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%. WebAug 6, 2024 · you may want to try the other approach - turning the s2 processing off - first. It is a quick and dirty approach, may be deprecated in the future and does not resolve the underlying issue (it just reverts to a less sophisticated fallback method) but if you require just a quick plot it may do the trick – Jindra Lacko Aug 6, 2024 at 12:28
