Thus, the inclination of each model in relation to the
horizon will be:
i
A (pi = 5
1
A (p
n
SA (p
n
)
and the ordinates of the correction polygon
i / BxM
h = S j A(f)i x
* +1 1 \ 1000x6366
with b 1 =o. B is the base of the model and M the denominator of the scale.
However, the following expression was programmed
i
h =S (A (p i x B x 2618 x 10~ 6 )
¿+1 i
Which corresponds to M = , since the programme is envolving a very big
6
work in which that scale was adopted to the models during the triangulation.
Nevertheless, it is the intention of the ARTOP to modify this part of the programme,
introducing the scale of the first model, determined as indicated in 2.2.
The base B is obtained by difference between the coordinates of the central pass
points, limit of the model.
After, and for correction effects, another polygon is considered, resulting from the
first by linear smoothing in two iterations.
If later statoscope data are introduced the polygon to transform will be
Hi = hi + bzi (est.)
where the bzi values are referred to the height of the second camera of the strips.
2.2 — PLANXMETRIC ADJUSTMENT
2.2.1 — STRIPS WITHOUT INTERMEDIARY CONTROL POINTS
For the planimetric adjustment when there are no intermediary controls, the
expressions deducted by Vermeir are adopted to the determination of the correc
tions X, Y, azimuth and scale in each model.
