Satellite Images Used to Document International Atrocities 171

wikkedwoman wrote with a link to a Washington Post story about the use of satellite imagery to detect atrocities around the world. The story details Amnesty International's efforts to identify areas in the world that may have been subject to man-made disasters. By comparing and contrasting imagery captured over time, researchers can produce hard evidence to present to a hard-to-please international community. "Tonight, [Amnesty Researcher Jeremy] Nelson begins his work by making a copy of the [older] shot in the right-hand screen and pasting it directly over the [newer] one on the left. Then he makes the top one nearly transparent. A river that cuts through the scene becomes a marker to help him line up the two. Now he can easily flip back and forth to look for changes. Sudanese huts tend to follow a similar pattern: a solid base ring with a steep, thatched roof. In the earlier image, they show up as small circles, with a slight shading to the dome, depending on the direction of the sun. Nelson draws a small, green circle slightly larger than the area of the average hut and makes several dozen copies of it ... When he finishes, he moves the 2007 shot to the top and begins the analysis again ... parts of this region were burned so thoroughly that there's nothing left but a large black scar. If you didn't know that huts were there before, you'd have no idea they were now gone. 'Whoever did this did a good job,' he says quietly. 'Thorough, at least.'"

      I would be surprised if something like this isn't automated yet. I can't imagine any decent intel shops running analysis of satellite imagery with humans as first line. The volume of data and risk of intel leaks thru people make automation a more viable option.
      • I'm sure that government intel agencies are doing some automated stuff like this now, but I was thinking of more general applications when the imagery becomes cheaper. Perhaps the local government could send out automatic notices when they spot some homeowner's new addition which violates the zoning law, for example. Or they could see that someone is parking cars on the street overnight in an area that aren't supposed to. Of course there could be lots of private sectors uses as well.

          Should I point out that the lack of light could be a flaw in your otherwise sound reasoning?

          My thoughts exactly, why not use this to determine violations of zoning laws? Searching for a pool can be much easier by the satellite than by driving around. Perhaps it can be used to study traffic flow issues; taking averages from multiple days, understanding the what effect blockages/lane closures have on entire cities, etc.. Would be an interesting proposition.

          • Should I point out that the lack of light could be a flaw in your otherwise sound reasoning?

            True, but if you saw the car there at say 5 PM one evening and then in the exact same spot at 7 AM the next day, and so on for a week running, you could be pretty certain something's been going on.

              Perhaps, but the tolerances would have to be small. If there are lines to park between, or objects (fire hydrants or whatever) then it would be hard to tell if they had moved and returned - or whatever. It is an interesting idea, but there would be a few things to work out. Having a charge hold up in court is another thing.

                Oh, I wouldn't think this would be conclusive evidence in and of itself. Instead it could be used to suggest places to send officers out to, who would issue the tickets themselves after verifying the transgression.

          It depends on the cost of having detailed sat images, regularly updated, versus the benefits of detecting these violations. Thankfully, the expense is way too high for mundane infractions like the ones we all commit now and then :)

    Its great to be able to see exactly whats taken place in Sudan, but it was well know that genocide was taking place. This is just more confirmation. Im not sure what value this has.

    I don't think there is really much debate that there are massacres taking place in Sudan at the moment. However is it very easy for the Government to control the flow of information out of the country. Doctors without Borders, who are often the organization on the front line of these crisis, who are willing to speak up about atrocities, got kicked out in 2005. A UN diplomat (http://www.janpronk.nl/index288.html#290 [janpronk.nl]) was also expelled for blogging about the Sudanese government.

    NGOs have a hard time bringing in any sort of communication equipment (satellites for internet etc etc) and I'm pretty sure that you need to have a permit to take photos in Sudan, and the government controls where people can go. This is the same for many conflict zones, especially those with dubious treatment of human rights.

    What this article shows is that there are now ways of documenting what is going on in Sudan, which is beyond the direct control of the Sudanese government. However it is very expensive (the images are costing about $1600 each) and there was an issue, when they couldn't book satellite time over Sudan. Whether this was because the government booked it out to prevent them from taking photos is unsure - but it does show the limitation.

    Part of the reason that the international community is dragging their feet (or can drag their feet) is probably the lack of reliable concrete information - and this is what this project provides.

    That and the fact that Sudan has oil, which the Chinese are heavily invested in.

    • That and the fact that Sudan has oil, which the Chinese are heavily invested in.
      That's the most insightful post so far on this topic. As long as the Chinese/American/Russian/French/et al. oil companies are getting rich, nobody cares about genocide.
      • A post is not insightful because it agrees with your political belief. Neither oil, nor bush is responsible for all evil in the world. Neither of these 2 have ever touched Sudan more than a tiny bit, so I won't go as far as to say that the exact opposite is the case, but clearly there's at least more than one factor involved here.

        Maybe oil is involved, maybe ... I don't really think so actually. It's just too little oil to realistically matter.

        Of course, realism is something you're not worried about, right

          I don't see how Bush comes into the picture. You also have no idea about my political belief. If you read my comment, I had also mentioned the French, Russian and Chinese oil companies (which means governments in China and Russia). In fact the situation is worse when there is Chinese or Russian oil involved because there is so little media coverage or open discussion about them.

          Let me just point out a few instances when oil may have played a part in recent history.

          • Most of the mess that is currently in the Middle East now is due to promises made to both sides (Israel and the Arabic countries) to keep them from allying with the Axis in WWII. Japan's bombing of Pearl Harbor was the result of our blockade on Indonesia (which was Japan's source of oil). Pretty much since the development of the internal combustion engine/tank/airplane every facet of geopolitics has been primarily about oil. Before that it was about coal (for steam ships).
            • Oh yeah the world would have been *so* much better if USA did not block indonesia. *cough*

              You ARE a white german speaking aryan or a japanese heterosexual non-cripple, right ? Just to check your sanity, and to remind you that it was *not* about oil.

              Yes at one point in the war the supply routes of the armies were an issue. This does *not* mean the war was about oil.
              • The war was most definitely about oil, Germany and Japan needed it, and the Allies sold their souls to the then leaders of the Middle East to keep them from supplying the Axis with oil. I'm very happy that the Allies won, but most of the war was entirely about who would control access to cheap oil in the Middle East and South Asia. A decent amount of the indirect blame why Germany lost was because they were cracking oil (in limited supply) from coal rather than getting it from Saudi Arabia.
                • Doesn't it bother you to be a revisionist ? I mean you cannot seriously think that you're right ... I've yet to see oil mentioned anywhere in the reasons for Germany's attacks. The reason for their attacks was their supremacist and totalitarian ideology.

                  I suppose you're going to say that the cold war was also about oil.

                  As you said, they could, if necessary do without oil. And yet you keep saying this.

                  Same with Japan. They did not join the war to get access to oil. That's bullshit.
                  • Why do you think that we have a strategic petroleum reserve? That oil isn't for regulating the price, it allows a war to take place without imports. Since WWI militaries have depended on oil to operate. Oil was one of the key strategic resources and it was most certaily the reason for the direct engagement of the US/Japan portion of the war.

    • That and the fact that Sudan has oil, which the Chinese are heavily invested in.

      Seriously though, I think China is the major threat to peace and stability in the world today. In addition to Sudan, China is also a major supporter of several other repressive countries in the world, including Burma, North Korea, and Zimbabwe. This includes both arms/military support and political clout in the United Nations. On the bright side, many activists are using the Olympics next year to bring up many of China's domestic and foreign policy issues. It's similar to what happened 19 years ago in Sout

    • the government controls where people can go.

      Actually the government in Sudan doesn't have that much control. As long as a person is willing to risk their life they could enter the Darfur area via Chad or the Central African Republic or southern Sudan via Ethiopia or other nations. And these borders aren't strung with barbed wire fences or have many guards if any. Once inside travel to the center or north of Sudan is where there will be trouble with the government.

Subtracting one image from the other isn't always all that useful sometimes. Overlaying and making something transparent is often the easiest way to see the change between two things.
