"The Most Amazing High Definition Image of Earth Ever," Says NASA

"The Most Amazing High Definition Image of Earth Ever," Says NASA | Antarctica | Scoop.it
NASA has released a new Blue Marble image, showing the United States of America. According to them, it's the "most amazing, highest resolution image of Earth ever." Blue Marble 2012 bests the 2010 edition and the original one.

 

Beautiful image...follow the link for a video of the image at a variety of scales as well as the specs and production that went into it.   There is an 8000 x 8000 pixel version as well as many lower resolution versions.

Early World Maps

Early World Maps | Antarctica | Scoop.it

I typically would not link to a Wikipedia article, but this one is not only well crafted, but represents an academic collaborative work in its own right.  This a fabulous cartographic gallery that explores the history of geographical thought through the ages (as archived in the earliest maps).  Enjoy the maps, and even more, the intellectual context that this article provides for each of these images.

Penguins from Space: A New Satellite Census Doubles the Known Population of Emperors

Penguins from Space: A New Satellite Census Doubles the Known Population of Emperors | Antarctica | Scoop.it
High-resolution imaging has allowed scientists to produce the first full count of Antarctica's emperor penguins...

 

Before this, there was no way to to gather reliable penguin statistics.  Geospatial technologies are now providing us the tools to teach us more about the biogeography of penguins.  The applications of geospatial technologies are endless.

Gregory S Sankey Jr.'s curator insight, September 1, 10:22 AM

Our world is changing rapidly. Both due to human activity and natural climate patterns. It's important to be able to quantify the effects of this change in order to understand how our world will continue to change. If we can correlate these specific changes in climate and weather patterns and declining/rising species populations we may be able to protect important species in decline and manage those on the rise. Using geospatial technologies is vital in studying these changes and will only improve and become more valuable in time.

Jacob Crowell's curator insight, December 16, 7:48 AM

In the beginning of the semester we talked about how geography is always changing. Our understanding of geography does as well. This new technology helps people have a clearer picture of the wildlife that exists on Antarctica. Because of its harsh environment the amount we know about this barren continent has been limited. As technology improves we will be able to gain more accurate information about Antarctica.

Hector Alonzo's curator insight, December 16, 12:58 PM

Using this new technology, animal can be monitored and helped by the satellites. Having a way to accurately know the population of a species is incredible,  because now we can know which species are in danger of extinction and we can take steps to help them. Before the use of the satellite,  the population of Emperor penguins was found to be 595, 000 and the colonies of penguins was found to be 46 instead of the previous 38, so without this technology there have been penguins that may have needed help, but now they will get proper attention.
