Remote Sensing and Land Cover Change

Remote Sensing and Land Cover Change | Walkerteach Geo | 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.

Luke Walker's insight:

See how much the Aral Sea has changed due to the impact of humans on their environment for yourself. Drag the slider tool to see a before and after. Reference your textbook (p61) for the whole story.

The Aral Sea is literally shrinking before our eyes and people are doing very little to stop it. Due to years of poor farming techniques (growing cotton and rice in this dry climate) the Aral Sea is literally being sucked dry by these crops. People can do very little about it because growing these crops represents their well being. It is a Catch 22 situation...
Amy Marques's curator insight, April 24, 9:46 AM

This map is a true testament to the people who believe human activity does not affect the earth. Humans have been transforming Earth’s surface for years, through direct activities such as farming, mining, and building, and indirectly by altering its climate. Much of the transformation taking place in the Aral sea leads to its connection to the Soviet era and their lack of understanding of the environment. This mismanagement of the Aral Sea is leading to a lack of water for the people who live in Central Asia.

Jess Deady's curator insight, May 4, 7:30 AM

The colors seen in photographs and images like this is because of the equipment used. Sometimes the quality of the equipment makes the pictures look different than they actually are. This basin has dried up over time and its surface has signs of significant change.

A Rio Runs Through It: Naming the American Stream

A Rio Runs Through It: Naming the American Stream | Walkerteach Geo | Scoop.it

Displayed is a map originally produced by Derek Watkins.  This map is a fantastic combination of physical and cultural geography.  While most flowing bodies of water will be called rivers or streams, the lesser used terms (brook, fork, bayou, run, arroyo, etc.) show a striking regionalization of toponym regions.  What do these patterns indicate?  Why are in those toponyms found in those particular places?

Really? Water is everywhere instead of people fighting able I think we should come to together and find a cheap, effective way to purify salt water with the ice caps melting and turning into salt water I think we should be looking into ways to convert salt water to fresh water
