"Google Satellite" To Be Launched This Week 280

Lord Satri writes "Well, almost. Google signed an exclusivity deal with GeoEye regarding GeoEye-1, the most advanced high-resolution, civil, remote-sensing satellite to date. This must be annoying for other high-resolution, remote-sensing data users since Google already has an exclusivity deal in place with DigitalGlobe, the other major civil satellite imagery provider. From the CNet article: 'Under the deal, Google is the exclusive online mapping site that may use the imagery... in its Google Maps and Google Earth product. And as a little icing on the cake, Google's logo is on the side of the rocket set to launch the 4,300-pound satellite in six days from Vandenberg Air Force Base in California. Terms of the deal weren't disclosed. GeoEye-1 will orbit 423 miles above Earth, but it will be able to gather imagery with details the size of 41 centimeters... Google, though, is permitted to use data only with a resolution of 50 cm because of the terms of GeoEye's license with the US government.'"

        The only reason it's evil is because it ultimately relies on copyright law. This exclusivity agreement would be worthless if Google couldn't prosecute people using the images they display to provide a competing service.

        Contrariwise, there would be anti-competitive elements to an open agreement as well. There would be basically no opportunity for satellite competition, due to massive barrier to entry and smart pricing schemes by GeoEye. An exclusivity deal means lower resolution satellite data still has buyers, and google competitors could support the launching of another satellite.

        Honestly, it is hard to trade things like this without exclusivity. You wouldn't want to buy rights to have Michael Phelps on your cereal if he also said he would appear on every other brand of cereal for whatever price they were offering. It would be worth basically nothing to everyone, whereas, with exclusivity, it is at least worth something to someone. Likewise, there is no point in google or anyone else throwing billions at GeoEye to become the highest resolution online map service if GeoEye then licenses the same data to everyone. It may be that the value of the data in such a scenario is not even enough to finance the satellite launch, in which case, the possibility of exclusivity is definitely a beneficent aspect of the market--giving consumers a product that would simply not exist without it.

        Anyway, one really must debate the merit of anti-competitive policies concerning something google is giving away for free. It's not as though the market is going to drive down the price of "free."

    Some precisions on my summary. DigitalGlobe is obviously not the only other remote sensing data provider, but it's GeoEye main competitor in civil high-resolution multispectral remote sensing. GeoEye is itself the merging of two other previous major players on the same playing field, OrbImage and Space Imaging [slashgeo.org].

    As for my claim of an agreement between DigitalGlobe and Google, see this two years old entry [slashgeo.org]. The original archive for the DG message is here [osdir.com] (the link on /geo does not work anymore).

    One of the obvious questions that comes to mind is to which extent these exclusivity deals have negative impacts on other remote sensing imagery customers, small or big.

    Another question is; does Google really needs such a deal to provide the best webmapping and virtual globes-related tools?

          50cm is like half a meter. Most people are under 2 meters tall, and between 50cm and 100cm wide. So if you had a resolution of 50cm, you wouldn't see a 'lady sunbathing in the nude' you'd see 1x4 to 2x4 block of colored pixels. Try to draw a 'woman sunbathing in the nude' using 8 pixels. Now using 4-8 pixels draw each of 'borat wearing a g-string', a pig, a camel, a litter of cocker spaniels, a beige hammock, and a cardboard box and explain how to tell them apart.

          For comparison the 'mario' in the original Nintendo "Super Mario Brothers" was around 400 pixels. And they had to dedicate the entire top 3rd to his head just so that he'd have a discernable eye, nose, and moustache.

      My understanding is that at 50cm resolution, an object that is 50cm across would appear as a single pixel on the image. So, a manhole cover in the street might show up as a single pixel at that resolution. A car's hood might be four pixels, etc. Objects that are smaller than 50cm should not be detectible, especially if they are close to the same color as the background. However, if you zoom in on almost any American city to maximum resolution on google maps's satellite view, you will clearly see traffic lines. Traffic lines are roughly 10cm wide. Often these resolve to two pixels.

      So, either my understanding of satellite photo resolution is wrong, or Google can already go to 10cm, and possibly even 5cm resolution.

        the diffraction effect is not the only issue; but its worked-around.

        recently, there were 'multiple exposure' (roughly) algorithms being used to 'look thru' the heat, pollution and general waviness of the sky, in plotting out celestial objects.

        and even *with* diffraction, you can overcome it with sharpening. I often shoot my photos 'with too high an f-stop' according to common theory; but my post-processing overcomes the diffraction issues in practice; and I get the nice large depth-of-field that I was after with quite good sharpness, as well.

        if you get multiple shots, exposures or angles of a subject, you can 'subtract out' quite a lot of noise and distortion. single shots can't do this but multiple ('high dyn range' or HDR) shooting can.

      Defining optical resolution from space is a bit tricky, as several generations of optical engineers have discovered.

      The main criterion is the telescope's point spread function - this is roughly the angular diameter that a pinpoint star appears to be, as seen through the telescope. We want the smallest point spread function, and it should map onto about one to three sensor pixels. (arguments go here about over/undersampling).

      The Fourier Transform of the point spread function is the Optical Transfer Function, which is a graph of the spatial frequencies response of the telescope. It's analogous to a hifi's frequency response ... it's an engineering challenge to prevent high frequencies from getting rolled off.

      The main limit for high resolution is the diameter of the primary mirror (All mirrors and optical elements, no matter how perfect, have diffraction effects which spread out the light and reduce resolution. The bigger the entrance pupil, the greater the resolution) For the GeoEye, orbiting at 684Km and a resolution of 0.4m, I roughly calculate the primary mirror is somewhere around a half-meter diameter or so, depending on the wavelength of light it's optimized for.

      Other things limit resolution - scattering of light in clear air (Rayleigh scattering) screws up the image, especially in the blue. Dust, haze, clouds and urban pollution are a bother, but not as much as you might think. Naturally, there's lots of image processing software ... quite compute intensive.

      A typical human, seen from above and not casting a shadow, is about 20 to 60 cm across. So someone walking down the street should appear on a few (1 to 5) pixels. Not enough to recognize someone, especially since you're looking down on 'em.

      Generally, images taken from aircraft have better resolution (they're closer, and there's less Rayleigh scattering). Perhaps airlines will attach automated, downward looking hires cameras to their daily flights.

But to do that it would have to dip pretty low, causing small(but significant over months/years) drag. Also, I'm commenting on the new Google Satellite while test driving the new Google Browser
    • The interesting thing is that in order to get such an orbit, it has to pass over other countries. Will Google take footage of other countries? If so, will it use that footage? That would probably require some intense international negotiations.

      What?
      Of course they'll use those pictures (footage is for video).

      If other countries do not want Google to put them online, they'll have to come and say so.
      Google has already been asked/told by various countries to lower the resolution of sensitive military installations, because Google didn't do so for non-US/Euro countries.

      Long story short: If you don't want something to be visible in satellite photos, cover it up or put it underground. Governments know to do this by now.

      Actually, it will not. I'm not sure if it's codified anywhere in international law or just by historical precedent, but a nation's airspace does not extend into space. A satellite can legally take photos of anything it can see, and there's little a country can do about it except hide things under cover or shoot it down (which likely would be considered an act of war).

      Some countries (like the US) can exert control in limited ways by restricting operations if the imaging company does business in the country, but that's it.

      Google has quite detailed satellite photos of Pyongyang, North Korea - I'm sure they didn't really agree to that.

      Most satellites for earth observation use sun-synchronous orbits. These orbits let the satellite's cameras take pictures ob objects at the same solar time. This means that it will pass overhead at the same local time every day ... so the images will have the same shadow characteristics.

      You accomplish this by making the orbit precess exactly 360 degrees per solar year.

      These orbits are typically nearly circular, but needn't be; you can put a spy satellite into a sun-synchronous elliptical orbit, so it'll swoops down and photograph near perigee, then waste a lot of time around apogee.

      Since this orbit is around 684 Km, it can be shown that it must be pretty close to circular, has an orbital period of around 100 minutes, and its inclination is probably about 96 to 100 degrees (meaning that the satellite is slightly retrograde - 90 degrees inclination is polar, zero degrees is equatorial) In turn, this means that pretty much all of earth will be seen by the satellite, except for 8 degree circles around the poles.

      A 96 minute period means that each successive orbit will look down on a place 15 degrees west ... one time zone to the west.

      Geosynchronous orbits are pretty useless for this type of work, since they're so far away (you need really big telescopes to get much resolution). Also, you'd only see one hemisphere, and half the year it'd be nighttime over the areas you want to see.

    I was just referring to the Chrome logo as that - and then this happened. Serendipity, I say. Heh. Or, at least, synergy.
