=The curved surface of the earth cannot be shown accurately on a map because such a surface must be stretched or broken in some places as it is flattened. For this reason mapmakers use map projections.=
Map projections provide techniques to properly display features on maps, globes and atlases.
There are many different ways of showing the world on a map, called projections, but none of them are completely accurate.
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.

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
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 makers are called cartographers. There are 3 generally accepted types of map projections. These are cylindrical projections, conic projects and planar projections.
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.
The most common map projections are based on three main geometric shapes: 1) Sphere to a Plane 2) Cylindrical Projections, 3) Conic 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.
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.
Map projections provide techniques to properly display features on maps, globes and atlases.
A projection in geography is a way to represent the Earth's three-dimensional surface on a two-dimensional map. Different map projections distort properties like distance, area, shape, or direction in order to accurately represent the curved surface of the Earth on a flat map. There are many types of map projections, each with its own strengths and weaknesses depending on the purpose of the map.
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 composite map is produced by fitting together a series of different map projections. This technique uses the strengths of each projection to portray the entire globe with minimal distortion across different regions.
