It is not possible to map from a curved surface
like a sphere or ellipsoid to a plane without distortion.
There are different possibilities for describing
the properties and characteristics of map projections.
-
mathematical or geometrical properties:
- extrinsics
(e.g. shape and aspect of the mapping surface)
- intrinsics
(e.g. distortion behaviour as conformity, equal area
condition, equidistant lines ...)
- 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
