The Behrmann projection with Tissot's indicatrices The Mercator projection with Tissot's indicatrices. In cartography, a Tissot's indicatrix (Tissot indicatrix, Tissot's ellipse, Tissot ellipse, ellipse of distortion) (plural: "Tissot's indicatrices") is a mathematical contrivance presented by French mathematician Nicolas Auguste Tissot in 1859 and 1871 in order to characterize local ...
Nicolas Auguste Tissot (French:; March 16, 1824 – July 14, 1907) was a French cartographer, who in 1859 and 1881 published an analysis of the distortion that occurs on map projections.
Two-point equidistant projection of the entire world with Tissot's indicatrix of deformation. The two points are Rome, Italy and Luoyang, China. The two-point equidistant projection or doubly equidistant projection is a map projection first described by Hans Maurer in 1919 and Charles Close in 1921.
The Peirce quincuncial projection with Tissot's indicatrix of deformation. The Peirce quincuncial projection is the conformal map projection from the sphere to an unfolded square dihedron, developed by Charles Sanders Peirce in 1879. [1] Each octant projects onto an isosceles right triangle, and these are arranged into a square.
The Lambert conformal conic projection with standard parallels at 15°N and 45°N, with Tissot's indicatrix of deformation. Aeronautical chart on Lambert conformal conic projection with standard parallels at 33°N and 45°N.
English: Map of the world in an equirectangular projection with Tissot's Indicatrix of deformation. Each red circle/ellipse has a radius of 500 km. Scale : 1:5,000,000
English: Map of the world in a Lambert cylindrical equal-area projection with Tissot's Indicatrix of deformation. Each red circle/ellipse has a radius of 500 km. Scale : 1:5,000,000
An Aitoff projection of the world The Aitoff projection with Tissot's indicatrix of deformation. The Aitoff projection is a modified azimuthal map projection proposed by David A. Aitoff in 1889.
