For coordinate systems with source RTCM, only the geoid model in use can be
changed.
However, if no projection is received with the automatic coordinate system,
then the projection can also be defined.
In Coordinate Systems, highlight a coordinate system. A copy of this coordi-
nate system is taken for further configurations. Press New or Edit.

Description
A unique name for the new coordinate
system. The name can be up to 16 char-
acters long and include spaces.
Available for transformations with control
points. Manually entered transformations
do not have control points. The method
by which residuals are distributed
throughout the transformation area. The
transformation results become more real-
istic and any strain is dispersed in the
transformation.
Distribute the residuals of the control
points according to the distance between
each control point and the newly trans-
formed point.
Distributes the residuals using a multi-
quadratic interpolation approach.
The type of transformation.
Available when editing a coordinate sys-
tem and for Twostep transformations.
The name of a preliminary 3D transfor-
mation, which, together with the selec-
ted projection, is used to obtain prelimi-
nary grid coordinates for a final 2D trans-
formation.
