Le portail des territoires et des citoyens. Our Changing World. Mapping Proportional Geographical Data. Reading a blog post by Jon Udell just now - Visual numeracy for collective survival - I came across this question: What do you call th[e] kind of [map] projection, where country size is proportional to a variable?

Mapping Proportional Geographical Data

What do you call something like this, for example? Any ideas? How would you search for it? I started off for a search on "proportional country map", and was lucky enough to soon hit upon an explanation by scanning through the search results: this type of map is called a cartogram, and it's one of several ways of using a map to depict the value of some particular measure or statistic. Visit the Worldmapper website, which hosts a collection of several hundred different cartograms (some of which are reprinted in The Atlas of the Real World: Mapping the Way We Live) and see if you can find cartograms that estimate the distribution of telephone lines across the world towards the end of the 20th century and in the early years of the 21st century.

Mapping Stereotypes Project by alphadesigner. Crazy Maps Show The World Organized By Human Activity. Ever since Gerardus Mercator created his iconic map of the world in 1569--the one that first enabled ships to navigate at sea without getting lost--people have been drawing maps using the same fundamental concept of conveying physical space.

Crazy Maps Show The World Organized By Human Activity

Cartographers have gotten more sophisticated over time. They’ve figured out how to distort that space, how to portray that Massachusetts has more electoral votes than Wyoming, or that countries closer to the equator are larger than we think. But for hundreds of years, we’ve been tethered to the idea of looking at the world through the shape of its land. Now that there’s virtually none of that left to explore and discover, it may be time to start thinking about our world in new visual ways: not according to physical space, but to how people are distributed across it, and what their presence can tell us about global poverty, health inequality, environmental impacts, and geopolitics.

40 Maps That Will Help You Make Sense of the World

Maps can make a point resonate with readers and this collection aims to do just that. Hopefully some of these maps will surprise you and you’ll learn something new. A few are important to know, some interpret and display data in a beautiful or creative way, and a few may even make you chuckle or shake your head. 1. Where Google Street View is Available 2. 3. 4.

Système d'information géographique

Pour les articles homonymes, voir SIG. La bonne appréhension et représentation du relief est une valeur ajoutée de plus.Modélisation en fausse 3D avec ombrage (dérivée d'une base de données topographique) (Région de Valestra, dans les Alpes du nord, Italie) Un système d'information géographique (SIG) est un système d'information permettant de créer, d'organiser et de présenter des données alphanumériques spatialement référencées, autrement dit géoréférencées, ainsi que de produire des plans et des cartes.

Ses usages couvrent les activités géomatiques de traitement, de partage et de diffusion de l'information géographique. La représentation est généralement en deux dimensions, mais un rendu 3D ou une animation présentant des variations temporelles sur un territoire sont possibles. La personne responsable d'un SIG, dans une structure (publique comme privée), est appelée « sigiste » ou bien « géomaticien ». Historique[modifier | modifier le code] Your Open Source Compass.
