INSTRUMENTATION FOR DATA REDUCTION AND ANALYSIS 
REPORT ON THE ACTIVITIES OF ISPRS COMMISSION II, 1980 - 1984

Commission II 
ORGANIZATION AND OBJECTIVES 
The major part of the activities of Commission II is conducted through five 
Working Groups. All of these were reorganized or established by the beginning 
of 1981, according to the recommendations and resolutions of the Hamburg 
Congress. At the same time the terms of reference of each Working Group and 
the corresponding topics of studies were defined. 
The areas of activities of the Working Groups are reflected in their names. 
Working Group II/1 on "Analytical and Hybrid Instruments" and Working Group 
II/2 on "Automatic Equipment and Systems" are concerned with photogrammetric 
instrumentation. The remaining three Working Groups are concerned with the 
instrumentation for processing and analysis of remotely sensed data. They 
are: Working Group II/3 on "Instruments for Analysis of Remotely Sensed Data"; 
Working Group II/4 on "Instruments for Preprocessing, Storage and 
Dissemination of Remotely Sensed Data"; and Working Group II/5 on "Equipment 
for Processing Synthetic Aperture Radar Data", 
In addition to the five working groups an Instrument Manufacturer's Group was 
established in 1981. The membership of this group is composed of 
representatives of instrument manufacturing companies to Commission II. These 
members communicate directly with the Commission president and secretary. 
The general objectives of Commission II are: the conduct of theoretical and 
feasibility studies in support of innovations and advancements in the design 
of instruments and systems for processing and analysis of data; the conduct of 
studies related to the analysis, testing and evaluation of existing 
instruments and systems; and the dissemination of information on studies and 
research activities performed by the members of Working Groups and other 
colaborators of Commission II. 
In the area of theoretical formulations and feasibility studies the emphasis 
is on the new concepts and the new technologies for their implementation. 
Despite the fact that the processing and analysis of photogrammetric and 
remotely sensed data cannot be neatly separated into hardware, algorithms, 
software and other sub-entities, all the Working Groups have endeavored not to 
concentrate on specific algorithms except in cases where they affect directly 
the system design or require generic instrument development. 
In the area of studies related to the analysis and testing of existing 
instrumentation the main. concern was the development of standard procedures 
for testing of instruments and systems, and the establishment of criteria, 
guidelines and procedures for evaluation of prototypes and commercially 
available instruments. To this area of activities belong also the attempts to 
develop procedures for the determination of optimal configuration of hardware 
components and optimal organization of software for large data processing and 
analysis systems. 
In the area of the Commission's activities concerned with the dissemination of 
information on the results of studies and research work it has been felt that 
the presentation of papers and reports at the inter-congress Symposia and at
