Cartesian plane
Because it's plotted on a flat background
mercator
First, a coordinate. A coordinate is a number. It labels a point on a line.Second, a coordinate axis is a line with coordinates.to label a point in a plane (a flat surface), we need more than one coordinate axis, and we place a second at right angles to the first.Those axes are called rectangular coordinate axes, because they are at right angles to one another. The coordinates on them are called rectangular coordinates. They are also called Cartesian coordinates.
Its base is a flat surface
