Overview
A coordinate system
•
consists of up to five elements.
•
allows the conversion from WGS 1984 geodetic or cartesian coordinates to, local carte-
sian, geodetic or grid coordinates and back.
•
can be attached to jobs.
•
can be manually defined.
•
can be computed in the field.
•
can be directly received from a reference network. Refer to "22.3.4 Configuration of a
Rover Real-Time Interface".
•
can be downloaded to LGO.
•
can be uploaded from LGO.
All GPS surveyed points are always stored as WGS 1984 geodetic coordinates regardless
of the coordinate system being used. Using a different coordinate system converts the coor-
dinates displayed on the screen, but does not convert and restore the coordinate values in
the database DB-X.
One coordinate system can be attached to a job at one time. This coordinate system remains
attached to the job unless it is changed.
