Many of Evans’s humorous stories go a way to responding to some of the scientific inadequacies and toponymic foibles so common in place naming studies. And after I’ve spent almost a decade inundated with often sterile and uninspirational place name theory and how it may fit within more general research in onomastics, the study of proper names, Evans’s tongue-in-cheek take is more than welcome.
I get the distinct impression that this is a less-serious work of scholarship than Monmonier’s. [WMS]
Decades of continental drift mean that GPS coordinates in Australia are off by approximately 1.5 metres (5 feet), which has implications for self-driving cars and other applications that require very precise positioning. See coverage from Atlas Obscura, BBC News, Popular Mechanics and the Washington Post.
Basically, the discrepancy comes from the fact that GPS is based on the Earth’s core rather than any point on the surface, whereas local coordinates are based on a geodetic datum—in Australia’s case, GDA94 (North America uses NAD83)—that is based on a fixed point on the surface. But with plate tectonics, points are not fixed: Australia moves northward at seven centimetres a year.
