Nov 21, 2017 · A map projection is a technique for taking the curved surface of the earth and showing it on something flat, similar to a PC screen or a bit of paper. maps makers have conceived techniques for taking points on the curved surface of the earth and “anticipating” them onto a flat surface.
Map projection definition: a means of representing or a representation of the globe or celestial sphere or part of it on a flat map, using a grid of lines of latitude and longitude. See examples of MAP PROJECTION used in a sentence.
What is Map Projection? Map Projection is a critical aspect of the Geographic Information System (GIS) and Cartography. Put simply, map projections aim to turn the 3-dimensional globe, i.e., the Earth, into a 2-dimensional plane, i.e., a map. Each and every map we use, from Google Maps to in-car GPS, uses some form of a projection to represent ...

A map projection is used to portray all or part of the round Earth on a flat surface. This cannot be done without some distortion. Every projection has its own set of advantages and disadvantages. There is no "best" projection. The mapmaker must select the one best suited to the needs, reducing distortion of the most important features.
Oct 12, 2018 · A map projection is a method to flatten an earth’s surface into a plane to make a geographical map. It requires a systematic transformation of the latitudes and longitudes of locations from the globe’s surface into locations on a plane. All projections of a sphere on a plane distort the planet’s surface somehow and to some extent.
