Chairman Session 15 Oshima (Japan): May I invite the audience to comment on 
the subject of National Reports. You are aware that any of the 66 Member 
Countries of ISPRS have the right, and I think the obligation, to submit in 
four years interval to any Congress of our International Society for Photo- 
grammetry and Remote Sensing a report supplying information on the state of 
the art and on the development of photogrammetry and remote sensing in that 
country including relevant addresses. They differ indeed in the arrangement 
of contents and are thus difficult to read. In his paper, Prof.Hothmer pre- 
sumes National Reports are hardly ever used and concludes they should be 
abandoned, if this is true. 
Mr. Glendinning (Australia) : My feeling is we should stimulate to improve 
the quality of National Reports to be presented 198^ whilst adopting the 
proposal presented by Hothmer. At the Congress 1984 we then can discuss 
whether it is justified to continue with this undertaking. 
Prof. Badekas (Greece) : My experience so far is that statistical data presented 
in National Reports need better explanations to be clearly understandable. 
Prof. Hildebrandt (FR Germany) : When looking through some National Reports 
I hardly find any information on my particular field, that is remote sensing 
for forestry. You may wish to recommend, therefore, that the various disci- 
lines of remote sensing be better covered. 
President ISPRS Doyle (USA) : Some days ago the Council held a joint meeting 
with all Commission Presidents in Toulouse. The meeting accepted the recommen- 
dations of Hothmer. I will myself invite all ISPRS Members to present National 
Reports at the next Congress 1984 in Rio de Janeiro. 
President Com.VI Hothmer (FR Germany): One objective of the meeting in 
Toulouse was to allocate appropriate session periods to all seven Commissions. 
There will be in total some 125 sessions. The meeting agreed allocating to 
Commission VI two exclusive time periods, thus without any other simultaneous 
session. Whenever you agree that publishing does not make much sense if 
publications are not read, then I think we should devote one of these exclu- 
sive sessions to the basic problem of communication. 
President Com.VI Hothmer (FR Germany) : Another item might be added which is 
related to our assignment of information exchange. I mailed Outline 01.81 to 
the Council ISPRS in January 1981 proposing to devote the last scientific 
session of the Congress Rio de Janeiro 1984 to the topic of TRENDS. The 
reason is that quite a few congressists left the past Congress Hamburg with 
big question marks 3 
+ The Scientist : Is his field of interest not anymore worthwhile to be 
dealt with and should he switch over to, for instance, remote sensing ? 
4 The Educator: What part of his lecture became obsolete, and which 
achievement is indispensable and must consequently be covered from now on 2 
+ The Practitioner : What is the impact of all results of the Congress on 
changing his method and instrumentation ? 
+ The Employee : What is the significance of the Congress for his professional 
Status; will his profession grow or diminish; what updating of knowledge 
can he recommend to colleagues ? 
+ The Manager : Which invention presented at the Congress will become 
operational ? 
The next Congress should endeavour to counteract this negative farewell 
effect attempting to answer these questions.
