Answer: Mercator projection
Explanation: The Mercator projection is a type of cartographic projection devised by Gerardus Mercator in 1569 to make maps of the earth´s surface. It has been widely used since the 18th century for nautical charts because it allowed to draw the routes of constant or loxodromic course as straight and unbroken lines, unlike other more precise projections.
Mapping web applications, such as Google maps, OpenStreetMap or Bing maps, currently use Mercator projection.
