WebWhen spherical geometry operations are turned off, with the command sf::sf_use_s2 (FALSE), buffers (and other geometric operations) may result in worthless outputs because they use units of latitude and longitude, a poor substitute for … WebNov 27, 2016 · Points and Lines. Spherical geometry is nearly as old as Euclidean geometry. In fact, the word geometry means “measurement of the Earth”, and the Earth is (more or less) a sphere. The ancient Greek geometers knew the Earth was spherical, and in c235BC Eratosthenes of Cyrene calculated the Earth’s circumference to within about 15%.

WebIn S2, all edges are “spherical geodesics”, i.e. shortest paths on the sphere. For example, the edge between two points 100 meters apart on opposite side of the North pole goes directly through the North pole.
