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.

A map projection designed on a flat plane touching the globe at one point such as the north or South Pole.
Orthographic projection consists of several key components: the projection plane, the object being represented, and the projection lines. The projection plane is an imaginary flat surface onto which the object's features are projected. The object itself is viewed from multiple angles, typically the front, top, and side, allowing for a comprehensive representation. Finally, the projection lines are perpendicular to the projection plane, ensuring accurate depiction of the object's dimensions and relationships without distortion.
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.
