The heatmap shows the places people like, based on the number of panoramio photos at each place in the world. The dark areas have few photos, the red areas have more and the yellow areas have a large number of photos geotagged. The hottest places have markers linking photos, streetview, wikipedia, wikivoyage, foursquare and google plus articles about the site. The place names are selected by the wikipedia readership numbers and foursquare checkins. Area populations are based on the geonames database. Street level heatmaps are available for top 15000 places in the world, sorted by the number of photos in an area of a size of a few square kilometers around the place center.

Ces endroits incroyables sur la planète… Certains dépassent l’entendement au niveau magnificence, d’autres sont plutôt tristes comme certaines photos urbaines… Rien ne vaut la nature, et celle-ci ne sera jamais égalée par l’homme! Great Blue Hole, Belize Horseshoe Bend, Colorado River, Arizona Golden Horn, Brac Island, Croatia CASA Working Paper 197 Visual Analytics for Urban Design Here we outline the rapid development of new tools for visualising cities and their functions with an emphasis on how they can be used in the analytical phases of urban design. We begin with the most obvious examples of digital visualisation – 2D and 3D maps – from geographic information systems (GIS) and computer-aided design (CAD) technologies. These merge into augmented and virtual realities and imply that much of what has been developed for desktop applications is now shifting to the web. We then examine networks, noting the early development of space syntax but then moving to flow systems of various kinds that record interaction between the elements of a design.

Wind Map: Historical An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you a historical snapshot of the delicate tracery of wind flowing over the US. See the live map for current winds. Wind map prints are available from Point.B Studio. Read more about wind and about wind power. Sanskrit alphabet, pronunciation and language Sanskrit is the classical language of Indian and the liturgical language of Hinduism, Buddhism, and Jainism. It is also one of the 22 official languages of India. The name Sanskrit means "refined", "consecrated" and "sanctified". It has always been regarded as the 'high' language and used mainly for religious and scientific discourse. Vedic Sanskrit, the pre-Classical form of the language and the liturgical language of the Vedic religion, is one of the earliest attested members of the Indo-European language family.

GeoSilk GeoSilk is a set of icons designed for open source web-based geospatial software. The set is an extension of Mark James's Silk icons—probably the most widely used set of icons on the web—that incorporates metaphors for spatial constructs defined by Jody Garnett's uDig icons. Take a gander at the full set or download it from the SVN repository. GeoSilk is available under a Creative Commons Attribution 3.0 License, meaning anyone may use it for any purpose and make any changes they like.

Scientists gauge power of mighty asteroid that shaped Earth A monster asteroid, far more massive than the one that drove the dinosaurs to extinction, punched a huge hole in the Earth's crust billions of years ago and triggered global earthquakes that sent waves of towering tsunamis across all the world's oceans. Stanford scientists studying ancient rocks in a region of East Africa known as the Barberton Greenstone have for the first time modeled the asteroid's impact and concluded that it must have been one of the most powerful events to ever shape the face of Earth. The jumbled rocks there hold clear evidence of the stuff thrown up by the asteroid's impact roughly 3.26 billion years ago, but no one has found just where the crater-forming asteroid actually hit, said Stanford geologist Donald Lowe, who has explored the jumbled rocks of the Barberton area for more than a decade.

Your phone could help detect earthquakes Smartphones could soon be used to detect earthquakes, bringing vital early warning systems to some of the world's poorest regions. A new study by the US Geological Survey shows GPS sensors built into phones and other gadgets are capable of detecting ground movement caused by large earthquakes, and could warn people of tremors before they occur. The study, published in the journal Science Advances, outlines the feasibility of such a system using a simulation of a magnitude seven earthquake and data from the 2011 magnitude nine earthquake that hit Japan. The results revealed a crowdsourced earthquake early warning system could be achieved with only a small percentage of people sharing data from their phones.

Carbon map infographic: a new way to see the Earth move How can you map the world to show global data in an immediately clear way? How can you show two datasets at once to see how they compare? Kiln, a partnership of Guardian writer Duncan Clark and developer Robin Houston has come up with this beautiful new take on the globe. Watch the animated intro or click on the topics and see the map move before your eyes.

Big data problems we face today can be traced to the social ordering practices of the 19th century. In the 19th century, changes in knowledge were facilitated not only by large quantities of new information pouring in from around the world but by shifts in the production, processing and analysis of that information. Hamish Robertson and Joanne Travaglia trace the connections between the 19th century data revolution and the present day one, outlining the implications this may have for the politics of big data in contemporary society. Two centuries after the first big data revolution, many of the problems and their solutions persist down to the present era.
