The files contain closed polyline layers for buildings, streets, highways, city limits, and geographical data--all ready for use in CAD programs like Autocad, Rhino, BricsCad and SketchUp.
The importance of public spaces in urban life is an issue that has been apparent since ancient Greece and is still with us today. Opportunities to meet and exchange ideas in these spaces are able to influence how the inhabitants participate in the development of their city, and occur in greater instances when public spaces are accessible to everyone.
However, in modern societies, the strategic role of these spaces has been limited. According to The City Fix, a blog on sustainable urban planning, one of the main reasons for this is the overabundance of automobiles. In fact, according to one study by the Brazilian Institute for Energy and the Environment, 70% of public spaces in urban centers are taken up by roadways and other spaces for cars, while car owners make up only around 20 to 40 percent of the city’s population.
How can public spaces be recovered to promote urban life? We discuss three important factors below.
Frank Lloyd Wright once described cities as both ‘our glory and our menace’. With more than half of the world’s population now living in cities, architects are becoming increasingly interested in their origins. Many fields of historical, geographical, and spatial research are devoted to exploring the evolution of cities, revealing a set of similarities across the globe. In a recent video, Wendover Productions described a common set of characteristics linking some of our largest cities, six of which we have outlined below.
Taking the six factors below into account, where is the perfect ‘world city’? Watch the video after the break:
The John S. and James L. Knight Foundation has announced the names of the 144 finalists in the 2017 edition of the Knight Cities Challenge, a nationwide call for innovative ideas aimed at transforming the organizations’ 26 member communities into more vibrant places to live and work. Open to innovators and designers from any field, the challenge requested submissions that responded to a simple prompt: What’s your best idea to make cities more successful?
Pedestrians, the most vulnerable users of road space, will now be more visible to drivers in the Netherlands with the inauguration of a new luminous pedestrian crossing this past November in Brummen, west of Amsterdam.
Designed by the Dutch firm Lighted Zebra Crossing, and installed free of charge for the municipality, this crossing makes pedestrians more visible at night or during bad weather. Each of the lines has two plates of lights that at night remain illuminated at all times and not only when there are people on them.
The latest publication of the National Association of City Transportation Officials, NACTO, is the "Transit Street Design Guide" in which tips and proposals are presented on how to improve streets through urban design.
The ideas are centered on prioritizing sustainable mobility so that both the member cities of the organization and those that have access to this document can improve their practices in relation to public spaces, mobility, and transportation.
Over the last few years, the way Americans move around has changed remarkably, especially among young people. Previously the automobile was people’s preferred, if not the only, option. Now they are choosing to walk, bike, or use public transport according to recent studies.
This difference in preferred transportation methods has generated many benefits not only for residents but also for cities, in both economic and social terms.
Building a highway in a city is often thought of as a solution to traffic congestion. However, the induced demand theory has shown that when drivers have more routes, they choose to continue using this medium instead of using public transport or a bicycle, and as a result, congestion doesn’t decrease.
As a result, some cities have chosen to remove spaces designated for cars and turn what was once a highway into urban parks and less congested streets.
Here we have six examples, some have already been completed, while a few are still under construction. To the surprise of some, most of the projects are in the US, which reflects that American designers are looking into further studying European transport policies.
Buenos Aires' contemporary urban landscape as we know it today provides a tempered mix of historical and recent construction projects. As one of the most beautiful cities in South America, it's wide boulevards and grand buildings, based on European models, have morphed to embrace the needs of a modern metropolis.
These images show just how profoundly time affects our cities (and how centuries-old foliage can powerfully transform spatial perception).

This article was originally published in Metropolis Magazine as "When It Comes to Sustainability, We're Ranking Our Cities Wrong."
A recent article published in Nature makes a bold claim: we're analyzing our cities completely wrong. Professors David Wachsmuth, Aldana Cohen, and Hillary Angelo argue that, for too long, we have defined sustainability too narrowly, only looking at environmental impact on a neighborhood or city scale rather than a regional or global scale. As a result, we have measured our cities in ways that are inherently biased towards wealthy cities, and completely ignored the negative impacts our so-called "sustainable," post-industrial cities have on the rest of the world.Metropolis editor Vanessa Quirk spoke with Professor Wachsmuth to learn more about the unintended knock-on effects of going "green," the importance of consumption-based carbon counting, and why policy-makers should be more attentive to the effects of "environmental gentrification."
From the Cradle of Civilization in ancient Mesopotamia to the modern urban explosion in China, cities are among the most obvious and dramatic evidence of human existence. In a recent paper published in Scientific Data, a team led by Yale University researcher Meredith Reba mapped the emergence of cities between 3,700 BC and 2,000 AD based on when their populations were first recorded in historical accounts.
Taking the data from this study, Max Galka of Metrocosm has produced this fascinating animation showing the history of cities worldwide. "Most datasets available go back only a few years or decades at most. This is the first one I've seen that covers 6 millennia," Galka told CityLab. "I'm a big fan of history, so after reading the study, I thought it would be interesting to visualize the data and see if it offers some perspective." The steady flow of time may seem a little slow at first, but stick with it through the early BC years and the shifts in urban development start to get intriguing. And—spoiler alert—buckle up as you approach the 20th century.
Have you ever wondered which are humanity's oldest cities? Matador Network has compiled a list of the world's ancient metropolises, and perhaps unsurprisingly, nearly all of them are within or adjacent to the Fertile Crescent, a moon-shaped region running from the Persian Gulf through what is today the south of Iraq, Syria, Lebanon, Jordan, Israel, and the Nile River Delta in Egypt. With settings that range from hamlets on the road less traveled, like Susa, Iran, and Sidon, Lebanon, to cities that hold international renown as trade and migratory crossroads, like Beirut and Damascus, these places share an ability to endure through the highs and lows of fortune and conflict. This factor of longevity is all the more remarkable considering that the youngest locales date from 3,000 BC and others extend back another 6,000 years.

Many technological advancements have changed the way we design in the past 150 years, but perhaps none has had a greater impact than the invention of the passenger elevator. Prior to Elisha Otis’ design for the elevator safety brake in 1853, buildings rarely reached 7 stories. Since then, buildings have only been growing taller and taller. In 2009, the world’s tallest building, the Burj Khalifa, maxed out at 163 floors (serviced by Otis elevators). Though a century and half separates those milestones, in that time elevator technology has actually changed relatively little - until recently.

Can architects have a truly active role in pressing social problems? Malkit Shoshan, the curator of the Dutch Pavilion at the 2016 Venice Biennale, thinks so. Her career is evidence of this: advocating for the incorporation of a fourth 'D' in the criteria of the UN (Defence, Diplomacy and Development) in its peacekeeping missions around the world, Shoshan has sat at the same table as military engineers and policy makers to analyze the urban impact peacekeepers have left around the world.
For the Dutch Pavilion, Shoshan has focused on the case of the joint mission of the Netherlands and the UN in Gao (Mali). In 2012, Gao was declared capital of the Independent State of Azawad, a nation not recognized by the international authorities, following Mali's Tuareg rebellion. "Although [these peacekeeping missions] occupy large plots of land in hundreds of different cities around the world, it is rarely discussed or addressed by our profession," says Soshan in the following interview.
We spoke with the curator of the Dutch pavilion after her recent visit to Mali to discuss the principles of the Netherlands in the next Venice Biennale; the impact of military drones in public spaces and why, according Shoshan, there is a close relationship between architecture, public policy and ideology. "[With design,] we can make resources available to communities that are exhausted by militarized conflicts, long periods of drought, famine and disease," she says.
The city has been explored as a theme in movies since the early days of cinema, appearing as both a setting and a protagonist in films by renowned directors like Fritz Lang, Jean-Luc Godard, François Truffaut, Roberto Rossellini and Quentin Tarantino. In one of the first films ever made, Arrival of a Train at La Ciotat (1925), the Lumière brothers already show the modern urban environment as an important element and part of the contextualization.
Yet the cinema and the city have an extensive relationship, each influencing one another. The influence of architecture (especially modern) in the settings and cities of films can be seen in movies like Jacques Tati’s My Uncle (1958) and Ridley Scott’s Blade Runner (1982), while the influence of cinema in architecture and buildings can be seen in the work of architects like Rem Koolhaas, Jean Nouvel and Bernard Tschumi.
We have compiled a list of 10 films in which the city plays a much more important role than just the mere setting, acting as a true protagonist of the plot.
