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. He devised Tissot's indicatrix , or distortion circle, which when plotted on a map will appear as an ellipse whose elongation depends on the amount of ...
Tissot was founded in 1853 by Charles-Félicien Tissot and his son Charles-Émile Tissot in the Swiss city of Le Locle, in the Neuchâtel canton of the Jura Mountains area. [2] The father and son team worked as a casemaker (Charles-Félicien Tissot) and watchmaker (Charles-Emile). His son having expressed an interest in watchmaking from a young ...
Mathey-Tissot no longer produces its own watch movements in house. Instead, the company customizes mechanical and quartz watches with movements sourced from others. [4] Its logo is similar to the "peace symbol" of the Campaign for Nuclear Disarmament, but turned upside-down, with the words Mathey-Tissot in manuscript, above the printed words "since 1886".

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 ...
Tissot's indicatrices on the Mercator projection The classical way of showing the distortion inherent in a projection is to use Tissot's indicatrix . For a given point, using the scale factor h along the meridian, the scale factor k along the parallel, and the angle θ ′ between them, Nicolas Tissot described how to construct an ellipse that ...
Tissot's most famous work in his lifetime was Avis au peuple sur sa santé (1761), arguably the greatest medical best-seller of the eighteenth century. [5]On 1 April 1787, Napoleon Bonaparte wrote to Dr. Tissot complimenting him on spending his “days in treating humanity” noting that his “reputation has reached even into the mountains of Corsica” and describing “the respect I have ...
