TRANSDAT Geosoftware executes coordinate transformations and geodetic
datum shifts between many coordinate and reference systems of America,
Australasia, Europe, Germany special and world-wide, at high precision
and high speed.
Navigation maps are printed with a coordinate grid that is a
two-dimensional projection of the three-dimensional Earth surface, based
on a given Coordinate System. Historically the countries over the world
use many different coordinate systems. Earth is shaped not like a
sphere; it is a geoid that has no exact mathematical definition and
whose form can be at best approximated by an ellipsoid. To make an exact
projection of a region into a coordinate system, the region is first
projected onto a so-called reference ellipsoid that would fit the region
best. The reference ellipsoid is mathematically defined and can be used
for a coordinate system projection. Historically countries all over the
world developed and used different and often more than one local and
global Reference Systems.
