The '''Adams hemisphere-in-a-square''' is a [[Conformal map|conformal]] [[Map projection|map projection]] for a hemisphere. It is a transverse version of the [[Peirce quincuncial projection]], and is named after American cartographer Oscar Sherman Adams, who published it in 1925.<ref>{{citation|title=Cartographic Science: A Compendium of Map Projections, with Derivations|first=Donald|last=Fenna|publisher=CRC Press|year=2006|isbn=9780849381690|url=https://books.google.com/books?id=8LZeu8RxOIsC&pg=PA357|page=357}}.</ref> When it is used to represent the entire sphere it is known as the '''Adams doubly periodic projection'''. Like many conformal projections, conformality fails at certain points, in this case at the four corners.
