- The stereographic projection was exclusively used for star charts until 1507, when Walther Ludd of St. Dié, Lorraine created the first known instance of a stereographic projection of the Earth's surface. Its popularity in cartography increased after Rumold Mercator used its equatorial aspect for his 1595 atlas.

The origin of the stereographic projection is not known, but it is believed to have been discovered by Ancient Greek astronomers and used for projecting the celestial sphere to the plane so that the motions of stars and planets could be analyzed using plane geometry.

Most maps adopt one of two possible strategies: (1) areas are preserved, or (2) angles are preserved. Stereographic projection is one way of making maps, and it preserves angles. It has been used since ancient times for this purpose, and its basic geometrical properties were known even then. 1.
This chapter starts by providing an historical introduction by looking at the origin of the stereographic projection (Claudius Ptolemy and the Planispherium). It looks at great and small circles and stereographic poles.
• Hipparchus first described the stereographic project used for an astrolabe around 150 BCE. • Around 150 CE Ptolemy describes an instrument very similar to an astrolabe. • In the 4th century Theon of Alexandria writes a treatise on the astrolabe. • John Philoponus’ 6th-century work on the astrolabe is the oldest surviving text.
Stereographic projection is a powerful method for solving geometric problems in structural geology. Unlike structure contouring and other map-based techniques, it preserves only the orientation of lines and planes with no ability to preserve position relationships.
He realised that accurate coordinates of places were required to draw accurate maps and that the greatest problem was in computing the longitude. He proposed the method of lunar distances to determine longitude which was an important proposal.
