That was my first thought - NASA's done incredibly high resolution surveys of the US (and most of the Earth) in the past coupla decades - but I'm not sure how useful they'd be in border determinations. I know also that we're losing some land in places due to soil erosion (often because of problems maintaining the coastal tree lines) but I'm not sure how much of that is on there. I'm not even sure what constitutes "land" in this context... is it everything between the borders? Does it include lakes? Swamps? Marshes? How deep does water have to be before it's not counted as "land" in that case?
