Maps. They’ve been around longer than photographs. They’ve defined empires,guided explorers, told stories, and captured the imagination of many a hopeful traveler for years. While most appreciate the beauty and power of a good map, few recognize the dynamic and vital applications they have today.

Map Projections

Map Projections | Geography Education | 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.

Seth Dixon's insight:

This article chronicles 18 map projections, how they are mathematically rendered with their own unique set of advantages and disadvantages. 


Questions to Ponder:  Why do map projections matter?  Is one global map projection inherently better than the rest?  What is your favorite?

Without mental maps, we’re lost

Without mental maps, we’re lost | Geography Education | Scoop.it
Elwood was a senior geographer working on the ground-floor of the very global positioning systems (GPS) and geographic information systems (GIS) he will throw up for discussion in his TEDx talk.

His question: Are we surrendering our innate mental map making abilities to technology and relying on and trusting it too much? And for TEDx audiences only, he’ll toss out ideas on ways to prevent that from happening.

The mind is a terrible thing to waste.

Wyatt Fratnz's curator insight, March 18, 2015 8:08 PM

This text tells about a geographer who exaggerates today's modern dependency of Global Positioning Systems and Mapping, and the importance of still developing a mental map. It is important because lack of reliance of our mental maps leads to a primal fear and increasing instances of the feeling of being lost. The challenge is presented of how we stimulate technology in our mental maps. 

 

This article describes technological and mental process of mapping and how we should use it in our everyday lives. This is important because it gives humans a sense of direction and tells us how to keep it.

Carlee Allen's curator insight, March 26, 2015 6:20 PM

This is an article that explains and adds on to the fact that we Americans have begun too reliant on technology. Keith explains how kids now a days don't have a geographical sense and how it is really going to hurt them in the future.

 

I thought that this article was interesting, because it is a pretty controversial topic and very relatable.

Mapping the Way to a More Equal World

Mapping the Way to a More Equal World | Geography Education | Scoop.it
Inequality isn't just about money. It's also about information. The lack of reliable data about developing countries makes things like development work and disaster relief much harder.
Seth Dixon's insight:

There is 'mapping inequality' throughout the world; poorer countries often don't have comprehensive census information and geospatial data.  Crowd-sourced mapping is seeking to change and improve geographic awareness, especially in moments of crisis.  For example the maps of Sierra Leone, Liberia and Guinea were essentially blank at the beginning of the Ebola outbreak but that glaring need meant volunteers were using geographic tools to improve developmental situations by providing more information.

Speaking the “Language” of Spatial Analysis via Story Maps

Speaking the “Language” of Spatial Analysis via Story Maps | Geography Education | Scoop.it

"Spatial analysis has always been a hallmark of GIS, the 'numerical recipes' which set GIS apart from other forms of computerized visualization and information management. With GIS we pose questions and derive results using a wide array of analytical tools to help us understand and compare places, determine how places are related, find the best locations and paths, detect and quantify patterns, and even to make spatial predictions."

Seth Dixon's insight:

GIS is a key tool in spatial analysis, but it can also be a driving force in using math, science, technology and (yes) geography as interdisciplinary ways of teaching the curriculum.  StoryMaps can be rich with images and videos, but also filled with data at a variety of scales.  ESRI has share a "Maps we love" page with excellent examples of Story Maps and carefully explains WHY these maps work and HOW they were made.  Are you new to using the Analysis tool in ArcGIS Online?  Try this exercise on analyzing flood risk to guide you through some of the steps to learn what is possible for a project of your own.  What stories can you tell in this rich, visual format?  What visual template shown might lend itself best for that sort of project?

Unbelievable, tremendous resource. I wish I had this one growing up. It is a US gov site (EPA), and is for US geography. I'm betting you can search around for similar sites for other locales around the world. Great demo. Demo runs on Adobe Captivate. The demo took a little bit of time to load on a wired connection through a high speed fiber optic connection. Or skip the demo and play around with the maps. Site not all that fast. Still, it's worth waiting for if you want the data.

Logging and Mudslides

Logging and Mudslides | Geography Education | Scoop.it
In recent decades the state allowed logging — with restrictions — on the plateau above the Snohomish County hillside that collapsed in last weekend’s deadly mudslide.
Seth Dixon's insight:

There are several reasons for mudslides--some are purely a result of physical geography and others are related to land use patterns.  This last week's mudslide in Washington state was a combination of the two and although this impacts one place (see on map), it is a good teaching moment to discuss the environmental impacts of land use patterns and resource extraction projects.  As seen in this interactive, the river was cutting at the base of the hill, while loggers were clear-cutting at the top of the mountain.  Trees help prevent erosion as the roots hold the soil in place--a critical piece to the puzzle in a very rainy climate.  With $1 million worth of timber on the slope, logging companies persisted despite objections from the Department of Natural Resources and some restrictions (but in hindsight, those restrictions clearly were not enough). 


View the impact in ArcGIS online: Before and After Swipe, LiDAR I and II, and Imagery.


Questions to Consider: Other than economic worth, what other ways are there to value and evaluate the environment?  How could this landscape have been protected and managed better or was this mudslide inevitable?

The Future of Remote Sensing?

"We are pleased to introduce the world's first high-resolution HD video of Earth taken from a commercial remote sensing satellite.

This video showcases a selection of the first videos taken from SkySat-1, the first of our planned 24 satellite constellation. The video clips have not yet been calibrated or tuned. SkySat-1 captures up to 90-second video clips at 30 frames per second. The resolution is high enough to resolve objects that impact the global economy like shipping containers, while maintaining a level of clarity that does not determine human activity."

Seth Dixon's insight:

Most remote sensing videos show still images that are animated to give the temporal sequence a video-like quality.  Technology is changing rapidly and this video represents an impressive leap in our ability to monitor changes on Earth's surface.  To read more about SkyBox Imaging and their plans, click here.

Max Minard's curator insight, March 21, 2015 11:00 PM

Over the past years, remote sensing has established major innovations such as capturing the world's first high-resolution HD video of Earth taken from a satellite. Within the link, a video is shown to show the viewer the exact HD video taken and portrays detailed depictions of the world's surface along with labels pertaining to these specific locations. What this means for the future of remote sensing is that geographers can now access high resolution videos of any part of the world from remote sensing technologies located in space. These innovations show the bright future of geographical technologies and opens the door to many possibilities people can take to further improving remote sensing.

This is where we need more people like Pooh who question everything. Pooh sees where he wants to go with his own eyes and can tell that rabbit is leading him the wrong way. This is relateable to so much in geography but to keep it simple ill compare it to Pythagoras proclaimed the earth was spherical. He question something everyone in the world took as a fact and nobody believed him because it was already stated that the world was flat. Just like pooh questioning the "offical map"

These are the questions that plague geographers.).  True, this map has it's limitations; Instagram hashtag data isn't normalized so the biggest cities tend to pop out more easily, access/use of Instagram isn't uniform, etc.  Still, what a great map to show some geographic applications of social media data.  This sort of map also nicely shows the spatial concepts of region, diffusion, concentration and distribution.

Why Map Projections Matter

Seth Dixon's insight:

This is a clip from the TV show West Wing (Season 2-Episode 16) is a classic--how often does cartography plays a key role in the plot of a TV show?  In this episode the fictitious (but still on Facebook) group named "the Organization of Cartographers for Social Justice" is campaigning to have the President officially endorse the Gall-Peters Projection in schools and denounce the Mercator projection.  The argument being that children will grow up thinking some places are not as important because they are minimized by the map projection.  While a bit comical, the cartographic debate is quite informative even if it was designed to appear as though the issue was trivial. 


Questions to Ponder:  Why do map projections matter?  Is one global map projection inherently better than the rest?

"The Great Circle Mapper displays maps and computes distances along a geodesic path. It includes an extensive, searchable database of airports and other locations."

Seth Dixon's insight:

The shortest distance between two points is not a straight line…well, that depends on your map projection.  A flat map always distorts something when representing our three-dimensional Earth—whether it is distance, direction, shape or area—something gets distorted on our maps.  A great circle is the shortest distance between two points on the surface of a sphere, so that’s going to be the quickest travel route between points (which is why so many airline routes seem to arc).  This website Great Circle Mapper generates great circles that show the shortest distance between two points on many map projects will be an arc.  Why does this particular route arc ‘bend’ north for a while and then south?  Get out a globe for added perspective.

Because this route from JFK Airport to SYD AUS Airport is not a straight route there are many factors that need to be taken in account because of the overwhelming idea of trade winds and how that affects flight plans and routing for different airways/airlanes.  The plane has to fight against the trafe winds in order to create a specific ETA for the passenger and the flight crue among the plane. This is all dependent upon the trade winds (prevailing and other kinds) transmitting against the plane.

In New Hampshire they are doing great work to make mapping data useful in the classroom.  This site is one that they use to show how students can map locally relevant data from an online data set.  CoCoRaHS (Community Collaborative Rain, Hail & Snow Network)  is a crowd-sourced network that gathers North American precipitation data.  The data (especially the total precipitation summary) can be easily copied into as spread sheet and saved as a CSV file (which can be uploaded to ArcGIS online).

This is  COCORAHS. people from different places put this measurement tools to measure the rain fall, and it is different everywhere. this is cool in my opinion.
