The term 'imageability' was coined by urban theorist Kevin Lynch in the late 1950s, just as Urban Design as a profession was taking shape. In the context of cities and landscapes, the term refers to what many call 'place legibility', or rather "the ease with which people understand the layout of a place." Lynch's ideas were developed in his classic work, Image of the City (MIT). According to Lynch, people develop mental maps of the city and these maps affect how individuals navigate and explore their region. He viewed the city as a network of paths, districts, edges, nodes, and landmarks. I argue that Lynch borrowed this language directly from the then-new field of Network Studies which was in great part incubated at MIT, also. He added to this vocabulary the term 'landmark'. In a future post I hope to discuss how Lynch's addition of 'landmark' could be reflexively applied back on to Network Studies. I also want to extend the notion of imageability to organizations and institutions. But for now, back to the city.

In 1954 MIT Professor Kevin Lynch began studying city form in a five year project funded by The Rockefeller Foundation. The study was done under the direction of Lynch and Professor Gyorgy Kepes at the Massachusetts Institute of Technology Center for Urban and Regional Studies. Their research findings were the foundation of Lynch's theories on city planning discussed in his seminal work The Image of the City. (MIT Library)



The historical discussion about Earth's cities and their interconnections has traditionally utilized two terms. Global City. And World City. As defined on Wikipedia, a global city is a critical node in the global economic system. Not a very precise definition. Maybe some folks who'll be attending the 4th Annual Toronto Forum for Global Cities will be able to provide a better definition. Saskia Sassen is said to have coined the term. She talked about the concept with Foreign Policy just recently. This article comes just weeks after FP's release of their 2010 Index and a whole issue dedicated to cities. Personally, I think Parag Khanna's "Beyond City Limits" article was the standout. As Parag's sub-title reads: the age of nations is over. the age of cities has begun. If we go back a few years, to 2007, we can revisit Tate's awesome exhibition, Global Cities. To Torontonians and students of the Canadian situation, the recently released Toronto as a Global City: Scorecard on Prosperity - 2010 will be of great interest. Theorizing and understanding the city in its cultural, artistic permutations is essential. Too many numbers make for bad meaning. That's why books like Global Cities: Cinema, Architecture, and Urbanism in a Digital Age are a must read every now and then. Not that long ago, University of Toronto's Cities Centre initiated a "Global Cities Indicator Facility" for storing and sharing data about Earth's great cities. The Toronto Star covered this amazing resource in June.
"Eric Fischer has been having a good bit of fun with maps lately. In his latest, he animates movements of the San Francisco MUNI (that's their bus system) over the month of June 2010. Each second of in the video represents about an hour in real life."
The definition is pretty loose if you're just jumping into the mix. The emergent, increasingly dominant vision of an Open City references data and information policy, modes of informing and consulting the public, approaches to IT and governance. But a few other types of Open exist, potentially causing confusion. When examined in a comprehensive light, each has something to offer the larger, expansive definition. Transformative IT practices are at the heart of most of these visions, but in almost every case IT only portends larger, more engaging practices on behalf of City Hall and leading civic institutions. What exactly is an Open City?
Policy’s Role in Shaping New Media
As Internet-based technologies are increasingly used for municipal management, are cities close to developing a set of best practices that could be considered as a consistent policy for cities?
The Dashboard and Diagnostic City
What new diagnostic tools are being used to assess a city’s sustainability and functionality?
Social Media and the Limits of Civic Engagement
What are the difficulties that cities encounter when they try to use social media to engage the public?
New School: Teaching an Interdisciplinary Science
The complexity of a 21st-century city requires interdisciplinary thinking not commonly found in traditional universities. How are universities teaching interdepartmental collaboration among urban planning, technology, computer science and engineering departments?
City as Subject
The panel will discuss the increased number of media outlets covering the city as a topic. Are these different voices adding to the texture of the discussion or cannibalizing their audiences?
What Gaming Can Teach Us about Cities
A selection of online games that encourage interaction with and an understanding of cities through play.
Technology for Social Equity
How can technology be used to increase economic and social equity in cities?
Foreign Perspectives
The last panel conversation will look abroad for best practices in terms of opening data, growing a digital economy and using data-driven policies that can be integrated in the US.
This view of the city recognizes the common element of technology in civic renewal. It also relies heavily on systems thinking. For a long-time open was known through synonyms such as free, and referred to a place where business can be done without problems or barriers. Enterprise and industry, welcome. A recent essay on China's cities is a good example of this use of open. This 'cities' are not marked by sufficient culture, per se, but rather by sanction and incorporation. These cities are special economic zones, as another Chinese resource demonstrates.
It is important to narrowly define a subject so that it can be strengthened and built up. Such is the work of many Canadians. After concentrated innovation, the Open City concepts can then be asked to carry heavier, more broadly ideological burdens, e.g. how do we speak of the city as a whole to its residents, not only to its proponents and advocates? How can the concept of an Open City connect with all residents? What would that take, theoretically speaking?
An older, more chilling definition refers to war-time conflict. An open city is one that has been abandoned by a country's military. The reasons for doing so can vary widely, but in each case the city is said to be an "Open City," open to occupation by would-be opposing, encroaching forces.
Sometimes it's easiest to know a thing by contrasting it with another. In 2005, Richard Sennet said the Open City is the opposite of the Brittle City.
Many definitions of the open city remain. In the end, they won't all mash together. But many will. With all these crossed wires, a graphic may be what's needed. In the meanwhile, I highly recommend reading Sennett's Open City essay. After you've taken in his three main points, try poking around the Urban Age series website, for which Sennett's essay was authored. Very interesting stuff.

"Any city-dweller knows that most neighborhoods don't have stark boundaries. Yet on maps, neighborhoods are almost always drawn as perfectly bounded areas, miniature territorial states of ethnicity or class. This is especially true for Chicago, where the delimitation of Chicago's official “community areas” in the 1920s was one of the hallmarks of the famous Chicago School of urban sociology. And maps showing perfectly homogeneous neighborhoods are still published today, in both popular and academic contexts alike."
This is a simplified systems view of an emerging e-government system where many if not all services are characterized by a digital portal or contact point. How does someone approach these services? How do we prepare people, including children? How can we begin to bring about constancy amidst all this service-delivery upheaval?
When we discuss how something comes to be, we always talk about pre-conditions. This seems unnecessary. We can just as easily speak about the conditions of something. Yes, 'conditions' does imply some aspect of how a thing presently is ("You visited there, right? So, how are the conditions?"), but for the most part refers to the ways things were during a nascent opportunity. Until recently, Open Government could be described as such. That is, from within the moment of experimentation, publishing, conferences, directives, and so on, a fever persisted. "How can we shift from solving problems to creating the (pre-)conditions for solutions to emerge?" Many solutions will be guided by government organizations but not all. In the pockets and at the periphery, civil society and philanthropy double-team. They create solutions to problems, or put differently, essential connections between essential things are made. But inside public organizations, the right technical infrastructure is needed. The narrative of Open Government nearly gets drawn in to a classic battle, wherein a few groups capable of installing and monitoring 'the new large systems' become the better bidders de facto. It is a narrative that deals heavily in technological infrastructure and is therefore prone to growing oligarchic interests, unlike say the managerial musings of Peter Drucker who looks to the gaps between people.
“Citizenship in and through the social sector is not a panacea for the ills of post-capitalist society and post-capitalist polity, but it may be a prerequisite for tackling these ills,” Drucker wrote. “It restores the civic responsibility that is the mark of citizenship, and the civic pride that is the mark of community.”
