Glossary
Straight line between two points. Its end point is identical with the beginning
of a curve or spiral. The tangent is perpendicular to the radius of the curve.
The sub class describes certain classes in detail. It indicates the status of the
position when a coordinate triplet was measured and how the coordinates
were determined.

A transformation is the process of converting coordinates from one geodetic
datum to another.
Requirements
Transformation parameters.
