3 main types of map projections
. However map projection refers specifically to a cartographic projection. In addition a number of map projections are based on polyhedra. Other meridians are curves or possibly straight from pole to equator regularly spaced along parallels. There are several types of map projections.Map projections are based on developable surfaces and the three traditional families consist of cylinders cones and planes. The four categories are. Cylindrical projections are distinguished from each other by the north to south stretching denoted by φ. They are used to classify the majority of projections including some that are not analytically geometrically constructed.
Type of projection cylindrical in standard presentation these map regularly spaced meridians to equally spaced vertical lines and parallels to horizontal lines. Planar azimuthal or zenithal projection. The problem is that the surface of the earth is spherical and a map is flat so. The projections stretch from east to west according to their geometric constructions and are the same at any chosen latitude.
They are basically classified into four groups in accordance with the map projection theory or the types of surfaces that are tangent with the globe. Conic in standard presentation conic or conical projections map meridians as straight lines and parallels as arcs. Three major types of map projections. Cylindrical conic plane and interrupted projection.
The study of map projections is the characterization of these distortions. The north to south stretching equals east to west but grows with. Pseudocylindrical in standard presentation these map the central meridian and parallels as straight lines. Many types of map projections are being used for map making.
There is no limit to the number of possible map projections. A cylindrical projection is any projection in which the meridians are mapped to parallel spaced vertical lines and latitudes are mapped to horizontal lines. Each of the main projection types conic cylindrical and planar are illustrated below. Mercator tangential and conic.
Three of these common types of map projections are cylindrical conic and azimuthal.

Projections are a subject of several pure mathematical fields including differential geometry projective geometry and manifolds. I suspect that the three main map projections you have in mind would be.
