Within the fields of the history of culture increased applications of advanced measuring techniques, e.g. photogrammetry, have clearly demonstrated the difficulties of communication between various scientific branches. The demands of measuring technicians for precise instructions have been very difficult to satisfy. We have partly landed up in a new situation of scientific work where the lack of adequate education and experience prohibits proper utilization of existing technical innovations. Presentation of applications and problems regarding instruments, treatment of mechanical equipment and so on, are not - in our opinion - meaningful to a wider public until the general background of the documentation has been accounted for in greater detail - practically as well as theoretically. These circumstances have called for a serious examination of the very base of data production regarding the relevance of data as well as the problem of education in order to make it easier for the two blocs - measuring techniques and history of culture - to understand each other. -- CAL
