Cartography: The true true size of Africa

Cartography: The true true size of Africa
LAST month Kai Krause, a computer-graphics guru, caused a stir with a map entitled "The True Size of Africa", which showed the outlines of other countries crammed into the outline of the African continent. His aim was to make "a small contribution in the fight against rampant Immappancy"—in particular, the fact that most people do not realise how much the ubiquitous Mercator projection distorts the relative sizes of countries. A sphere cannot be represented on a flat plane without distortion, which means all map projections distort in one way or another. Some projections show areas accurately but distort distances or scales, for example; others preserve the shapes of countries but misrepresent their areas. You can read all the gory details on Wikipedia. Gerardus Mercator's projection, published in 1569, was immediately useful because it depicts a line of constant bearing as a straight line, which is handy for marine navigation.

Are the Richest Americans Also the Best Educated? More Infographics on Good Commission on Mountain Cartography Päivän kuva 16.10.2013: Kuinka suuri on Afrikka? | Tiedetuubi Toki tiedämme, että Afrikka on suuri manner, mutta kartat antavat yleensä hieman valheellisen kuvan siitä, miten iso se oikeasti on. Tietokonegraafikko Kai Krause teki elokuussa tämän kartan, missä Afrikan kokoa hahmotetaan sijoittelemalla muutamia muita maita sen sisään: sinne mahtuvat hyvin mm. USA ja koko Eurooppa. Siinä missä 1600-luvun merenkävijät olivat hyvin tyytyväisiä Gerhardus Mercatorin vuonna 1569 esittelemään karttaan, nyt sitä käytetään vain siksi, että siihen on totuttu.

This Is What A World Map Looks Like When Scaled According To Population Size Where in the world did Australia go?! A new cartogram by Redditer TeaDranks rescales the world’s countries according to population size instead of geographic area. Reconstructing maps based on different variables can be a powerful tool for understanding the world we live in. In this case, certain regions almost disappear from the map while others expand considerably; Canada transforms into a thin, jagged line while India now takes up a massive amount of space. Other interesting tidbits: North Korea has a larger population than Australia, with 25.1 million people compared to 23.7 million, respectively. “I was inspired by this map which is now ten years old,” said TeaDranks. It is important to note that even modern world maps distort the Earth. To check out a high-resolution version of the map, click here.

The Greek Kangaroo - Journal Income inequality, as seen from space Last week, I wrote about how urban trees—or the lack thereof—can reveal income inequality. After writing that article, I was curious, could I actually see income inequality from space? It turned out to be easier than I expected. Below are satellite images from Google Earth that show two neighborhoods from a selection of cities around the world. Rio de Janeiro Rocinha Zona Sul Oakland West Oakland Piedmont Houston Fourth Ward River Oaks Chicago Woodlawn Hyde Park Beijing Fengtai Chaoyang Boston metro area, Massachusetts Ball Square, Somerville West Cambridge Your examples Do you have other cities or neighborhoods in mind? Be sure to include the names of the cities and neighborhoods you’re highlighting and if you’d like me to mention your name. Your examples are now posted!

Choosing the best way to indicate map scale By Aileen Buckley, Mapping Center Lead In a previous blog entry, I asked, “Do all maps need a scale bar and north arrow?” I answered, “No” and talked a little about direction indicators like north arrows, but I didn’t really go into any detail about scale bars. Almost all maps are drawn to a scale, so it should be possible for these maps to indicate what the scale of the map is. Three primary scale indicators If the map is NOT drawn to scale (that is, the scale varies widely across the map), then it is even more important that you indicate that this is the case! All map scale indicators can be used 1) to determine the extent to which a geographic region has been reduced from its actual size and 2) to help the map reader determine distance on the map. Scale bars, also called bar scales, look like a small ruler on or near the map. A scale bar can be used like a small ruler to determine distances on maps. Example of a variable scale bar for a map using a Mercator projection. Design Uses

Suomen maisemamaakunnat Suomen maisemamaakunnat ja maisemaseudut. Suomen maisemamaakunnat on valtakunnallinen aluejako, jonka Suomen ympäristöministeriön asettama maisema-aluetyöryhmä laati vuonna 1993 työvälineeksi arvokkaiden maisema-alueiden etsimiseksi ja arvottamiseksi. Suomi on jaettu kymmeneen maisemamaakuntaan, joista osa jakautuu edelleen seutuihin. Maisemamaakunta ja -seutujakoa apuna käyttäen ja niihin nähden edustavuuteen pyrkien valtioneuvosto on nimennyt Suomesta 158 valtakunnallisesti merkittävää maisema-aluetta.

Enjoy! If the world’s population lived like… Shortly after I started Per Square Mile, I produced an infographic that showed how big a city would have to be to house the world’s 7 billion people. There was a wrinkle, though—the city’s limits changed drastically depending on which real city it was modeled after. If we all lived like New Yorkers, for example, 7 billion people could fit into Texas. If we lived like Houstonians, though, we’d occupy much of the conterminous United States. Here’s that infographic one more time, in case you haven’t seen it: What’s missing from it is the land that it takes to support such a city. It turns out that question is maddeningly difficult to answer. But what we can do is compare different countries and how many resources their people—and their lifestyles—use.

Mapa: La geografía de las palabras - Los cartógrafos han sabido durante siglos la importancia de la organización de la información temática por el contexto geográfico para poder visualizarlo en un mapa. Un mapa temático le permite comprender la dinámica espacial de un tema dentro de una estructura que tiene fuertes puntos de referencia en la experiencia humana - una miríada de lugares y regiones de todo el mundo. Al mismo tiempo, un mapa temático nos puede mostrar las relaciones importantes entre estos lugares ya que son similares o difieren con respecto a alguna propiedad de interés. Pero Frankenplace no es sólo una herramienta de cartografía temática. El mapa de calor de arriba es el resultado de escribir ‘Santiago de Compostela’ en Frankenplace. Haz clic para accedera al mapa La versión actual de Frankenplace indexa más de 1,6 millones de artículos a partir de la versión en Inglés de Wikipedia y entradas de blogs de viajes en línea (octubre de 2014).

Mobiilisti maailmaan -toimintamallien esittely by Juhani Kärki on Prezi map_what_europe_would_look_like_if_all_the_separatist_movements_got_their This article originally appeared in Business Insider. The Scottish independence movement will embolden other active separatist groups in Europe to win their freedom, whether or not Scotland votes to secede from the UK on Thursday. From Catalonia and Basque Country in Spain to Veneto, South Tyrol, and the island of Sardinia in Italy to Flanders in Belgium, "the precedent of the vote on self-determination will reverberate around the Continent," the New York Times writes.
