The Earth is Square is upset that the Google Earth team gets recognition for its efforts in the wake of Hurrican Katrina. World Wind did it better, he argues. I can’t comment on the relative merits of the World Wind community’s efforts, as I wasn’t aware of them. Clearly, most rescue professionals in the field ended up using Google Earth’s solution at the time — maybe TEiS can explain why that is beyond alluding to better marketing on the part of Google — at that time, the popularity of Google Earth was due overwhelmingly to word of mouth. Is it Google Earth’s ease of use? Is it because Google’s servers could handle the extreme load?
