subview-window with a higher resolution. Any geometric
operations, especially the measuring of control points for
the picture orientation, can be done (Fig. 3.3.2). Parts of
the image can be digitized also and displayed in the
overview-window for partial operations.

The creation of orthophotos is possible in a test-mode.
Parts of the image can be done with different
transformations and resampling functions to control the
result. The hierarchical plan structure is dispalyed with all
control points in the image of the overview-window. For
the test-mode groups or single regions of the facade can
be selected. With choise of different functions a testing is
possible. The result is displayed in a third window as an
orthoview. Forfasttesting a low resolution of the projection
plane must be selected to reduce the counts of the pixel
transformations. But for the resampling functions by the
indirect transformation, it is nesseray to have access on
the original image with the full resolution (low level) in the
pyramide structure. Only in this way it is possible to get
images with clear edge structure.
It has been shown, that the execution for transforming
different plane fagade areas in interactive mode can be
done in adequate short time. A definitive fixation of the
transformation attributes for all partial planes is acquired
during a test-mode. The object orientated transmission
of plane attributes takes place in the plane hierarchy. The
transformation attributes of the upgraded planes are
inherited to the downgraded ones, if no attributes are
defined for them. All fixations are registered in a control
file for the separate generation of orthophoto plans.
