What Happens in Vegas Stays in Vegas? Guess Again!

Dorian Roffe-Hammond sent me this video link from NASA. It shows 40 years of Las Vegas sprawl in about 40 seconds.

I first saw Las Vegas in 1976. Lots of water down the river since then.

From the WWW site:

In honor of Landsat 5's 28th birthday today (March 1st) here's how the desert city
of Las Vegas has gone through a massive growth spurt. The outward expansion of the city is shown in a false-color time lapse of data from all the Landsat satellites.

The large red areas are actually green space, mostly golf courses and city parks. You'll notice the images become a lot sharper around 1984, that's when new instrument designs greatly increased their sensitivity.

These Las Vegas images were created using reflected light from the near-infrared, red and green portions of the electromagnetic spectrum (Landsat 5 TM bands 4,3,2 and Landsat 1-3 MSS bands 4,2,1).

Landsat data have been instrumental to our increased understanding of forest fires, storm damage, agricultural trends, and urban growth. Studies using Landsat data have helped land managers keep track of the pace of urbanization in locations around the world.

The next Landsat satellite, now known as LDCM and later as Landsat 8 is scheduled for a launch in January 2013.

 

It doesn't seem to catch the sprawl to the southeast (Henderson); McCarran International Airport is at the lower right-hand corner.

Wonder where Las Vegas' water problems came from?

As for the title, just ask the folks in eastern Nevada if sprawl stays in Vegas.
