Select an existing coordinate system and press
OK
.
All the following steps are identical with the determination of a new coordinate
system from the
Matched Points (n)
panel onwards. Refer to "39.3.2 Deter-
mining a New Coordinate System"

Matching Points: Selecting/ Editing a Pair of Matching Points
Before calculating a transformation, it must be defined which points in
Job
where WGS84 points are stored
and
Job where local points are stored
are to be matched. Pairs of matched points are displayed in one line in
Matched Points (n)
. New pairs of matched points can be created, existing
pairs of matched points can be edited and pairs of matched points can be
deleted.
