The Mercator projection is a map projection that was widely used for navigation since loxodromes are straight lines (although great circles are curved). The following equations place the x-axis of the projection on the equator and the y-axis at longitude , where is the longitude and is the latitude. There is also a transverse form of the Mercator projection, illustrated above (Deetz and Adams 1934, Snyder 1987). It is given by the equations Finally, the ‘universal transverse Mercator projection’ is a map projection which maps the sphere into 60 zones of each, with each zone mapped by a transverse Mercator projection with central meridian in the center of the zone. The zones extend from S to N (Dana). Explore thousands of free applications across science, mathematics, engineering, technology, business, art, finance, social sciences, and more.
