However, a future-oriented software system for photogrammetry and carto-
graphy must not only provide a comprehensive range of functions but also
user-friendly and easy handling. These apparently contradictory demands
are detailed in Fig. 1.

Fig. 1: Performance and Handling Demands on Modern Software
The demands for a comprehensive range of functions and easy handling are of
particular significance if a software product is to be accepted and used all
over the world by users with different backgrounds. The tuition concept of
the PHOCUS software system developed by Carl Zeiss, West Ger-many, is used
to illustrate how the handling of complex application soft-ware can be learnt
quickly and efficiently in an operator-friendly environment.
