A map projection designed on a flat plane touching the globe at one point such as the north or South Pole.
It will be located by the x and y coordinates on a flat plane such as the Cartesian plane.
For maps, it's usually a projection.
an inclined plane

Plane?
A map projection designed on a flat plane touching the globe at one point such as the north or South Pole.
A planar projection map is a map projected onto a plane (flat surface). The details of the globe are a rectangular shaped map that is on a flat surface.
I am assuming that you are in a three dimensional world. Then the three planes of projection would be the xy plane, the xz plane, and the yz plane.
Its called a projection map
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
Using a projection.
To transform degrees to coordinates, you typically need to use a projection system that maps spherical coordinates to a flat plane like a Cartesian coordinate system. One common way to do this is by using a projection such as the Mercator projection for mapping the Earth's surface coordinates to flat map coordinates. Software tools like GIS applications can help with this conversion.

A map projection is a way to represent the curved surface of the Earth on the flat surface of a map.
