Attempt a systematic classification of map projection
Answers
Projection of maps is systematic classification of latitudes and longitudes of various locations from surface of any shape.
Maps can't be made without projections.
All map projections distort surface in some fashion.
Depending on purpose of map some distortions are taken and others aren't different to map projections.
There is unlimited number of map projections.
Generally surfaces of planetary bodies can be mapped even if they are irregular to be modeled with sphere/ ellipsoid.
Projections are subject of several mathematical fields which includes differential geometry and projective geometry.
"Map Projection" refers to a cartographic projection.
In a systematic map projection, the latitude and longitude is systematically transformed from the spherical surface into the locations on the plane.
Without map projection, one cannot create the map through the map is somewhat distorted when placed on a flight.
The gradients are necessary for projection of the map and one need to take care of the area, direction, shape, distance, bearing and scale.
