A photograph was taen of a building, with the x axis (canera
base) making an angle & with the front-side of the building
(Piz. %1).In restitution the floating mark is to.be moved.in
the coordinate system (%,.3, 2).
The following relations exist between the Two ccordinate
eystens.(x, y,.2).anàd CE,.T7,.2):

From these relationships follow the partial derivatives

Hence, the calculation of x! and y' according to (4.0) with
(4.10) and (4.11) represents a rigorous solution. The conclu-
sion of Section 3 applies implying that the segments can be
chosen arbitrarily large.

4.4.2.1. Consideration of earth's curvature
‘The consideration of earth's curvature is usual on the imag
as well as model coordinates. Correction on model coordi
represents a rigorous solution, while the mene coordina
correction rigorously applies only to near vertical phot
graphs.
According to Pig. 4.2 one obtains for (4.1)
X + X = X

Z = Z + (72 + $2)/2R (left image)

Z = Z + [(Z - p + (F - by) 1/2R (right image)
Thus, the partial derivatives are
