PRESIDENT'S MESSAGE: 2007 KENNETH D. GARDELS AWARD
At the July OGC meetings in Paris, Clemens Portele of interactive instruments GmbH was awarded the OGC's ninth Kenneth D. Gardels Award.
Clemens has been deeply involved in a range of important OGC programs. The success of OGC's cooperative endeavor with ISO owes much to Clemens' diplomacy, patience and persistence. His leadership role in the INSPIRE (Infrastructure for Spatial InfoRmation in Europe) Data Specifications Drafting Team contributes to a process that influences the progress of European policy with respect to OGC standards. He has also provided important support to a range of OGC documents including the GML application schema for use by OASIS, a GML version of the Aeronautical Information Exchange Model (AIXM), and the GML Simple Features Profile, to name a few. I ask that you visit the OGC website to read his award citation and the citations of previous award winners at http://www.opengeospatial.org/ogc/awards
The occasion of Clemens' award merits some words about Kenn Gardels and the mission of our Consortium.
The Gardels Award was conceived to memorialize the spirit of Kenneth Gardels, a founding member and director of the OGC. Kenn was a man who dreamt of making the world a better place through open communication and the use of information technology to improve the quality of human life. The OGC Board selects the annual award recipient from nominations provided by a committee comprised of previous Gardels awardees.
Kenn coined the phrase "Open GIS". He was active in popularizing the open source GIS "GRASS" and was a key figure in the early Internet community of people who used and developed that software. Kenn was well known in the field of GIS and was involved over the years in many programs related to GIS and the environment. He is remembered for his principles, courage, and humility, and for his accomplishments in promoting spatial technologies as tools for preserving the environment and serving human needs.
Kenn embraced the concept of "Think globally, act locally." This phrase originated with scientist René Dubos at the United Nations Conference on the Human Environment in 1972. The phrase grows ever more meaningful with humanity's growing concerns about climate change, population growth, pollution, energy constraints and the "flattening" of the world community. "Think globally, act locally" is particularly meaningful for the geospatial community, because our technologies help people rationalize seemingly broad and at times intangible issues into a local context, and because the environmental themes Gardels and Dubos cared about are so obviously tied to geospatial features and phenomena.
I am, as Kenn would be, grateful to each of the people who have received the Gardels award. I am grateful for their extraordinary efforts and their leadership in our unique community, and for helping to advance the interoperability mission of the Consortium. Clemens has earned the appreciation of the others who participate in the OGC, but he would be the first to point out that this is a collaborative effort in which we are all helping each other achieve common goals. For me, it is truly an honor to be part of this community.

NEWS AND OPINION FROM THE BLOGOSPHERE
Below are some of the discussions of OGC specifications in the blogosphere since the last edition of this newsletter:
8 June: In "It's About Place (Part 2)" -- contributed to Sramana Mitra's blog by Cal McElroy -- he discusses some of the history of location technology, and toward the end of the article he notes, "While OGC set out to liberate geographic data from proprietary GIS and mapping systems, ultimately they sparked a revolution that will enable location intelligence in any application or web service."
On April 18, blogger Steve Lombardi at Virtual Earth spelled out the promise of GeoRSS: "a standard way to exchange map information with the potential to impact geo technologies the way rss/atom have changed the way we deal with news and other information."
17 April: Jelle Hielkema at the UNSDI HUCO blog shared the announcement reported by Jeroen Ticheler of FAO NRCE, that they have implemented the Open Geospatial Consortium Catalog Services for the Web (OGC-CSW) specification. "As a result of the project, GeoNetwork opensource is the so-called Reference Implementation of the CSW specification for the OGC."
4 April Sebastian Good, who blogs at "It is what it is" asks what REST means for GIS, and goes on to comment that "... The Open Geospatial Consortium (OGC) guys have had a good amount of luck getting some useful standards into widespread use."
30 March. Chad in "The Earth Is Square" highlighted the release by NGA of "Geospatial Intelligence Standards: Enabling a Common Vision". He pointed out that it endorses the Open Geospatial Consortium (OGC) Spatial Data Infrastructure (SDI) 1.0 baseline. The post generated 8 comments.
WEBSITE OF THE MONTH
The OOSTethys website describes developments in ocean-observing systems, with a focus on progress toward a system-of-ocean-observing-systems. OOSTethys provides a community-developed set of software tools that implement OGC specifications. It also offers guidance documents ("cookbooks") to help data providers get started using standards-based data-exchange capabilities.
- Sensor network feeds observations to DATA PROVIDER (an OOS system such as GoMOOS)
- Data Provider installs SOS software and registers URL with OOSTethys REGISTRY (or catalog) (for this project, the catalog is at UAH)
- Data Provider sensor observations become discoverable to the OOSTethys DATA AGGREGATOR (OpenIOOS)
- OOSTethys CLIENT runs GetProviders and GetCapabilities processes every hour to generate current map of active data providers and the observations that are available.
- Map is generated and displayed on DATA ANALYZER and VIEWER (OpenIOOS.org)
- End user clicks point on map at http://www.openioos.org, GetObservation process is kicked off and current observation is returned to user.
Also noteworthy are details of OCEANS IE and information on how to participate. OOSTethys participants initiated an OGC Interoperability Experiment in December 2006 to engage data managers and scientists in the Ocean-Observing community to advance their understanding and application of various OGC specifications, solidify demonstrations for Ocean Science application areas, harden software implementations, and produce candidate OGC Best Practices documents that can be used to inform the broader ocean-observing community.
In April, Microsoft launched a new version of Live Maps with GeoRSS publishing. Points, lines and polygons are supported. The functionality is illustrated at "My Bike Trails," which features rides around Seattle.
The National Weather Service provides experimental web feature service (WFS) access to the National Digital Forecast Database. Comments and feedback are requested and will be accepted through 31 October 2007. For more information, see the announcement made by NOAA's Office of Climate, Water and Weather Services. See also the National Digital Forecast Database (NDFD) Experimental Web Feature Service (WFS) web page.

OGC IN THE NEWS
- OGC in the Press
In the July issue of GIM International, Dale Lutz's essay "Uniting an Industry" identifies several ways in which his company, Safe Software, benefits from the interoperability enabled by OGC standards. His closing paragraph conveys his belief that the benefits extend far beyond his company: "The geospatial community owes much to the OGC for championing the vision of data interoperability and providing a framework for the realisation of this vision."
The July issue of Geospatial Today includes an article by Carey Mann, "Integrated GIS is the future," in which he notes a trend toward "...greater leverage of interoperability technologies (such as OGC standards like WMS and WFS)."
The same issue also includes a brief article, "GML - the key enabler," in which Sam Bacharach provides a look at the history and status of the OpenGIS® Geography Markup LanguageTM (GMLTM).
In July, GIM International contributing editor Christiaan Lemmen introduced the fourth product survey on "Spatial Data Management in Geo-databases" by reflecting on progress since the first survey in 2002. At that time, he observed that spatial-data management was traditionally supported within GIS environments; integrating spatial data with other datasets had to be explicitly organized with the aid of complementary architectures. In comparison, "Five years on, a set of mature geo-databases is available on the market, .... Thanks to OGC, developments have been rapid."
A June article in Geospatial Solutions, GeoSite Simplifies Site Management, noted that "GeoSite relies on Open GIS Consortium (OGC) specifications, such as the Web Map Service (WMS), to dynamically query GIS data and return the result in a format that may be displayed in Google Earth."
GeoTEC Event 2007 in May featured a full-day workshop on OGC Web Services, and a number of presentations about work involving OGC standards. For example, the following abstracts can be viewed online:
- Using 3-D Open Web Services for a Better Collaborative Response to Disaster Management (page 3)
- National Forest Information System: We're More than Just Maps (page 3)
- The Alberta Web Mapping Services Prototype Project (page 1)
- Extending the Web Map Service to Handheld Devices (page 1)
- Management and Web Distribution of Very Large Volume (100TB) of Digital Image Data (page 3)
The March 2007 issue of "BuildingSMART News" noted (page 2) the organization's collaboration with OGC, including input to OWS-4. The group is particularly interested in CityGML and the interfaces to it.
