Mercator Projection : longitude and latitude as straight, parallel lines
Conic Projection : a circular map made from a flattened cone, centered on a pole or other point
Gall-Peters Projection : relocates standard parallels, narrows longitudinal spacing
Robinson Projection : approximates a true spherical view of the Earth, except the poles
Winkel Tripel Projection : an azimuth approximation of the world view, similar to Robinson
The most widely used is the Mercator projection, the major disadvantage being its area expansions (areas closer to the poles appear larger and lack their true shapes). The Gall-Peters Projection provides a closer approximation of the relative areas. All flat representations of a spherical surface will create variances in "true" size or shape.

A map projection is a flat representation of the Earth's global surface. There are for different types of projections-- those that focus on distance, those that focus on direction, those that focus on area, and those that focus on shape. Conformal map projections are the type that show the correct size of continents but distort area size.
Map projections provide techniques to properly display features on maps, globes and atlases.
The other popular map projections include the so-called "compromise" projections, including: Robinson Winkel Tripel Dymaxion (Buckminster Fuller) Butterfly Map (Cahill) Kavrayskiy Wagner pseudocylindrical Chamberlin trimetric Fine's cordiform
Map makers are called cartographers. There are 3 generally accepted types of map projections. These are cylindrical projections, conic projects and planar projections.
Polar,Robinson,interupted,mecartor
The most common map projections are based on three main geometric shapes: 1) Sphere to a Plane 2) Cylindrical Projections, 3) Conic 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.

Equal-area map projections, such as the Mollweide or Gall-Peters projections, are best for comparing the sizes of countries as they accurately represent the relative sizes of land masses. This helps to avoid distortions that can occur in other types of map projections, such as the Mercator projection.
World maps come in a number of projections, each have their own uses and problems. These different projections include a globe, several types of Mercator projections, Robinson, Miller cylindrical, stereographic, orthographic, Sinusoidal, Gnomonic, several types of Azimuthal projections, and others. The US Geological Survey has comprehensive information on map projections available.

Conic map projections are created by projecting the Earth's curved surface onto a cone. The cone is then unwrapped to create a flat map. This projection method is useful for representing mid-latitude regions with less distortion compared to other types of map projections.
Some ways to manipulate map projections include changing the center of the map, adjusting the scale or zoom level, rotating the map orientation, and selecting different projection types such as Mercator, Robinson, or Peters. These manipulations can help tailor the representation of geographic data to better suit specific needs or highlight certain features on a map.
