I was looking for satellite images of last weekend’s blizzard and found that today’s MODIS Satellite Image of the Day just so happens to be of the Washington, DC area. MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites that documents changes on the surface of the earth. Terra’s orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth’s surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths that are used for numerous scientific purposes. You can view these satellite images in real-time and see exactly what has happened on the surface of the earth within the last 48 hours.
Geoeye satellite image showing where I was located at the 2009 Inauguration of Barack Obama

At around 11:19AM on January 20th, 2009, GeoEye‘s newest satellite, GeoEye-1, took this picture of the inauguration of president Barack Obama in Washington, DC. Since it was taken before the start of the swearing-in ceremonies, you can see that crowds were still making their way into the viewing areas. In the next hour after this satellite image was taken, I was able to make my way to the ticketed viewing area, but only after a lot of hard work! I will write about how I made it in, while thousands of others did not, in an upcoming entry.

About a month ago I made the first version of the map using the Western Hemisphere. At the time I didn’t even think about making a secondary map for the Eastern Hemisphere.
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.

This is my first redesign of the “star of..” series. I added two more rings and now it almost looks like a molecule! I think its absolutely gorgeous. I can’t wait to get it printed!!
