Terminology

This chapter describes technical terms related to data management.
A measured point consists of three coordinate components - two horizontal components and
one vertical component. The generic term for the three coordinate components is coordinate
triplet.
Depending on the class, a point ID can contain more than one coordinate triplet of the same
and/or of different classes.
The class describes the type of coordinate triplet.
