EARTH Masterpieces

The natural landscapes shown as captured by satellite imagery is as beautiful as anything artists have ever created.  Some of the colors shown in the video may seem otherworldy.  Most of those color anomalies are due to the fact that remotely sensed images have more information in them than just what we see in the visible portion of the electromagnetic spectrum.  Some of these images are processed to show different bands so we can visually interpret data such as what is in the near infra-red band, skewing the color palette.

Black Marble: The Earth at Night

Black Marble: The Earth at Night | general geography | Scoop.it
“Nothing tells us more about the spread of humans across the Earth than city lights.”...

 

"For three weeks spread out over April and October of this year, the Suomi NPP satellite (jointly of NASA and NOAA) scanned all the Earth's land as it appeared at night. Scientists then mapped the satellite's data -- 2.5 terabytes of it -- over an earlier Blue Marble image, transforming that picture's daytime blues, browns, and greens into a nightime palette of blues, blacks, and gold." 

 

This video is a great compliment to the classic Earth at Night composite image as well as the adjusted cartogram for population density.  

 

Questions to Ponder: What do these lights "tell us" about human geography?  What does the intensity of the lights indicate?
