Disaster Mapping: Hurricane Irma, Mexico Earthquake and Bangladesh Floods

Disaster Mapping: Hurricane Irma, Mexico Earthquake and Bangladesh Floods | STEM Connections | Scoop.it

This week has seen disasters and destruction on an unprecedented scale, and the HOT Community has activated to respond. Hurricane Irma is the largest Hurricane ever recorded, and has torn death and destruction through the Caribbean. Destruction on some islands is estimated at 95%, affecting the lives of 1.2 million so far, and on track to cause severe destruction across the entire Florida State, where mass evacuation is currently underway. Barbuda’s prime minister, Gaston Browne, described the damage as absolutely heart-wrenching. 'The island is literally under water and barely habitable,' Browne said. 'About 95% of properties are damaged, there is a serious threat of disease. Additionally, those already affected by Irma fear a second brutal battering by Hurricane Jose.'"

Want to see geographic knowledge and geospatial skills in action?  Crowd-sourced mapping is increasingly an important resource during an emergency.  Poorer places are often not as well mapped out by the commercial cartographic organizations and these are oftentimes the places that are most vulnerable to natural disasters.  Relief agencies depend on mapping platforms to handle the logistics of administering aid and assessing the extent of the damage and rely on these crowd-sourced data sets.  My students and I join OpenStreetMap (OSM) projects, especially when there is a major humanitarian need...it's a great way to make service learning and geospatial technologies come together. The projects that are marked urgent by the Red Cross are all in Haiti right now.  Here are is a video playlist that explains the project and how you can help if you are new to OpenStreetMap (OSM).

Good cartography lies at the intersection of rigorous scientific data display and a aesthetic touch of beauty.  This article is an ode to the beauty of USGS topographic maps as affordable pieces of art.  Geography students that start their own mapping projects need to recognize that good cartographic work often needs to be both an art and a science to fit the needs of their intended audience.

Coast Lines

Coast Lines | STEM Connections | Scoop.it
In the next century, sea levels are predicted to rise at unprecedented rates, causing flooding around the world, from the islands of Malaysia and the canals of Venice to the coasts of Florida and California. These rising water levels pose serious challenges to all aspects of coastal existence—chiefly economic, residential, and environmental—as well as to the cartographic definition and mapping of coasts. It is this facet of coastal life that Mark Monmonier tackles in Coast Lines. Setting sail on a journey across shifting landscapes, cartographic technology, and climate change, Monmonier reveals that coastlines are as much a set of ideas, assumptions, and societal beliefs as they are solid black lines on maps.

Map Projections

Map Projections | STEM Connections | Scoop.it

A map projection is used to portray all or part of the round Earth on a flat surface. This cannot be done without some distortion.  Every projection has its own set of advantages and disadvantages. There is no "best" projection.  The mapmaker must select the one best suited to the needs, reducing distortion of the most important features.  Mapmakers and mathematicians have devised almost limitless ways to project the image of the globe onto paper. Scientists at the U. S. Geological Survey have designed projections for their specific needs—such as the Space Oblique Mercator, which allows mapping from satellites with little or no distortion.  This document gives the key properties, characteristics, and preferred uses of many historically important projections and of those frequently used by mapmakers today.

A More Accurate World Map Wins Prestigious Japanese Design Award

A More Accurate World Map Wins Prestigious Japanese Design Award | STEM Connections | Scoop.it

"To design a map of the world is no easy task. Because maps represent the spherical Earth in 2D form, they cannot help but be distorted, which is why Greenland and Antarctica usually look far more gigantic than they really are, while Africa appears vastly smaller than its true size. The AuthaGraph World Map tries to correct these issues, showing the world closer to how it actually is in all its spherical glory."

Seth Dixon's curator insight, November 1, 2016 2:03 PM

This just shows how subjective the concept of "accurate" can be. First off, this is a fabulous map that nicely minimizes distortions (distance, direction, area, and shape) of the land on our planet. Any criticism of the map just shows the impossibility of making an accurate 2D map of a 3D Earth, but I still think that there is plenty of room to discuss the flaws/distortions that were chosen instead of others. It is interesting to note that a Japanese contest awarded this map with it's top honor (I doubt a Brazilian organization would feel the same way about this map). This map does make with some traditional cartographic conventions in its representation of Earth.  

 

Questions to Ponder: What are some elements of this map that are different from more traditional maps? This map claims to be more accurate; does that make it more useful?

Yes, these globes are precise archives filled with geospatial data and locational information--however, that pales in comparison to the artistic brilliance of the globes. These hand-crafted globes are truly works of art.  Marvel at the merger of mathematical precision and artistic design that makes a globe such as these a cartographic gem.   If anybody want to get me a Christmas present, you know that I love cartographic gifts.

This is an interesting article on some Earth-Sun relationships that challenges the dominant north-centered normative view of how to think about our planet.  My favorite tidbit of information: "The velocity of the Earth’s rotation varies depending on where you stand: 1,000 mph at the Equator versus almost zero at the poles. That means that the fastest sunrises and sunsets on the planet occur on the Equator, and centrifugal and inertial forces are also much greater there. "
