Abstract :
His adventure flights over rough mountains yield stunningly accurate maps. Rick Armstrong is snuggled up with a laptop in the cluttered space that was once the backseat of a six-Â passenger Cessna 206. Twenty-Âfive hundred meters below, sun-Âsplashed Portland, Ore., slowly dissolves into the Tolkienesque foothills of Mount Hood. It´s some beautiful scenery. But right now, Armstrong´s eyes are fixed on his computer, which monitors the images that are streaming in from a camera mounted under the belly of the little plane.
