[8] The legacy of Tissot’s method is still vivid today, as suggested by the authors of Map Projections for Europe, who argue that since Tissot’s famous analysis regarding distortion, the only major scientific development in the metric interpretation of deformation has been Eduard Imhof's Verzerrungsgitter, or deformation grid.

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 ...
Direct application of the orthographic projection yields scattered points in (x, y), which creates problems for plotting and numerical integration. One solution is to start from the ( x , y ) projection plane and construct the image from the values defined in ( λ , φ ) by using the inverse formulas of the orthographic projection.

The sinusoidal projection with Tissot's indicatrix of deformation Jean Cossin, Carte cosmographique ou Universelle description du monde, Dieppe, 1570 The sinusoidal projection is a pseudocylindrical equal-area map projection , sometimes called the Sanson–Flamsteed or the Mercator equal-area projection .
Each state has its own set of reference parameters given in the standard. [ 8 ] The U.S. National Geodetic Survey 's "State Plane Coordinate System of 1983" uses the Lambert conformal conic projection to define the grid-coordinate systems used in several states, primarily those that are elongated west to east such as Tennessee .
