A map projection method
is a conversion describing the mapping from a mathematical earth model
(spheroid like a sphere or ellipsoid) to the plane.
It is not possible to map from a curved surface like a sphere or ellipsoid to a plane
There are a lot of different map projection methods known. In literature, more than
200 methods are
There are different possibilities for describing the properties and characteristics
of map projections.
- mathematical or geometrical properties:
- applying map projection methods for
specific purposes (e.g. area of usage (dimension, position
on the earth, shape of the region...):
- choosing the optimized map projection
parameters covering the needs best
