Balderdash's-Eye: Geographer Pinpoints Center of Northward America
The town of Center, N Dakota, is taking eye phase, thanks to a geographer who has figured out that it's in the dead center of North America.
The finding lays to remainder the decades-old question on the location of the continent's bull'due south-eye. Information technology's a question that has long eluded scientists — in a 1964 report past the U.S. Geological Survey (USGS), for case, experts wrote: "There is no by and large accepted definition of geographic center [of any geographic area], and no completely satisfactory method for determining it."
Non much progress has been made since then, although the USGS has certainly tried. In 1931, the USGS chosen a spot near the boondocks of Rugby, North Dakota (population 2,900), the geographic center of N America, only to update information technology in 1995 to a modest torso of water nearly xx miles (32 kilometers) to the southwest of the town, according to the Wall Street Journal.
Understandably, the question is a hard i. Researchers accept debated whether the center of the continent should factor in North America's islands, and how to account for the constantly changing shorelines. [Globe from Above: 101 Stunning Images from Orbit]
"There are all these people out there saying, 'There'due south no real good way to do this,'" Peter Rogerson, a professor of geography at the University at Buffalo in New York who developed the new geographical method, said in a statement. "[But] equally a geographer, my feeling is that if we want to come upward with a practiced mode of defining a center, we can and we should."
In 2015, Rogerson published a study in the journal The Professional Geographer detailing his novel method — ane that allows researchers to locate the geographic centre of a region, whether information technology is a continent, an island or a country, he said.
The technique accurately takes into account the curvature of the World, Rogerson said. This is important, equally the curvature affects the true altitude between two locations, he said.
Nonetheless, the method doesn't include the continent'southward islands, and instead focuses on the main landmass, he said.
In tardily 2016, Rogerson tried out his method to notice the middle of North America. The result was serendipitously pleasing, given that the point fell in the middle of a small town named Eye (population 570), he said.
Center of attention
A past method that people used to detect a region's center was to balance its cardboard cutout on a needle, Rogerson said.
His method is a scrap more complex. It accounts for the mathematical definition of a geographic center: the spatial equivalent of the center of gravity in physics, he said. Moreover, its location minimizes the sum of the squared distances to all other points in a region, he added. [The Mysterious Physics of 7 Everyday Things]
The technique uses a so-called "azimuthal equidistant map projection," which preserves essential qualities related to distance when a rounded, 3D model of a planet is projected onto a flat, second surface.
Once a second projection was fabricated, Rogerson paired information technology with a reckoner program and established a mathematical formula for locating the centroids of 2nd polygons. This allowed him to narrow down the geographical heart that met the mathematical definition of where a center should be located, he said.
But fifty-fifty this new technique isn't perfect. The azimuthal project assumes that Earth is a sphere, when information technology'due south actually slightly oblong.
"It could ever be more exact," said Rogerson. He added that other scientists may take different approaches to the problem, and that his answer doesn't shut the door to future pursuits.
The town of Rugby and a bar in Robinson, North Dakota, may be glad to hear that. They're in the center of a ferocious battle to be known as North America's geographical center, according to the Wall Street Periodical.
Apparently, being the "center" is good for business, which may explain why so many places don't even bother with being in the center of a continent, and instead claim to exist the middle of the universe, including New York'south Times Square, a spot in downtown Tulsa, Oklahoma, and the Fremont neighborhood of Seattle.
