3.8. Instrumentation for Training 
(Commission II/IV Newsletter; editor: Prof Dr Ian Dowman, 
UK) 
This useful, successful series was continued in September 1988 
and October 1989 with Newsletters No. 3 and 6, respectively. 
According to them, the following instruments, computers and 
software systems are used for training in photogrammetry 
and remote sensing: 
- Simple stereoplotters such as the CP 1 
- Photogrammetric stereoplotters no longer used for map 
production, e.g. A7, B8, PG2 and others 
- Simple analytical compilation systems such as SAPS or 
analytical plotters such as Planicomp 
- Software packages for computerized image processing 
Conclusions 
Space technology, microelectronics, computers and information 
handling are progressing rapidly. These disciplines have a 
great and direct influence on photogrammetry and remote 
sensing. 
Research institutes and the industry are making use of the 
chances resulting therefrom: they offer ever new solutions 
year after year for tasks in all areas of photogrammetry and 
remote sensing, so that state-of-the-art, automated instrumenta 
tion is on the market worldwide. On the other hand, thousands of 
companies and offices engaged in map-making are still equipped 
with conventional, i.e. optical-mechanical equipment, which is 
known to have a service life of 20 to 30 years. 
Introduction into practice of the advanced systems, with 
increasing shares of computers and software, will certainly 
be a step-by-step process, but as they substitute the 
conventional equipment, another increase in efficiency is 
certain to come. 
The Working Groups of Commission II of the ISPRS concentrate 
their efforts on the further improvement of systems for data
