as proposed by Prof. John Dewey, the Canadian delegate. A proposal was made that the 21 st Congress be held in USSR, and the 22nd be in the USA. The Final Banquet was held at Chilford Barn Hall with many old friends, former National Delegates, and Congress Program Chairman attending. Among the honored guests were Geoffrey Courtney-Pratt, George Lunn, William Hyzer, Carlos Elmer and Robert Shoberg, accompanied by their wives. The Schardin Award was presented to Gary L. Stradling, Los Alamos Laboratories, Los Alamos, New Mexico. The Photosonics Award was presented to Gary R. Hough, LTV Missiles and Electronics Group, Dallas, Texas. The award was given to him in recognition of his efforts to advance the studies of submicrosecond phenomena using halographic technology. This technique aids in investigations and research in aeroballistics, high energy collision mechanics, and particle physics. L.L. Endelman, San Jose-USA.
13th International Symposium on Architectural Photogrammetry October 23rd-26th, 1990, Cracow Poland The symposium took place in the large session room of the senate of the Cracow University of Mining and Metallurgy. The former rectors looked down at us, lending an atmosphere of respect and academic dignity. The opening speeches were appropriate, not endless, never without sense. Dr. Jachimski, President of the Polish Society of Photogrammetry and Remote Sensing, and Professor Sitek, the co-organizer welcomed us to this symposium which took as its theme "the application of numerical photogrammetry and remote sensing and spatial information systems for the conversion of architectural and urban heritage and for archaeology." The co-founder and honorary member ofCIPA, Maurice Carbonnell, set the scene. He discussed the past, present and future of architectural photogrammetry. Other speakers were Prof. Borusievics of the Polish Academy of Sciences and the Dean of the Faculty of Mining Geodesy, Prof. Czja. From the very beginning and right up to the end of the symposium, the resolutions committee had to keep a watch for good proposals, future-oriented ideas, and problems to be solved. As always, many of the papers dealt with practical applications for frequently recurring problems; how to solve the problems, and how to achieve this economically and efficiently. L. Mauelshagen, Bochum/Germany, reported for colleagues about stone wall restoration using multi-spectral photography. M. Stephani, Munich/Germany, spoke about raster shading visualization from which gross errors could be detected immediately. However, for the output a proper photoraster plotter would be necessary. P. Grimaldi, Bari/Italy, was quite enthusiastic about the new possibilities offered by the exact photogrammetric restitution of churches and other sacred buildings. J.P. Saint-Aubin, Paris/France, presented a paper on a computer program which uses a combination of vector and raster modes for the presentation of architecture. Using this classification and analysis of details and characteristic elements proved to be much easier. E. Wanot, Warsaw/Poland, showed wonderful pictures and photogrammetric restitutions of a Buddhist monastery stemming from cooperation with colleagues in Ulan Bator, Mongolia. A. Almagro Gorbea, Granada/Spain, using the Vienna bundle adjustment programme, ORIENT, gave an interesting report on a very difficult restitution of an old Roman sundial. R.W.A. Dallas, York/UK., always a fighter for renovation of CIPA, explained the very detailed specifications for the application of photogrammetry for architecture and archaeology in the United Kingdom. U.V. Vainauskas, Vilnius/Lithuania, recommended combinations of aerial and terrestrial photography for architecture and archaeology. G. Eckstein, Stuttgart/Germany, drew attention to the co-operation of photogrammetrists and experts in architecture, archaeology and

other fields during the process of restitution and he found that the new twin binoculars should be used more and more. R. Zuntopp, Bonn/Germany, reported that he used aerial photography systematically for archaeological surveys in order to protect those sites at risk. L. Ferreira da Silva and S. Gomes, Rio/Brazil, informed us about the renovation of the famous Corcovado monument of Jesus Christ, the landmark of Rio de Janeiro. R. Waldhiisl, Vienna/Austria and J. Peipe, Munich/Germany, presented an invited paper on control information (minimum and optimum) for terrestrial photogrammetry, especially for architectural photogrammetry and for two- and three-dimensional objects. The different kinds of control information were treated systematically. St. Bajer and colleagues, Slupsk/Poland, asked for simpler methods, both for photography and restitution, in the fields of architectural photogrammetry. Non-metric cameras have to be used if the great number of objects that exist are to be documented in photogrammetric archives properly and in time. F. Seleskovic, Sarajevo/Yugoslavia, worked on a big monument and helped to transfer the dimensions from its model to the field site. J. Badekas, Athens/ Greece, made an orthophoto plan of an old ship found underwater in the sea. Thus, he was the only one this time who reported on practical use of underwater photogrammetry. J. Jachimsky, Cracow/Poland, the organizer of the symposium, helped to reconstruct the wall paintings in a cupola by means of orthophotographic developments from photographic perspectives. He used a technique similar to that of V. Vozikis in his thesis in 1979. Finally, G. Fangi, Ancona/Italy, presented a new version of his stereodigitizer for the Rolleimetric system. All the papers will be published in the proceedings of the symposium which can be ordered from: Doc. Dr. Eng. J6zef Jachimski, Photogrammetric Research, Institute of M&I Geodesy, University of Mining and Metallurgy (AGH), A1. Mickiewicza 30, PL 30-059 Cracow, Poland. In the closing session the following resolution was agreed upon: "The Symposium --noting that only a small percentage of the world's historic monuments and sites are properly documented, --recognizing the new possibilities of photogrammetric recording with the use of non-metric and partially metric cameras and simple restitution systems, --recognizing also that appropriate control information could further facilitate the documentation, --recommends that an effort should be placed on: --the design and formation of simple and economic systems, and --further studies for the optimisation of control information." In Cracow there were about one hundred specialists of architectural photogrammetry, seventy of them coming from sixteen countries outside of Poland. Unfortunately, this is not enough to ensure that the agreement to cooperate to protect and preserve the architectural and archaeological heritage will be successful. Mankind is still not and never will be secure from the threat from people who willingly and brutally destroy what we have all inherited from our ancestors. The next, the fourteenth International Symposium of architectural photogrammetry of the CIPA, the International Committee of Architectural Photogrammetry, will take place in Delphi, Greece, from October 2nd to 5th, 1991, and will be organized by: Prof. Dr. John Badekas, Laboratory of Photogrammetry, National Technical University of Athens, 9, Iroon Polytechniou, GR-15573 Athens, Tel (00301) 7708650/Fax 7708550. The theme of the symposium will be "Architectural Photogrammetry and Information Systems". Applications for the presentation of papers should be sent to the address above as soon as possible. The two days before the beginning of the symposium a training seminar on practical architectural photogrammetry will take place, organized by Dr. A. Georgopoulos, Athens, and R.W.A. Dallas, York, U.K. The costs will be US$ 400. On the occasion of the symposium for architectural photogrammetry there is always a very interesting excursion to some famous monument guided by top experts. From Cracow, for ex-
