Organisation
(ISRO), Department of Space, Government of India, to showcase Indian Earth
Observation capabilities from the IRS series of satellites. The images showcased
on Bhuvan are from Multi-sensor, Multi-platform and Multi-temporal domains with
capabilities to overlay thematic information, interpreted from such imagery, as
vector layers.
All the Ministries involved in managing natural resources in the country at
National to local level become part of Bhuvan, as the national imperative
applications are done jointly with them. This one-stop versatile Indian Earth
Observation visualization system can be of vital use for planners, decision
makers, social groups, village communities and individuals. Bhuvan provides a
gateway to explore and discover the virtual Earth in 2-Dimensional,
3-Dimensional space with tremendous possibilities for adding value at the user
end.
Bhuvan enables users to share and overlay maps and geospatial feature data
through services that implement the OGC Web Map Service (WMS) and Web Feature
Service (WFS) interface standards and the OGC KML encoding standard. These
services are hosted by ISRO's National Remote Sensing Centre (NRSC). Bhuvan's
versatile tools support development of interactive applications for
visualization, query and analysis.
The Bhuvan 2D interface is built using OpenLayers - a popular, open source WMS
client. The 2D map browser provides map navigation, map panning, line drawing,
point polygon, overview map, linear and areal measurement, and search. A
downloadable plug-in provides "fly-over" viewing capabilities with interactive
manipulation of view angle, distance, elevation and motion in a 3D landscape.
Bhuvanites (Bhuvan Users) can create and place 3D models, 3D polygons, take
"snapshots", measure distances and perform shadow analyses.
Various services available in Bhuvan, such as land services, weather services,
disaster services and ocean services cater to specific needs of the scientific
community and administrators, supporting their efforts to provide societal
value.

OGC: 2010 THE YEAR IN REVIEW
Below are some highlights of the OGC's 16th year:
* Despite difficult world economic conditions, the OGC continued its year-
over-year membership growth.
* Two additional OGC Interoperability Program Director staff, Nadine Alameh
and Luis Bermudez, were hired to provide highly skilled expertise to IP
initiatives. Both have PhDs in their chosen areas. Lance McKee, a long-
time consultant to OGC, joined the staff as full-time Senior Staff Writer
and Steven Ramage (previously the OGC business representative at
1Spatial) joined to head up marketing and communications.
* Two new membership levels, Associate GovFuture Local Membership and
Associate GovFuture Subnational Membership, were added in November to
increase participation by local, state and provincial organizations. The
GovFuture focus is not standards development, but rather implementation,
business value, "best practice" and virtual forums (teleconferences,
webinars, email lists, access to the OGC Portal etc.).
* A Business Value Committee (a subcommittee of the Planning Committee) was
chartered to help shape the message of value related to participation in
the OGC and the value of implementing OGC standards. The new committee has
a Chair from MobiLaps currently working at NASA, Marge Cole and two Vice
Chairs, Emmanuel Mondon from Erdas in Europe and Kylie Armstrong from CRC-
SI/Landgate in Australia.
* In 2010, the OGC Specification Program witnessed its highest level of
standards activity since OGC's inception. Over 30 Standards Working Groups
were active in 2010. Lifecycle maintenance of existing OGC standards has
become a new priority. The following candidate standards were approved in
2010:
o Abstract Specifications Approved in 2010:
- Linear Referencing
- Observations and Measurements Model
o OGC Standards Approved in 2010:
- Web Coverage Service 2.0
- CS-W ebRIM for EO 1.0
- Web Feature Service 2.0
- Filter Encoding 2.0
- SWE Common 2.0
- Sensor Planning Service 2.0
- SWE Services Model 2.0
- Table Join Service 1.1
- GML Simple Features profile 1.1
* The following candidate standards are scheduled for completion in mid to
late 2011.
o OGC Standards in-progress for approval in 2010 and 2011:
- Moving Object Snapshot (GML)
- SensorML 2.0
- CityGML 2.0
- WMS 2.0
- WPS 2.0
- GML 3.3
- GeoSMS 1.0
- Geosynchronization 1.0
- GeoXACML 1.1
- GML in JP 2000 2.0
- EO Metadata Profile for O&M
- GeoAPI 3.0
- OMXML (Observations and Measurements - XML Schema)
- GeoSPARQL1.0
- cf-NetCDF 1.0
- OWS Context
- Ordering Service 1.0
- PubSub 1.0
- Simple Features 2.0
- WFS Gazetteer application profile
o Two candidate standards in progress are likely to play an important
role in consumer applications and other application domains. The
first is the candidate Open GeoSMS standard, which defines a short
messaging service (SMS) encoding to exchange lightweight location
information between different mobile devices or applications. The
second is the OGC candidate GeoSynchronization Service Standard that
describes an open standard interface to a software service. It
allows data collectors to propose changes to be made to a data
provider's geospatial features (such as data about property lines,
city population, vehicle location, etc.).
* The Interoperability Program completed the following activities in 2010:
o Testbeds: The OGC Web Services Phase 7 (OWS-7) Testbed
successfully. The OWS-8 Testbed planning completed with the release
of a Request for Quotation / Call For Participation on 22 November.
This $1.8M testbed is supported by ten US and European government
and industry sponsors, and will conduct activity threads for
Observation Fusion, Geosynchronization, Aviation, and Cross-
Community Interoperability (data model semantics).
o A major Fusion Standards Study
commissioned by the US National Geospatial-Intelligence Agency generated
key industry and OGC member recommendations on sensor, feature and
decision fusion standards, several of which have been addressed in OWS-7
and OWS-8 testbeds.
o Pilot Initiatives
- The OGC completed phase 3 of the Global Earth Observing System
of Systems (GEOSS) Architecture Implementation Pilot.
- GEOSS, INSPIRE and GMES an Action in Support (GIGAS)
technical and program support to the multi-year European GIGAS
project concluded in June 2010 with the issuance of final
GIGAS architectural recommendations.
- OGC's participation in a European FP7 EO2HEAVEN project
commenced in the latter half of 2010. This multi-year project
involves the OGC and FP7 consortium partners like iGSI
conducting pilot initiatives related to health surveillance
via standards-based Earth Observation and other techniques.
- FAA Special Activity Airspace Information Dissemination Pilot
- will work to further extend the Federal Aviation Authority
(FAA) System Wide Information Management (SWIM) Architecture
to employ OGC web services. This effort builds on previous
testbed activities.
o Interoperability Experiments
- The OGC Hydrology Domain Working Group
is advancing two key Interoperability Experiments for Surface
Water and Ground Water
- The Authentication Interoperability Experiment
is working to test standards-based mechanisms to transfer
authentication between various OGC services.
- The Shibboleth Interoperability Experiment commenced in 2010
to advance best practices for implementing standards on
federated security in transactions involving geospatial data
and services.
o Several new OGC IP initiatives are being formalized:
- Department of Homeland Security Sensor Standards
Recommendation Study 3D Portrayal Interoperability Experiment
- Participation in a proposal to the European Commission
regarding the Future Internet (FP7-2011-ICT-FI).
* A new OGC Standards Fast Track process was developed and implemented in
2010. This new process is in testing through the end of 2010. The Fast
Track process speeds up the overall time taken to approve a candidate
standard and will allow staff to better engage in certain standards
activities in areas such as lightweight standards for the Mass Market
(consumer applications), to benefit Members and the IT community.
* Cooperation continued between the OGC Specification Program and other
standards organizations to ensure that location content and service
instances remain as consistent as possible through the standards stack as
used in other domains. Success continues in OASIS, the IETF, ISO and the
National Emergency Number Association (NENA). For example, a variety of
OGC GML application schemas are part of mandatory standards for use in the
Next Generation 911 program in North America.

TWO MUST-SEE VIDEOS
Professor Steve Liang's GeoCENS (Geospatial Cyberinfrastructure for
Environmental Sensing) group at the University of Calgary (an OGC member)
developed a wonderful short video [http://vimeo.com/14431401] for a recent
workshop in Banff. GeoCENS is an open standard-based virtual globe sensor web
browser for the biogeosciences. You can navigate the virtual globe to your area
of interests, and discover/query sensor readings (both real-time and historical
data). Try it!
A new video,
"Automatic installation and operation of sensors in an IP network,"
from MBARI and SARTI demonstrates how "plug and play" for oceanographic
instruments can be accomplished using standard PUCK and SensorML protocols. More
information and software are available at http://www.mbari.org/pw,
-------------------------------------------------------------------------------
GML APPLICATION SCHEMAS GAINING MOMENTUM
2010 has seen considerable OGC GML Application Schema development activity
[http://www.ogcnetwork.net/node/210], both within OGC and in independent
efforts. A list of GML application schemas has been posted and others are under
development. Several OGC Technical Committee Domain Working Groups - Aviation,
Hydrology, and Meteorology & Oceanography - have formed primarily to develop
GML Application Schemas.
provides the basis for community-specific "Application Schemas" that support
data interoperability within geospatial communities of interest. Such
communities benefit from OGC's unique offering of structure, process, standards
expertise and outreach support. Participation provides national government
agencies with a very cost-effective means of meeting their international
cooperation goals.
In the recent LinkedIn discussion in the GML Group, Ron Lake stated: "GML was
not designed primarily to support file exchange - meaning that it was designed
to enable data feeds of geographic content and transactions. This is borne out
in its use in WFS (transactions/requests) and GeoRSS (GML) in data feeds. Note
that GML is also used as a storage model (see CityGML) and as a basis for
complex data feeds (AIXM)." This is a good description of the versatility and
usefulness of GML.
