This Blur's For You

Since 9/11, security has become the watchword of the nation, though the initial hysteria has begun to abate somewhat. However, one of the ongoing casualties of the crusade for hyper-security has been access to once-public information. Maps and mappable information have been primary targets. The blurred image comes from Google Maps, and is an apparent attempt to hide the Salem Power Plant, a coal-fired power plant in Salem, Massachusetts. This is not unusual. In fact, one Wikipedia entry has managed to create a lengthy list of sites throughout the world that appear to have been censored by Google Maps - blurred or conspicuously missing imagery (see "Satellite map images with missing or unclear data"). Google has been largely silent about this practice in the U.S., though some governments (e.g., India) have been very public about asking Google to blur images of sensitive sites. At least one local politician in New York is also calling on Google to blur aerial imagery of sensitive military and government sites. There is also evidence that Google may be altering aerial imagery of sensitive commercial sites, such as areas where genetically modified crops are grown (see "What Google Won't Map," Gridskipper).

It's difficult if not impossible to know what kinds of geographic data have been censored or even deemed censor-worthy, either by government or other institutions. In July 2006, the federal Department of Homeland Security (DHS) released its National Infrastructure Protection Plan (NIPP),which provides the framework for how all levels of government and the private sector will manage the protection of the nation's critical infrastructure and key resources. An important part of this framework is the designation of what actually constitutes "critical infrastructure." In fact, it wasn't long before DHS came under withering criticism by its own Office of Inspector General, as well as Congress, for the NIPP's overly expansive definition of "critical infrastructure." As Senator Barbara Boxer of California put it, "I would love to provide protection for every activity in America, but the reality is that we need to set priorities" (see "DHS Officials Quarrel Over Internal Report," RCR Wireless News 07/24/2006).

The lack of a coherent national policy has not stopped government agencies from implementing their own ad hoc procedures. A recent report by NPR featured the struggle between a computer consultant and the state of Connecticut over access to GIS maps of water and sewer systems in the towns of Greenwich and Stamford (see "Security Officials Seek to Block Some Online Maps" NPR 10/8/ 2007). Connecticut's Freedom of Information Commission ruled that such data were too sensitive, and that the towns could only release maps without sewer and water systems, fire hydrants and man holes. Here in the Commonwealth of Massachusetts, the state's GIS dissemination agency MassGIS has implemented minimal security protocol around certain GIS data sets. Users wanting to download GIS data of large hazardous waste generators must first fill out a request, which includes detailed contact information, before being sent a link to enable download of the data.

MassGIS's approach is not too different from policies set in place by the Federal Energy Regulatory Commission (FERC) regarding Critical Energy Infrastructure Information (CEII), which FERC defines as "existing and proposed systems and assets, whether physical or virtual, the incapacity or destruction of which would negatively affect security, economic security, public health or safety, or any combination of those matters." That's about as specific as they get (see "FERC Tries to Strike a Fine Balance," Electric Utility Week 11/13/2006). Moreover, FERC allows utilities - whether private or publicly owned - to define for themselves what should be classified as CEII when those entities submit required documentation and information. This loose discretion, and the overzealous application of the CEII designation, actually worked against FERC and the energy industry in at least one case. California officials recently nixed a $700 million liquefied natural gas terminal proposed by Sound Energy Solutions (SES) because neither FERC nor SES were forthcoming with all of the information needed to complete the final Environmental Impact Report (see "Long Beach LNG terminal dead in water after officials end environmental review," Gas Market Report 01/26/2007).

It's worth remembering that there is social value, including safety and security, in public access to information about critical infrastructure and even hazardous or dangerous facilities. Some of the most important laws and traditions around public access in the U.S. were founded specifically on concerns about safety and security. In December 1984, a pesticide plant in Bhopal, India blew up, releasing a deadly cloud of methyl isocyanate gas that killed over 20,000 people in the surrounding community, and permanently maimed up to 100,000 others. It was (and still is) the worst industrial disaster in history. A host of factors were involved in the making of this catastrophe, but one of them was the complete ignorance of anyone outside of the plant about what was going on inside the plant (including local officials). A sister facility in Institute, West Virginia experienced a comparatively minor incident at about the same time (sending 134 people to the hospital), but the horror of Bhopal had already set the world on edge. In the U.S., the federal government and the public were still reeling from the drama at Love Canal and the discovery of previously uncounted and hidden sources of hazardous chemicals throughout the country. As a result, Congress passed the Emergency Planning and Community Right to Know Act (EPCRA) in 1986, which established requirements for emergency planning and reporting on hazardous and toxic chemicals. This legislation required facilities storing or handling potentially hazardous materials to report this information to State Emergency Response Commissions, Local Emergency Planning Committees, and local fire departments. In addition, it created a toxic release inventory (TRI) system that enabled the the tracking and monitoring of chemicals and facilities throughout the country. The TRI and other EPCRA provisions have been some of the most important tools for researchers as well as public health and safety officials. An enormous volume of environmental health and safety research and planning has relied on regular access to mappable TRI data. More importantly, this legislation recognized and institutionalized the right of communities and the public to have access to information about activities with health and safety implications.

On the 20th anniversary of the Bhopal tragedy in 2004, two EPA officials reflected on the evolution of incident prevention and response at chemical facilities over the last two decades. They argued that Bhopal and 9/11 were the transformative events, both of which highlighted the issue of safety and security, but with diametrically opposed results (see "The Post-Bhopal and Post-9/11 Transformations in Chemical Emergency Prevention and Response Policy in the United States"). It is an odd twist of circumstances that public disclosure, once touted as the mechanism to promote safety and security, could so quickly be relabeled as a threat to security.

To help search for [NAME/ENTITY] click here ...

In 1997, the folks at SETI (Search for Extra Terrestrial Intelligence) announced the launch of the SETI@home project - an effort to engage the public, literally, in the search for technically advanced alien life. By simply downloading an attractive screen saver, individuals could donate the spare computational power of their idle computers, creating a distributed, virtual supercomputer, reducing the money and time spent by scientists, and increasing the chances of detecting an extraterrestrial radio transmission. To date, some 6 million individuals from almost every country on the planet have participated, creating in effect the largest coordinated computational effort in human history. SETI@home has spawned successful imitations on the search for cures for cancer (folding@home), modeling of climate change (climateprediction.net), and others (see "Searching for E.T. and the Cure for Cancer" Planetary Society May/June 2007).

In 2007, a similar effort is unfolding. On Monday, September 3, 2007, wealthy adventurer Steve Fossett was reported missing after failing to return to an airstrip at a southern Nevada ranch while piloting a light aircraft. He was looking for a dry lake bed where he could attempt to break the world land speed record. You might know Mr. Fossett from his other high profile stunts: first person to fly solo nonstop around the world in either a plane or a balloon, swimming across the English Channel, running marathons and climbing the highest peaks on six continents. As Nevada authorities and search and rescue teams mobilized, Fossett's billionaire friend, Richard Branson, asked another friend at Google if it was possible to use the imagery of Google Earth to search for the missing aviator. Many people were surprised to learn (interesting in itself) that Google Earth's planetary imagery is not 'real-time' and that many images may be 3 or more years out of date. Moreover, Google does not collect the imagery itself, but rather purchases it from a variety of other sources. However, at Branson's request, Google turned around and shelled out at least $100,000 to purchase up-to-the-minute imagery of the Nevada desert from two companies (GeoEye and DigitalGlobe) that maintain commercial satellites that acquire high resolution imagery of Earth on a daily basis. But it didn't stop there. Google passed the imagery to Amazon.com, whose online tool Mechanical Turk allows thousands of people to share the job of combing through the aerial and satellite imagery in search of Steve Fossett. When you arrive at Amazon.com's dedicated Steve Fossett search site, you are greeted with the message "To help search for Steve Fossett click here," and presented with sample images and instructions on how to engage in the search. According to Steve Cohen, coordinator of Amazon's search site, "thousands of people" have signed up to participate ("Internet Users Join Search for Steve Fossett" NPR 09/12/07; "With Web's Help, the World Joins Search for Fossett" Washington Post 09/14/07).

The editors at Directions Magazine, a geospatial industry news source, examined the Steve Fossett search as a "teachable moment" in a recent podcast - focusing on the education of the wider public on the variety of technologies employed in this endeavor (from aerial and satellite pictures to hyperspectral imagery). As they describe it, this effort represents a convergence of technologies - Internet and geospatial. This is indeed significant - there is no bigger or more important trend in geospatial technology than its co-evolution with the Internet. However, I would argue that there is more to these phenomena than simply technological evolution. We are increasingly seeing the potential of combining massively distributed resources (i.e., Internet and computers and open source software) with a widespread willingness of both expert and non-experts to volunteer their time and energy and resources for the greater good (however that might be defined). Before Steve Fossett, there was Hurricane Katrina. In the chaotic aftermath of the August 2005 hurricane events that devastated the Gulf Coast (don't forget Hurricanes Rita and Wilma), a general call went out for GIS experts to bring their laptops to the disaster zone to aid in search and rescue and recovery. So many answered the call that most had to be thanked and turned away. As it became evident that federal and state government efforts would fall short in aiding individuals, faculty and students at Louisiana State University's Geography department took the initiative. At the same time, non-experts stepped up and used existing free tools, such as Google Maps, to create online resources to help post timely information about specific locations affected by the storm - news by people in the area for people in the area (see http://www.scipionus.com/).

In December, Michael Goodchild - the GIS deity who resides at UC Santa Barbara - will convene a specialist meeting of hand picked experts to discuss what Goodchild calls "volunteered sources" - "a flood of new web services and other digital sources ... that can potentially provide rich, abundant, and timely flows of geographic and geo-referenced information." Goodchild suggests a number of important questions, including the motivation of individuals to provide georeferenced data publicly and the potential of combining advanced Internet technology with human brain power. It is likely that the experts will be most fascinated with the technological implications, but I think it is equally important to recognize the social significance of so many people's readiness to volunteer their time and resources, as well as the power of combining technology with collective will.

As of this posting, the search for Steve Fossett has led to the discovery of 8 previously undiscovered planes that have crashed in the area over the years, but not the principal target himself. We can only hope that the search for extraterrestrial life will have such collateral success.
