be presented for lack of time. 
Thursday, July 15, 1976, from 15.45 to 17.15 
Session 4 of Commission II 
Topic: Analogical Instrumentations 
Chairman: Dr. A. J. van der Weele (Netherlands) 
Invited Papers 
Author: Mr. H. C. Zorn (Netherlands) 
Title: The Development of Analogue In- 
struments /P 11/08 
Mr. Zorn stressed that his report was supposed 
to be a comprehensive review of all the new 
analogue instruments. But the completeness of 
the information to be contained in the report 
depended greatly on the collaboration of the 
manufacturing companies, which unfortunately 
had not always been readily available. Conse- 
quently, the report was lacking in many places. 
Author: Dr. B. Makarovic (Netherlands) 
Title: Trends in the Development of Com- 
puter Supported Analogue Instru- 
ments /P ///07 
Mr. E. Greer (South Africa) mentioned a system 
with feedback from computer to an analogue 
instrument for profile measuring. 
Presented Papers 
Author: Dr. E. Dorrer (F.R.G.) 
Title: Software Aspects in Computer- 
Assisted Stereoplotting PP ///07 
After considering three different combinations 
of calculators for assisting stereoplotters, i.e., 
desk, mini and terminal, Dr. Dorrer spoke more 
about the application of the first one. Dr. J. Trinder 
(Australia) asked about the speed of registration 
when using a desk calculator. Dr. Dorrer 
answered that it is possible to record 3 to 5 
points per second. 
Author: Mr. G. E. Bormann (Switzerland) 
Title: Features and Design Parameters 
of the Wild Aviomap System PP 11/02 
Author: Mr. H. Schéler (G.D.R.) 
Title: Some Comments on the Comparison 
of Instrument Parameters of Stereo- 
plotters PP ///45 
Mr. Schéler presented three instruments by 
Zeiss Jena, namely, the Topoflex, Topocart and 
Stereometrograph, and gave for each of them 
their field of application. 
Author: Dr. R. Schwebel (F.R.G.) 
Title: The New Photogrammetric Data 
Acquisition and Transfer System 
ECOMAT 12 PP 11/50 
In his presentation Dr. Schwebel observed that 
the three instruments of Carl Zeiss, Planimat, 
Planicart and Planitop, cover all the requirements 
of photogrammetric work.

The chairman regretted that there was no more 
time for the presentation of the following two 
Presented Papers that had been announced: 
"The Galileo Stereosimplex G6” by Dr. W. G. Ferri 
(Italy) PP 11/08 and The Stereo Facet Plotter” by 
Mr. H. Yzerman (Switzerland).

Session 5 of Commission II 
Topic: Automation in Photogrammetry 
Chairmen: Mr. G. Ducher (France) 
Dr. G. Inghilleri (Italy) 
These two consecutive sessions on automation 
in photogrammetry were held jointly with Com- 
mission IV and are reported under that Commis- 
sion. 
Monday, July 19, 1976, from 14.00 to 15.30 
and from 15.45 to 17.15 
Session 6 of Commission ll 
Panel Discussion between Builders and 
Users of Photogrammetric Instruments 
Topics: 
1. Is the current equipment adequate for training 
in photogrammetry at the various levels? 
2. Should there not be a greater effort towards 
standardizing photogrammetric equipment? 
3. Should more emphasis be given to developing 
equipment for non-conventional applications? 
4. Should more of the equipment be capable of 
correcting for model deformation? 
5. Should emphasis be given to equipment that 
directly generates information? 
6.Is the current photogrammetric equipment 
adequate for map revision? 
Chairman, Lecturer and 
Moderator: Dr. S. G. Gamble (Canada) 
Co-Chairman: Mr. K. Rainesalo (Finland) 
Panelists representing users: 
Dr. H. G. Jerie (Netherlands) 
Dr. G. Inghilleri (Italy) 
Dr. H. M. Karara (U.S.A.) 
Mr. P. Mott (U.K.) 
Dr. S. K. Ghosh (U.S.A.) 
Mr. G. Ducher (France) 
Panelists representing manufacturers: 
Mr. G. E. Bormann (Switzerland) 
Dr. H.-K. Meier (F.R.G) 
Mr. J. O. Danko (U.S.A.) 
Mr. H. Busch (France) 
Mr. J. Klaver (Switzerland) 
The chairman announced that the procedure 
to be followed would be to deal with each of 
the six questions listed above with one panelist 
representing users and one representing builders. 
The co-chairman dealt with the question con- 
cerning the establishment of a special category 
within the I.S.P. for sustaining members. 
Panelists Dr. Jerie (users) and Dr. Bormann 
(builders) discussed the first question, concerning
