Google's GeoEye-1 Takes Its First Pictures 152

Posted by timothy from the seattle's-beauty-would-damage-the-sensors dept.
Kev92486 writes "I was scanning through my RSS feeds today and happened upon an article about Google's GeoEye-1 imaging satellite which launched on Sept 6. Intrigued as to what the quality of the image was like, I decided to check it out only to find that the first picture was actually of my college campus, Kutztown University (Pennsylvania).
I had to make sure I was reading the article correctly as Kutztown is not a very large or well known campus. I'm not sure as to why they chose Kutztown for their first pictures. I would be interested if anybody could provide some sort of insight as to what process was used to select the first test location. Was the satellite simply in a convenient orbit to snap pictures of Kutztown?" Update: 10/09 20:56 GMT by T : HotHardware has its own article up on GeoEye-1, if you'd like your words and pictures in the same place.

    Don't be coy, we all saw the lead up to this in the papers earlier this year [imageshack.us]. Kutztown's had this coming--it was one thing to invite Putin to talk but when he left those trailers, that was too far.

    On a serious note, I'm certain they picked Kutztown based on the following:

    Let P denote the number of lawyers a university has on reserve.

    Let Q denote the number of lawyers Google has on reserve.

    Let R denote said university's reserve resources for emergencies.

    Let L be a function such that L(x) = the number of lawyers one can immediately hire with x dollars.

    Is P + L(R) Q? Then I think we have a candidate! I found it on Google Scholar.

It seems that the wind farm company paid for a high resolution survey of the area and that just got added to the data pile.

      Is there something wrong with the angle? Sun-synchronous orbit means that each time the satellite appears over that same university campus, it will do so at the same time of day. So, unless you see multiple shadow angles implying that the image was taken over multiple passes and that the shadow angle changed with each pass, I don't see what's specifically unimpressive about the orbit. Can you explain your observation?

          Sun-synchronous orbits are extremely common for optical imaging satellites. A sun-synchronous orbit simply means that the satellite crosses the equator at a specific time of day on every orbit. The sun-synch time can be chosen at will; you can make it any time that you want. If you choose noon, you get very short shadows; if you choose a time early or late in the day, you'll get long shadows. The length of the shadows at any give spot the Earth (away from the equator) changes with the season (because the

    • You can only take photos without shadows at one point on the earth at any given time: specifically, the area immediately around where your satellite's shadow is projected onto the earth. Sun-synchronous orbit just reduces the number of shadows you're likely to see, unless you're always imaging directly downwards. This picture is taken north west of the satellite's shadow, so the buildings have shadows too.

    The actual image collected was a 16 km wide swath cut through PA and part of New York. The swath was chosen based on timing and that it would be fairly close to nadir. As for why Kutztown in particular, I'll ask around, but I think it was basically just something interesting to look at(read:not trees). The calibration and focus were probably pretty good at that point in the image too. Keep in mind this is literally the very first image from the satellite, using preliminary calibration and focus, with the color bands aligned by hand. The imagery from this satellite is going to be exceptional once everything is said and done.

        The nadir angle is basically how far to the side the satellite is pointing from its ground track. The farther off nadir the more you're looking at the sides of buildings and trees vs. the top. You're generally off a bit, but anything above 30 starts to get useless for most things.

The other sensor has the same native resolution, but shares it between one of four multi-spectral bands (Red, Green, Blue, Near-IR). This is why the MS (multi-spectral) resolution for each band is exactly 4x lower than Pan band -- 1.64m vs 41cm.
