Spherical cube earth
WebThe quadrilateralized spherical cube (QLSC) is a geospatial indexing scheme for segmenting a sphere into pixels with the aim of optimized spatial indexing and queries. QLSC is an implementation of this scheme in a Python package. Parts of it are based on code from Sergey Koposov’s Q3C, a PostgreSQL extension that implements QLSC indexing. WebFeb 10, 2011 · There's a map projection called the Quadrilateralized Spherical Cube that's used in astrophysics to represent all-sky maps. It has a nice property that the pixels are within a few percent of having equal …

WebJan 1, 2011 · The discovery of the spherical shape of the earth is the finishing touch of the new world picture that was introduced by Anaximander. Strictly speaking, it is not right to use the word “discovery,” since the idea of a spherical earth, as we will see in this and the next chapter, was the product of metaphysical speculations, rather than a discovery … WebMay 28, 2014 · The QLSC is a mathematical construct for the division of the six spherical squares on a sphere into equal-area cells by an appropriate (nonlinear) transformation from the equal-area cells on the six planar squares of an inscribed cube.
WebJan 13, 2024 · (And, yes, we’re ignoring the fact that the Earth isn’t a perfect sphere and its surface isn’t exactly smooth.) On a sphere, straight paths follow “great circles,” which are geodesics like the equator. If you walk around the equator, after about 25,000 miles you’ll come full circle and end up right back where you started.
