ABSTRACT:

 

Automation, in its broadest sense, means the reduction to the possible minimum of two main factors, the time required for performing an operation and the operator interference with the machine. The accomplishment of these two factors needs tremendous amount of information and/or knowledge of different fields, i.e. automation needs different types of information from different fields in order to be carried out properly. Thus it can be said that integration is a necessary step towards automation in mapping. Based on this, scientists and researchers need to pay attention to what has been accomplished in other disciplines related to their fields in order to increase their scope of knowledge and to determine the best approach of solving existing problems in their specialties. Else, automation will always suffer from severe deficiencies and will never achieve its goals. In this paper, digital photogrammetry (DP), remote sensing (RS), and geographic information systems (GIS) discussed from the point of view of integration. The level of contribution of each field and the flow of operations pertinent to the three fields are outlined. Different forms of possible integration are presented.
