The three main types of map projections: are azimuthal projections, conformal projections, and equal-area projections. The azimuthal projection preserves the direction from the center of the map and the distance to that center. It is used in mapping out earthquakes and flights from and to certain airports. Conformal projection is a type of projection that preserves angles locally. Maps created using conformal projection are used in sea and air navigation and weather forecast. The Mercator projection is a projection that is widely used, but the relative size and shape of some features are distorted. This type of projection is good for the mapping of small areas. Scale is the ratio of the distance between two points on a map to their actual distance on the Earth's surface. When creating a map projection, selecting the right type of projection depends on what the map will be used for and we reviewed these visuals.
