Just off the phone with John Hanke, former CEO of Keyhole, now GM of the Keyhole unit of Google. We spoke about the implications of Keyhole’s acquisition. A few things stand out.
First and foremost, Keyhole is in the Holy Crap That’s A Lot of Data business – that alone is reason for Google to be interested. Their database stands at 12 terabytes and growing. It covers more than 50 percent of the earth’s population, and includes satellite imagery, mapping data, topographic overlays, and, pay attention here, geolocation-based content tags. In fact, in his presentation at Web 2.0, Hanke showed an application, which he called geoblogging, which allows folks to fly around Keyhole’s data and annotate various things they see. “They identify a spot, then talk about it, upload pictures they took there, whatever,” Hanke told me. “That then becomes an icon, a point in the Keyhole database” that others can view and comment upon.

The idea is to bring the Force of the Many and the Architecture of Participation(caveat, PDF download) to a visualization of the earth. Jaw dropping yet? But wait, there’s more. Hanke also showed the overlay of real time traffic information from third party sources, like the CalTrans traffic feed. Mapping data to geography will allow for multitudes of such applications. Imagine Google scaling Keyhole to all web surfers for free, and then opening up the APIs for all to develop on.
