with great fidelity and precision in either an analogue
(pictorial) way or in digital form. We have marvelous new ground
techniques based on the recording of satellite signals, and
others that use inertial sensors, to determine coordinates of
discrete terrain points. Above all, scientists in other fields
provide us every year with new, more powerful and more efficient
computers and other instruments for processing, storing and
displaying survey data in almost any desirable form.
As a consequence one would expect that the scientific and
professional leaders in our field would grasp these new
possibilities and try to develope new operational concepts that
would permit us to use the new techniques efficiently and in
accordance with the pressing needs of contemporary society. In
reality, the opposite is true. Our distinguished professors and
researchers dwell mostly on single techniques, seldom asking
meaningful questions concerning the merits of alternative
solutions. Usually (obviously there are prominent exceptions)
their inquisitive minds do not enter broader fields of
application. They prefer not to confront the simple question,
"why”. As a matter of fact, some of them consider knowledge of
operational details as a detraction from their "scientific aura".
They follow the safe ancient maxim: "Si tacuises philosophus
mansisses" and thus reduce themselves to rather narrow
technicians, mostly in the computational field. During my
frequent visits to universities on all continents I have
discovered that some of my colleagues, professors of
photogrammetry, know little (occasionally nothing) of such an
important technique as orthophotography. They have never heard
about the possibilities of stereo-orthophotography, they have
only vague ideas about field surveying, they know equally little
about modern photography and cameras, and they are convinced that
basic surveying and mapping operations such as the cadastre
belong in the field of law.
I must say that this situation is partly due to the fact
that many countries of the world, among them such a leading
country as the United States, do not recognize geodetic
disciplines (geodesy, surveying, photogrammetry, cartography,
remote sensing) as being worth the support of a full-fledged
university department. Instead, they provide "extension courses”
or "post-graduate curricula" which supposedly should be capable
of converting all kinds of forestry or architecture students into
competent experts in surveying and mapping. To add insult to
injury, these substitute measures are usually part of civil
engineering departments, which for many years have been
recognized as the "dead hand" on geodetic disciplines. I never
could understand what the science of building bridges or
skyscrapers had in common with geodetic disciplines. As I see
it, geodesy and the related disciplines belong to applied
physics. If for practical or iocal reasons they cannot- be part
