Coordinate Systems in MobileMapper Office

In MobileMapper Office, the definition of a coordinate sys-
tem can be split into two different sets of parameters: hori-
zontal system and height system.
The horizontal system may be one of two types:
- Geodetic type: the system relies on the definition of a 

datum. A datum is an ellipsoid with possible linear and 
angular shifts

- Grid type: the system relies on the definition of a datum 

and a projection

The height system may be one of two types:
- Ellipsoid elevations: All elevations are calculated from 

the datum defined in the coordinate system used

- Orthometric elevations: All elevations are calculated 

from the available geoid model (EGM96 Worldwide 
Geoid model)

A large number of geodetic and grid systems are available 
for use. However, if none of these systems is suitable for 
your jobs, you can create a new one, based on the informa-
tion you have to define this system. This is described on page 
109.
