1. The XVI. Congress of the International Society for Photogrammetry and 
Remote Sensing in Kyoto 1988 accepted resolution II-2 (WG II/2 on 
"Photogrammetric digital image processing systems") saying: 
The Congress 
Noting the contents of the Working Group II/2 technical 
sessions at this Congress and that during 1984-1988 the 
Working Group II/2 has successfully carried out 
research, disseminated the results and contributed to 
promotion in the area and further noting that the 
progress in the area of digital systems is very rapid 
and substantial 
Recognizing that the need for development and evaluation of systems, 
and dissemination of knowledge is increasing 
Recommends that the activities of the Working Group II/2 be 
continued under the same name and terms of reference. 
and resolution III-4 (Algorithmic aspects of digital photogrammetric 
workstations) saying: 
The Congress 
Noting that digital data is becoming increasingly available and 
high performance hardware components are offered at 
reasonable cost to support processing of this data 
Recognizing the need for developing and expanding fully digital 
systems including on-line triangulation, interactive 
treatment of digital terrain models, and image analysis 
techniques 
Recommends the study of algorithmic aspects to support objects 
feature extraction and location on digital photogramme 
tric workstations.
