Shift, Rotate & Scale
methods
Description
Matching points
Applies shifts and/or rotation and/or scale to
one or several known points. The shifts
and/or rotation and/or scale are calculated
from selected points using a 2D Helmert
transformation.
Elements that must be known are
•
the coordinates of at least two matching
points for the calculation of the shifts
and/or rotation and/or scale.
•
the coordinates of the points to be shif-
ted, rotated and/or scaled. They must be
stored in the job.
Points with full coordinate triplets, position
only points and height only points can be
used.
The number of pairs of points matched
determines whether the shift, rotation and
scale values are computed. For only one
point, only shifts are calculated, rotation and
scale are not.
