The Best Resources On Different Types Of Map Projections I’m teaching Geography again to English Language Learners, and though I’d pull together some accessible resources on the different kinds of map projections. You might also be interested in The Best Online Tools For Comparing The Physical Sizes Of Different Countries. Here are my picks – contribute your own in the comments section: Your World Map is Hiding Something is a very useful interactive from Metrocosm which allows you – with a click of a button – to compare different kids of popular (and not-so-popular) world map projections. Here’s a lesson plan from National Geographic. This is a great video for Geography classes, BUT I wish the narrator didn’t talk so fast!
7 maps that will change how you see the world A Japanese architect has won a prestigious award for creating a new map, because it shows the world as it really is. The AuthaGraph World Map angles continents in order to show their true distance from one another. Image: AuthaGraph World Map Hajime Narukawa won the Good Design Award, beating over 1,000 entries in a variety of categories. “The AuthaGraph World Map provides an advanced precise perspective of our planet,” explain the organizers of the award. Not only that, but the map can then be transformed into a globe.
The Best Online Tools For Comparing The Physical Sizes Of Different Countries Photo credit Last week I published a popular post titled “The True Size Of” Is A Must-Use Site In Every Geography Class about a new site that lets you easily compare – accurately – the sizes of different countries. Reader John Padula then left a comment mentioning that there were also two similar sites, so I thought a short “Best” list would be in order. Where in the world are we? A brief exploration of cartography – Boston University News Service Setting foot inside Boston Public Library’s Norman B. Leventhal map collection is like stepping into a condensed vignette of human exploration, or perhaps an extra-detailed version of high school history. The library houses 200,000 maps from all corners of the globe (if you’ll pardon the expression); myriad records spanning—and illustrating—history. The sheer number is testament to the 2,000-plus year pursuit to develop a more accurate two-dimensional representation of our 3-dimensional planet.
24 hours of global air traffic in 4 seconds On an average day, there are roughly 90,000 commercial flights around the world. This stunning animated map displays them all in 4 seconds. Every plane flight in the world over 24 hours The AuthaGraph World Map Isn't Perfect, But It's Pretty Close Creating a proportional map of the world is tricky because the world is a sphere and a map is flat. That creates visual distortions, which explains why Mercator projections shrink Africa and super-size Greenland. Designer Hajime Narukawa found a clever solution to this problem: triangles. Narukawa’s AuthaGraph World Map, which recently won the grand prize in Japan’s biggest design competition, retains the proportions of the continents and oceans—so much so that you can fold it into a three-dimensional globe. Like magic! He achieved this by dividing the globe into 96 triangles and projecting them onto a tetrahedron, preserving the proportions of water and land.
Your World Map is Hiding Something Take a look at a map of the world. If it looks like this one, as most do, you will see that Alaska appears larger than Mexico and that Greenland looks about the same size as Africa. In reality, Mexico is larger than Alaska and Africa is about 14x the size of Greenland. The maps below show how their true sizes compare (images from The True Size Of). The “normal” world map is actually very strange Because the world is a sphere, it is impossible to draw it on a flat surface without distorting it in some way. Map projections: A working manual Abstract After decades of using only one map projection, the Polyconic, for its mapping program, the U.S. Geological Survey (USGS) now uses several of the more common projections for its published maps. For larger scale maps, including topographic quadrangles and the State Base Map Series, conformal projections such as the Transverse Mercator and the Lambert Conformal Conic are used. Equal-area and equidistant projections appear in the National Atlas. Other projections, such as the Miller Cylindrical and the Van der Grinten, are chosen occasionally for convenience, sometimes making use of existing base maps prepared by others.
Map Overlays Comparing Size All maps face the challenge of making the globe appear to scale in two dimensions. Most, like the traditional Mercator projection, keep either size or shape consistent — not both — which skews our perception of continents and countries one way or the other. But when you compare square mileage, a whole new world appears. Inspired by this map of Africa's true size from German graphic designer Kai Krause, we created 11 map overlays to open your eyes to some real geography. Mike Nudelman/Business Insider
