The most common map projections are based on three main geometric shapes: 1) Sphere to a Plane 2) Cylindrical Projections, 3) Conic Projections.
they are cylindrical, azimuthal, and conic.

Map makers are called cartographers. There are 3 generally accepted types of map projections. These are cylindrical projections, conic projects and planar projections.

The three main types of map projections are cylindrical, conic, and azimuthal. Cylindrical projections show the Earth's surface on a cylinder, conic projections project the Earth's surface onto a cone, and azimuthal projections project the Earth's surface onto a plane. Each type has variations that can result in different map distortions.
Map projections are important because they allow us to represent the three-dimensional Earth on a two-dimensional map. Different projections are useful for different purposes, such as preserving accurate distances, areas, or shapes. Choosing the right projection ensures that the map effectively communicates information without distorting important geographical features.
Map projections are mainly derived by mathematical formulas that project the Earth's three-dimensional surface onto a two-dimensional plane. These formulas determine how geographic features like shape, scale, distance, and direction are distorted on the map. Different projections are suited for different purposes depending on the type of distortion that is most acceptable for a particular map.

A map projection simply is a representation of the round, 3D surface of the earth onto a flat, 2D map. There are different map projections such as Mercator and Robinson each of which have advantages and disadvantages.The appropriate projection for a map depends on the scale of the map and the purposes for which it will be used. For example, a Mercator projection has straight rhumb lines and is therefore excellent for navigation, because compass courses are easy to determine, but there is distortion near the poles.
