Atlas of ReUrbanism

Buildings and Blocks in American Cities

As the National Trust’s ReUrbanism initiative seeks to build the successful, inclusive, and resilient cities of tomorrow, the Atlas of ReUrbanism is a tool for urban leaders and advocates to better understand and leverage the opportunities that exist in American cities.

The Atlas of ReUrbanism takes the massive amount of data currently available about cities and makes it more accessible, allowing for the exploration and discovery of connections between older buildings and economic, demographic, environmental measures. Whether you’re an activist, journalist, developer, or resident, the Atlas of ReUrbanism contains detailed information about the businesses and residents, buildings and blocks that make cities work for everyone.

The Atlas of ReUrbanism was supported through the generous financial contributions of the Jessie Ball duPont Fund, the Kresge Foundation, and the Richard H. Driehaus Foundation.

New York Times: 50 Maps of the U.S. Cultural Divide

If you had to guess how strongly a place supported Donald J. Trump in the election, would you rather know how popular ‘Duck Dynasty’ is there, or how George W. Bush did there in 2000? It turns out the relationship with the TV show is stronger.

That’s how closely connected politics and culture can be.

A Database of World Events

From Trajectory Magazine:  http://trajectorymagazine.com/got-geoint/item/2294-a-database-of-world-events.html

Imagine a database that holds information on all world events and historic records reported in the global news media over the last 30 years, along with the narratives, emotions, and images that defined those events. What you’re envisioning is the real-life GDELT project.

GDELT—which stands for Global Database of Events Language and Tone—is a free, open data platform that applies machine learning to gather news from all over the world and curate what GDELT creator Kalev Leetaru calls “a catalogue of society.”

“Today, we have sensors and satellites blanketing the earth, we know what the weather is, when an earthquake happens, and how many people are affected,” Leetaru said. “We have so much data about the natural Earth, but when it comes to the human Earth, to cataloging human ‘earthquakes’ like mass protests or coups, we were in the stone ages. Before GDELT we never had a database that could give you a list of all the protests happening right now around the world. That’s the goal of GDELT—to let you see the human world just as well as you can the natural world, letting you map global protests as easily as you can map global earthquakes.”

Leetaru began working with supercomputing and web mining in 1995 when he launched his first Internet startup. In 2013, he developed GDELT, and it has been his main focus ever since. Leetaru is also a senior fellow with George Washington University’s Center for Cyber & Homeland Security.

GDELT has evolved beyond its original scope, and now collects broadcast, print, and web news and images from around the world—updating every 15 minutes. Several different data sets bring together more than 400 million event records in 300 categories, more than a trillion emotional measures, two billion mentions of location, and more than 175 million images covering world events from 1979 to present.

GDELT captures the emotion and tone of the articles and images. The project brings together a number of algorithms to detect the author’s emotion in an article, ranging from traditional positive/negative to more complex emotions such as anxiety and motivation. The database also distinguishes the emotion of an image—for example, whether it is violent or if the people in the image are looking away in horror.

GDELT identifies and disambiguates every location mentioned in each article, which can be used to map the geography of specific topics such as wildlife crime or civil unrest.

“Wildlife crimes are fragmented and groups are doing their own thing with little communication, never being able to put it all together to see the big picture,” Leetaru said. “Being able to use GDELT and see the patterns and what’s happening around the world puts the dots on the map and the context behind it in order to see where poachers will strike next. That’s the power of GDELT.”

GDELT is available for anyone to use for free. The GDELT cloud-based analysis website offers a number of built-in visualizations users can leverage to explore the data. Users can also download the raw files on the GDELT website or explore any of the GDELT data sets via Google BigQuery.

Open Source Tool Will Help Drive Emission Reduction

From Informed Infrastructure:

A new research project seeks to develop a tool to identify and reduce carbon in the construction supply chain. The project is a collaboration between the University of Edinburgh Business School and Costain Group and is funded by the Construction Climate Challenge (CCC) initiative hosted by Volvo Construction Equipment.

The Carbon Infrastructure Transformation Tool project (CITT) started from the need to solve two key problems facing the construction industry – the pressing need to reduce GHG emissions, and the highly fragmented nature of supply chains.

“In large infrastructure projects there are large amounts of emissions at stake. The supply chain is also very fragmented, with many different stakeholders. It’s important to ensure we have a consensus across the whole chain to reduce emissions,” says Dr Matthew Brander, Lecturer at University of Edinburgh Business School and Project Manager for CITT.

The research project seeks to develop and implement a tool that will help construction companies identify and reduce carbon. It will pinpoint opportunities to reduce carbon through innovation and supply chain engagement. It will also enhance the amount of communication and dialogue across the supply chain.

Swarm Satellites Discover ‘Jet Stream’ in Earth’s Core

Swarm Satellites Discover ‘Jet Stream’ in Earth’s Core

Using data from the European Space Agency’s three Swarm satellites—which measure the different magnetic fields that stem from Earth’s core, mantle, crust, oceans, ionosphere and magnetosphere—scientists discovered a jet stream deep below Earth’s surface that’s increasing in speed.

“It’s the first time this jet stream has been seen, and not only that—we also understand why it’s there,” said Phil Livermore from the University of Leeds and lead author of the paper published in Nature Geoscience.

One of the discoveries is a pattern of “flux patches” in the northern hemisphere, mostly under Alaska and Siberia, which make it easy to see changes in Earth’s magnetic field.

Swarm reveals that these changes are actually a jet stream moving at more than 40 kilometers a year—three times faster than typical outer-core speeds and hundreds of thousands of times faster than Earth’s tectonic plates.

This jet stream flows along a boundary between two different regions in the core. When material in the liquid core moves towards this boundary from both sides, the converging liquid is squeezed out sideways, forming the jet.
