I’m not sure why I’m so intrigued by Google’s acquisition of satellite image provider Keyhole, but I am. Perhaps it’s because it’s one more sign that Google generally operates at the very edge of the search space, looking for ways to push those edges outward; perhaps it’s because it’s another huge data set that I’m sure hasn’t been sufficiently examined. Or perhaps it’s for one of the dozens of other reasons related to information mining, the places where wildly dissimilar data sets meet, and all the cool tools that Google’s made to date. In any event, I’m anxious to see what comes of it.
