Images of the social and economic world

Here is an ordinary map of the world: Click on image for a larger version Roughly speaking, on a map like this, the sizes of the countries of the world are in proportion to their actual sizes on the surface of the planet and their shapes are the same as their actual shapes. (This is only approximate though, since some distortion is inevitable when you go from a spherical planet to a flat map.) It's possible, however, and sometimes very useful, to redraw the map with the sizes of countries made bigger or smaller in order to represent something of interest. Here, for example, is a cartogram that shows the human population of the countries of the world: Population In this map the sizes of countries are proportional not to their actual landmass but instead to the number of people living there; a country with 20 million people, for instance, appears twice as large as a country with 10 million. Gross domestic product Now here are a few more cartograms. Child mortality People living with HIV/AIDS

Wind Map 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 the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. If the map is missing or seems slow, we recommend the latest Chrome browser. Surface wind data comes from the National Digital Forecast Database. If you're looking for a weather map, or just want more detail on the weather today, see these more traditional maps of temperature and wind.

India Grows, Canada Disappears: Mapping Countries By Population : Goats and Soda Can you find Australia and Canada? The cartogram, made by Reddit user TeaDranks, scales each country's geographic area by its population. (Click through to see the high-resolution map.)

Take a spherical object (the Earth) and try to represent it on a flat plane (paper), and some parts of the sphere are going to get stretched. Every now and then, though, you stumble across a map that enlightens.

Animated Historical Maps The first Christian communities (1st century) This map is part of a series of 17 animated maps showing History of Christianity. 4 are currently available online Independence for India and Pakistan Clement Attlee, the Labour Prime Minister who replaced Winston Churchill in July 1945, soon realised that independence for India was inevitable, but disagreements among the Indian politicians made the negotiations very difficult. This map is part of a series of 14 animated maps showing Decolonization after 1945 The circumference of the Earth and the Route towards the West In the 3rd century BCE, Eratosthenes calculated the circumference of the Earth with remarkable precision. In later centuries, other Greek geographers, including the most famous of them all Ptolemy, suggested a much lower figure for the circumference for our planet. This under-estimation was adopted by 15th century map-makers. This map is part of a series of 16 animated maps showing The Age of Discovery (Part I) Europe Plunges into War

Slippy Map Slippy map Slippy Map is, in general, a term referring to modern web maps which let you zoom and pan around (the map slips around when you drag the mouse). Here we often talk about "The Slippy Map" to mean the map display on the openstreetmap.org front page. This is a web interface for browsing rendered OpenStreetMap data. By default the slippy map shows tiles rendered in our "standard" OpenStreetMap style, but you we offer several other featured tiles as layers to select and to link to. See the Browsing page for more basic help information on how to use the slippy map and link to it. Technical details Tile rendering The process of rendering, going from vector to raster map data, baking style choices into bitmap images, is a fairly resource-intensive process. OpenStreetMap "Standard" tile server Mapnik is the rendering software used for generating the "standard" OpenStreetMap style. The standard tiles are generated on tile.openstreetmap.org. See also

Rcartogram Rcartogram_0.2-2.tar.gz This is an interface to Mark Newmans cartogram code, and the technique of Newman and Gastner. This is used to produce spatial plots where the boundaries of regions can be transformed to be proportional to density/counts/populations. This is illustrated in plots such as Mark Newman's plot of People living with HIV/AIDS and Michael Gastner's Cartogram of the US House of Representatives election, 2008 The technique is described in a paper. This is currently a basic (and quickly implemented) interface to the cartogram code. Download The source for the package is available via Rcartogram_0.2-2.tar.gz. Documentation Changes Demo We create a simple matrix (200 x 200) divided into 5 regions, with a rotated circle (or square) in the middle. As we can see, the boundaries of the regions change in a non-linear manner. The code is in the demo/ directory of the package and can be run with demo(synthetic, package = "Rcartogram").
