Remote Sensing and Land Cover Change

Remote Sensing and Land Cover Change | ApocalypseSurvival | 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.

Amy Marques's curator insight, April 24, 12:46 PM

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, 10:30 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.

Nicole Kearsch's curator insight, October 6, 3:05 PM

This is crazy! Within the short 24 years that have passed since 1990 the Aral sea is just about dried up.  After sliding the bar across the land you can see just how much of the sea has gone dry.  Seeing the little areas of land poking out of the sea in 1990 is interesting, you think that you would have to go very deep to find the bottom, but clearly you don't have to go very far now, as the sea is very close to being dried up.

Image Analysis

Image Analysis | ApocalypseSurvival | Scoop.it
One of a number of large wildfires that have affected northern California in 2012, the Chips fire burned more than 75,000 acres by the time firefighters had contained it.

 

2012 is going to go down in United States history as the year with the most acres burned in a single year (statistics only go back to 1960).  The two featured images were taken earlier this month to display a Northern California wildfire; both with the same spatial resolution and acquired for the same instrument (Advanced Land Imager on EO-1 satellite), yet they are quite distinct.  One shows an aerial photograph, displaying exactly what standard visible portion of the electromagnetic spectrum (showing us what our eyes would normally see).  The other image displays a false color (near infrared) image. 

 

Questions to ponder: what advantages does each image have for analyzing the fire damage?  Drawbacks?  How does the data from both images work together to create a more complete picture of the situation?

Lisa Fonseca's comment, September 17, 2012 10:22 AM
The first image displays a better visual of exactly where the fire damaged the land, the second image doesn't provide a clear visual to someone, the land effected is foggy. If I was going to visit this specific area in Northern California I would much rather use the first aerial image.
Jesse Gauthier's comment, September 17, 2012 10:31 AM
The first image gives a good spatial shot of where the exact hot spots are located that cannot be seen by the naked eye. The second photo will give you a spatial view of what you can actually see. Both are needed to put out the hot spot because they each will provide two different solutions to stop the burning acres.

Book Review: American Apocalypse

Book Review: American Apocalypse | ApocalypseSurvival | Scoop.it
WITH THE ECONOMY IN FREE FALL AND
MILLIONS THROWN OUT OF WORK, AMERICA’S FRAGILE
DEMOCRACY COLLAPSES.
The federal government is left powerless, police and military forces disband, and a once-proud America descends into lawless anarchy. Cities empty. Looting, violence and murder quickly become the norm. And desperate citizens are left to fight for their very survival. Amid the chaos, one teenager finds himself homeless and alone, striving to stay alive on the outskirts of a crumbling Washington, D.C. Forced to adapt by the constant threat of starvation and violence, the young man finds himself developing survival skills he never imagined needing and a moral sense that gives meaning to his struggle. American Apocalypse is a riveting coming-of-age story where one man, against all odds, must find the will to live and, in turn, become a fledgling force of justice.

Good visual representation of what it would take to be self sufficient.

Chris Scott's curator insight, July 14, 2013 9:51 AM

If you need a backyard that is about 2 acres to live off the land imagine how big of a backyard you would need if you had a family of 8.
