Hosting Committee and Local Community

Supporting Local Organizations

The Denver LOC has the support of a wide range of local organizations. This is reflected in the number and variety of letters of support we have received from organizations, including: Commercial geospatial companies utilizing and contributing to FOSS like AutoDesk, WeoGeo, and Galdos; User organizations like FRUGOS and Rocky Mountain URISA; Government organizations like the USGS; and major research centers like NSIDC and NOAA NGDC.

United States Government Participation

The United States Government has traditionally been a major supporter of FOSS4G, as well as a significant source of free (gratis and libre) geospatial data. In fact, it was the U.S. Army Construction Engineering Laboratories (CERL) that first developed the open source GRASS GIS. This tradition is carried well into the 21st century with projects like the National Aeronautical and Space Administration's (NASA) WorldWind open source virtual globe. The US Geological Survey (USGS) provides free data access to it's geospatial holdings, adding to the significant US Census TIGER/line free data. Recently, the USGS and NASA announced a return to 100% free data from Landsat starting with the first scene captured in 1972 to today.

The current U.S. Administration, lead by President Barack Obama, has issued an Open Government Initiative and established, a website for sharing spatial and non-spatial datasets. This follow up on their campaign platform: “Making government data available online in universally accessible formats to allow citizens to make use of that data to comment, derive value, and take action in their own communities."

This represents an unprecedented call to action from the highest levels of the US Government to release (free, as in libre) data by implementing open geospatial standards. This effort is dependent on the future of FOSS4G. As such, the Denver LOC anticipates significant participation in a Denver-hosted FOSS4G 2011 by civil servants throughout the US Government.

Local Organizing Committee

The proposed Organizing Committee for a Denver-hosted FOSS4G 2011 would slightly redefine "local." Having seen FOSS4G grow to an international scale, we wish to expand "local" to include not just a city, region, or even a state but the entire continent. Our initial organizing committee is mostly local to the Colorado Front Range but will be expanded to include contributors from throughout North America. We will actively seek out input and direction from FOSS4G contributors in Canada and Latin America as well as Indigenous Nations.

He ran his first GIS project fifteen years ago on proprietary systems and solutions, and is excited to see such progress in the OSGeo arena. David's first "mapping" experiences were when he was a UC forestry student using stereoscopic plotters. WE HAVE CERTAINLY COME A LONG WAY

The Geospatial Open Source Community in Colorado

As a hub of technical innovation, the Front Range features a variety of companies and individuals deeply interested in the application of open source geospatial software. In the Summer of 2006, Sean Gillies and Brian Timoney organized a mailing list to loosely tie users together and christened it "FRUGOS"—Front Range Users of Geospatial Open Source. What has characterized FRUGOS since its inception has been the participation of folks from a broad swath of backgrounds who don't necessarily consider themselves "GIS" people. Indeed, Colorado has a number of organizations catering to traditional GIS constituencies, so in many ways it has been quite edifying to bring out in the open the latent interest in alternative approaches with geospatial open source.

Among the events FRUGOS has organized has been an UnConference hosted by Tom Churchill (of Earthscape renown) in Boulder that drew about 25 enthusiasts, including folks such as Scott Davis, Peter Batty, Charlie Savage, et al. In addition, we had an after-hours MapServer/PostGIS workshop hosted by Bruce Rindahl in Denver that drew an overflow crowd of at 35 people, remarkable for the fact that they were more "mainstream" GIS users than "hackers". Last winter saw FRUGOS-apalooza: four events, four nights, four bars in Denver, Ft. Collins, Boulder, and Colorado Springs. Just as important as the 20-25 attendees for each stop was the fact that by getting the word out via the primary GIS mailing lists (maintained by GIS Colorado) as well as other non-GIS open source mailing lists, the "tour" created an awareness of FRUGOS that far exceeded those who attended.

The exposure of open source solutions at the GITA-sponsored GIS In the Rockies conference in recent years. From showing the role of MapServer in the City of Denver's GIS Department to Tim Beerman of CH2M-Hill demonstrating live feature editing in Google Earth using Feature Server and PostGIS, this too has been a venue for the traditional "base" of the GIS Community to exposed to real-people-doing-real-things with open source.

In short, through the work of FRUGOS, we not only are effectively providing a forum for current users of geospatial software in the area, but are providing opportunities for long-time users of proprietary GIS packages to learn more and see its everyday uses up close. The implications for hosting the FOSS4G 2011 conference are clear: a large community of GIS users who are aware of the role of open source software in their field as well as a track record of well-attended FRUGOS events geared to both the hacker specialist and the manager/generalist.

Use of Free and Open Source Software in Denver/Boulder Research Centers

Open Source software is used extensively in regional research institutions such as the National Snow and Ice Data Center (NSIDC), NOAA's National Geophysical Data Center (NGDC), Unidata, and university departments. As an example, NSIDC stores ever-increasing amounts of data and metadata in PostGIS databases, which in-turn drive interfaces based on MapServer, GeoServer, and OpenLayers. Datasets are subsetted on-the-fly using GDAL. NSIDC's drive to use Free and Open Source software is a combination of low cost, high performance, flexibility, and the ability to share solutions and IT infrastructure with collaborating outside institutions. They have found that FOSS geospatial software has good functionality and high performance that easily meet their system requirements.

Support is plentiful via online documentation and mailing lists, and there have been cases where reported bugs have been fixed in a matter of hours. NGDC uses both open-source and commercial software to accomplish their mission and depends on Open Geospatial Consortium (OGC) standards. While in some case this involves using only open-source software, NGDC has also been very successful in integrating open-source and commercial software to develop powerful solutions. Unidata, part of the University Corporation for Atmospheric Research (UCAR), is dedicated to providing tools and infrastructure to support earth and atmospheric sciences. They are the developers of the netCDF data access libraries, the IDV visualization tool, and heavily involved in the development of the OGC WCS standards. In short, the research centers in the Denver/Boulder region benefit greatly from many Free and Open Source geospatial software applications, and are giving back to these communities through sharing expertise and bug reporting.

Denver and OSGeo

A transparent working relationship and open collaboration with OSGeo are integral to a successful FOSS4G 2011. The Denver LOC will work with the OSGeo Board of Directors and Conference Committees concerning all key FOSS4G developments and decisions. Communication will include formal quarterly reports on all committee activities, as well as a final report at the conclusion of the event. All conference materials will be provided in original form and without license.

If Denver is chosen to host FOSS4G 2011, the LOC requests that a member of the OSGeo Board of Directors joins the LOC as a liaison to help ensure OSGeo’s vision and strategy remain at the forefront of all planning activities.

As FOSS4G continues to evolve and grow, the Denver LOC also understands that learning from and building upon past events is extremely important to broadening the scope of this event. The committee will continue to consult Lessons Learned from previous FOSS4G and other resources on the OSGeo wiki. All conference information and additional resources will also be added to the wiki if Denver is chosen to host the 2011 event.
