InterCommission WG  II/III 
Accomplishments 
The Working Group Activities during the 
past year have centered on preparing the 
program for the period up to the Congress 
in 1996. A Newsletter was distributed in 
March based on the mailing list from 1988- 
92 and as a result of that a revised list has 
been prepared. 
In April 1993a WG business meeting was 
held in Orlando, Florida on the occasion 
of the SPIE International Symposium on 
Optical Engineering and Photonics in 
Aerospace and Remote Sensing which 
included a conference on Integrating 
Photograrnmetric Techniques with Scene 
Analysis and Machine Vision co-chaired 
by Dave McKeown (co-chair of ICWG 
II/IID. see below for more details. The 
discussion at the business meeting started 
on the topic of systems but quickly moved 
on to standards and bench marks for 
digital systems. There was clearly a strong 
feeling that users needed some guidance 
on the performance to be expected from a 
system. It was noted that this was not an 
easy task because of the wide range of 
systems offered, from the Intergraph 
Image Station to the DMS. There was also 
a feeling that such tasks can take a 
528 
considerable amount of time with little 
intellectual satisfaction. 
There was general agreement that the 
terms of reference were broad but 
appropriate and it was the breadth which 
distinguished the working group from 
other more specialist groups, especially 
those working with algorithm 
development. The view was put that the 
group should look to the end user and 
that there was a trend in the USA towards 
the use of orthoimages and that he user 
might well do his own revision using the 
orthoimage. 
The Working Group is considering its 
position on standards and is planning to 
hold a session at the Commission II 
Symposium on the subject. 
Since then the chairperson has had 
discussions with chairmen of other 
working groups about joint meetings and 
collaboration and also discussed the 
possibility of holding a working group 
meeting in South East Asia, with the head 
of the Remote Sensing Centre at the 
Technical University of Malaysia. 
The state of science and technology for 
InterCommission WG IVIII 
There have been a few meetings since 
August 1992 which have included 
sessions on DPWs. The most notable have 
been: 
SPIE "Integrating Photogrammetric 
Techniques with Scene Analysis and 
Machine Vision", in Orlando, U.S.A. This 
meeting stressed the importance of both 
close range and topographic applications 
of digital systems. A review paper by 
Heipke set out the current status of digital 
systems. The conference attracted good 
quality speakers and a large audience and 
good discussion took place between the 
photogrammetric community and the 
machine v:
