In cartography, the method by which a spherical shape is represented as a rectangle was invented by whom?
History of cartography to use his method. In 1761, the British clock-builder John Harrison constructed the first marine chronometer, which allowed the method developed by Frisius. Triangulation had first emerged as an efficient method in cartography (mapmaking) in the mid sixteenth century when Frisius set out the idea in his "Libellus de locorum describendorum ratione" ("Booklet concerning a way of describing places"). Dutch scientists Jacob van Deventer and Willebrord Snell were among the firsts to make systematic use of triangulation in modern surveying, the technique whose theory was described by Frisius in his 1533 book. Gerardus Mercator is considered as one of the
Rectangle eight". The interior of a crossed rectangle can have a polygon density of ±1 in each triangle, dependent upon the winding orientation as clockwise or counterclockwise. A crossed rectangle is not equiangular. The sum of its interior angles (two acute and two reflex), as with any crossed quadrilateral, is 720°. A rectangle and a crossed rectangle are quadrilaterals with the following properties in common: In spherical geometry, a spherical rectangle is a figure whose four edges are great circle arcs which meet at equal angles greater than 90°. Opposite arcs are equal in length. The surface of a sphere in
