The amount of different types and variations of
map projections is nowadays grown up to more than 200. They vary in
properties and usage:
- for the
display of topographic data maily conformal projections are
thematic and statistical data very often equivalent
projections are used, or also equidistant.
navigation, conformal projections are used. A very
often used projection therefor is/was the Mercator projection which
also is keeping the lines of same azimuth (loxodrom) as straight
- For very
small scale maps in publications and for wall maps, often also
composed projections are used.
An overview of popular map projections is given
in the following table. The main classification is done based on
their deformation properties, and their mapping surface. Their main
use is given.
