YouTube Video of Landsat Satellite Images of Las Vegas (1984-2009)

I came across this animated slideshow last week and felt it was worthy to share here. I have an old USGS book that uses earlier Landsat satellite imagery showing roughly the same thing, but this version is newer and shows more growth. What I thought was the most interesting, beyond the fact that human growth looks like cancer, is seeing Lake Mead shrink considerably over the years. When you watch the video above, look closely at the lake on the far right side to see what I’m talking about. This begs the question, as Las Vegas grows and Lake Mead shrinks, will or should the city stop growing when the water runs out? Since its a man-made reservoir, I doubt it will go dry up anytime soon, but I guess the larger issue to me is how sustainable can living in the desert really be? There is quite a bit of space in the Las Vegas area that has yet to built on, but should it be? Should there be a limit to the growth of the city so that the city become less dominated by low-density housing? If people want cookie cutter houses I can’t say much about their tastes, but I will say that there is a carrying capacity of all environments and I’m curious about when and if Las Vegas will reach that level.

Short NASA video of the 2004 Transit of Venus

Since I started reading about the Transits of Venus, I’ve found this video on-line in multiple places, but no one has uploaded it to Vimeo yet. This very short video is composed of a sequence of images taken by the Solar X-ray Imager on the GOES satellite as Venus passes between the Earth and the Sun. If you look closely, that small ball at the bottom is Venus. The last Transit of Venus before this was in 1882 and the next transit will take place on June 6th, 2012, where it should cross the upper portion of the Sun.

I was recently directed to the the National Archives’ Digital Vaults webpage. After the flash animation was loaded up, I was greeted by a nice visual interface (above) that shows various items that are digitally scattered within the vault.

Using the elements from the Lenz Projection I was able to magnify portions of a tessellated Messier 101 Pinwheel Galaxy (a grand design galaxy) to create this fine celestial perspective.

San Francisco Memory revisited

So yesterday my sister asks me if I can get her imagery of San Fran for her school project. This afternoon I tried going to the USGS and had their web-based GIS not work properly, so I gave up attempting to acquire the imagery. Later today (like 4 hours later), I found an old CD that was laying on top of my TV and I realized that CD had the “San Francisco Memory” rendering on it. So I opened it up, and to my amazement, the spot at which the earth and the ocean meet near the center of the rendering is where the property she is working on is located. On March 5th, I created special memory….

I think my sister is going to love this print. Slowly but surely, I’ve rendered images of all the locations my family is located. In the full size version of this rendering, you can actually see my sister’s apartment! I think my favorite aspect of this rendering this the way the Golden Gate Park appears to give some rectangular symmetry. Here is a Google Map of the same area:
The source image from Space Imaging was rotated so the resulting rendering has Golden Gate Bridge at both the top & bottom center. Of course the full size version allows one to see the bridge in better detail. This is my third rendering of this series.
