The Guyou hemisphere-in-a-square projection is a conformal map projection for the hemisphere (except for the four angles of the square where the conformality fails). It is an oblique aspect of the Peirce quincuncial projection. When it is used to represent the entire sphere it is known as the Guyou doubly periodic projection (see also doubly periodic function).

Famous quotes containing the word projection:
“In the case of our main stock of well-worn predicates, I submit that the judgment of projectibility has derived from the habitual projection, rather than the habitual projection from the judgment of projectibility. The reason why only the right predicates happen so luckily to have become well entrenched is just that the well entrenched predicates have thereby become the right ones.”
—Nelson Goodman (b. 1906)
