Remote Sensing and Land Cover Change

Remote Sensing and Land Cover Change | APHG EMiller | Scoop.it

By moving the slider, the user can compare 1990 false-color Landsat views (left) with recent true-color imagery (right). Humans are increasingly transforming Earth’s surface—through direct activities such as farming, mining, and building, and indirectly by altering its climate.


This interactive feature includes 12 places that have experienced significant change since 1990.  This is an user-friendly way to compare remote sensing images over time.  Pictured above is the Aral Sea, which is and under-the-radar environmental catastrophe in Central Asia that has its roots in the Soviet era's (mis)management policies.

Clearly the water level has decreased in Kazakhstan from 1990 until now. Farming, mining, and building are all indirectly changing the geography of some places. The use of rivers for cotton irrigation has shrunk by 3 quarters in the last 50 years and it is extremely affecting the Aral Sea.

Is sad to see how humans are changing the environment forcing the wild creatures to abandon the places they've been living for hundred or years or die of starvation. I wonder what will happen in 300 years when there is no more big lakes and the oceans will be completed polluted .

Great tool to show students how human use of natural resources can change landscapes and have permanent impacts on geographical landmarks such as the aerial sea. How do we stop it? Can we undo the damage done? How do we prevent these tragedies from happening in the future?

Why Map Projections Matter

This is a clip from the TV show West Wing (Season 2-Episode 16) where cartography plays a key role in the plot.  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?

I think it is very important that we start using more accurate maps. In school, the maps we use are so different from how the world actually is. I agree that children will grow up thinking some places are less important because they are minimized by the map projection.

Great clip. I use it in my WRG class as a comedic introduction to the power of projection.

This absolutely the best video clip for SS teachers EVER!

A History of Conflicts

A History of Conflicts | APHG EMiller | Scoop.it
Browse the timeline of war and conflict across the globe.

 

This database of global wars and conflicts is searchable through space and time.  You can drag and click both the map and timeline to locate particular battles and wars, and then read more information about that conflict.  This resource would be a great one to show students and let them explore to find what they see as interesting.  This site is brimming with potential.

Oh... You are lucky ;-)

the potential of this site is amazing between the interactive learning system and the correlation between the timeline and location. If the human geography class is anything like this i can't wait for it!

Selecting a Map Projection

Selecting a Map Projection | APHG EMiller | Scoop.it
Video. Cartographers at National Geographic discuss how they select an appropriate map projection for the September 2012 magazine map supplement.

 

There is no one perfect map projection that fits all circumstances and situations. Think a situation in which this map projection would be an ideal way to represent the Earth and another situation where it is an incredibly limited perspective.

I have tried geocaching and it really does make you use geospatial tools. You have to know exactly where you are in reference to a map, you have to know directions in which you must travel, and you know you have to reach a certain place. While a fun activity, it is also a great geographic learning tool.

unit 1 nature and perspectives of Geography 

This video relates to unit 1 because of its description of Geocaching, a vocab word of this unit, which is a high tech treasure hunting game where people use gps to find and identify little boxes that were hidden in the surroundings.

This relates to unit 1 because it is a defining example of globalization and helping a group of people come together in their environment. This is also an example of contagious diffusion because of the beginning spread of this invention, which spread rapidly and in an outward direction.
