The web mercator projection
WebMercator projection. The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer, Gerardus Mercator, in 1569. This map projection is practical for nautical applications due to its ability to represent lines of constant course, known as rhumb lines, as straight segments that conserve the angles ... WebFor a projection such as Web Mercator, the closer toward the poles you go, the smaller area you can analyze with the same distance distortion. To understand the specific differences in distance measurements between geodesic and planar, use the Measure tool to measure the distance between two locations in Planar mode and in Geodesic mode.
