Also, the development going on within photogrammetric
industry are interesting. Recently, some of the
manufacturers that until now have been known Primarily as
hardware producers have announced products where the
companies only make the software, basing the system
otherwise on standard computer workstations. These can be
interpreted as a symptom of the trend in which
photogrammetry is increasingly based on the use of digital
techniques. Obviously, it is important that efficient tools
and techniques are used for the product development - for
the software development.
For software production organisations it might be easier to
adopt internal standards about tools and techniques,
Opposite to academic and research oriented organisations.
In production organisations the benefits are more obvious,
very often they can be interpreted in economical terms.
Perhaps also the continuity of such efforts can be
guaranteed more easily. But also within the academics there
is need for standard tools for software to be used for
photogrammetry. Taken education, it would be beneficial to
have a standard language or language extension where we
could directly use for photogrammetry typical data types
and operations. The existence of such a tool would make the
experimentations easier because it would be possible to
concentrate on the problem at hand, without worrying about
the underlying technical details. Also information exchange
would benefit of a commonly used high level notation.
