such an instrument can allow latest research conclusions.
The amortisation quota of the big instruments and the costs of
operating time for highly qualified staff lead to plotting
costs which can practically not be forseen in the case of
mass-examination by photogrammetry in the preservation of
monuments (e.g. shape-studies at a large number of objects
regarding the proportions, construction-elements etc.). These
investigations though would be very important for research
work and the practice of conservation of cultural heritage.
Such a small plotter could also be used as an ideal training-
instrument. Often the training is effected by using instruments
on which not even sketchy, usable plots are possible. A small
emergency-plotter can produce very important, sometimes urgent-
ly needed restitutions and represents at the same time a very
flexible training instrument. The fact that it is transpor-
table and its price predestinate its double-function.
Economical and technical limits are set for the development of
a small hardly disadjustable, eventually independant from the
current-line, cheap transportable analoguous instrument. Such
an analytic plotter can fulfill the user's wishes but can
certainly not offer all qualities of a bigger, all-round ana-
lytical plotter.
Nethertheless Zeiss Oberkochen was the first firm able to find
a reasonable compromise with its mini-plotter (a further deve-
loped stereo-plotter).
By means of a calculator, short connecting lines between the
actual measurement points are set within sensible time-incre-
ment and there where it is necessary to work with shorter dis-
tances between the measurement points. With the additional use
of a small calculator, a line-voltage stability equipment, an
emergency generating set, plotters of different sizes, an
emergency dark room equipment, folding tables and seats, a
flexible terrestrial camera equipment combination of instru-
ments offers more than analoguous instruments such as e.g. the
choice of the plan of reference for the plotting after the
recording in case of catastrophy a valuable plotting restitu-
tion of the recorded objects with arbitrary angle of inclina-
