Informations In Memoriam Professor Karl Rinner 1912-1991

It is the intent of the IAG to extend the services provided by its Central Bureau. An up-to-date information medium is one of the key elements. The IAG Newsletter, included as appendix of the Bulletin G6od6sique, should play this role, and therefore be considered as an open forum. Contributors are welcome to send any information or document which may be of interest for this purpose. This should supplement the informations already sent by the IAG officials or the IAG symposia organizers (reports and anouncements). Books to be reviewed are under the responsibility of : Prof. Gunther W. Hein Institute of Astronomical and Physical Geodesy University FAF Munich Wemer- Heisenberg - Weg 39 W - 8014 Newbiberg - FRG

For years Karl, Rinner had fought bravely and very sucessfully against a malicious illness. He had been instrumental in bringing the XX General Assembly to Austria, where it took place in Vienna on August 1t-24, 1991. He had felt quite well and looked forward to be the Chief Delegate for Austria at this Assembly. A few days before the Assembly the unexpected occured: he had to be brought to a hospital, and a few days after the Assembly, on August 27, 1991 he died in Graz.

244 Karl Rinner was born on October 4, 1912 as the fifth child of an innkeeper in the small village of Gratkorn near Graz. Already at a very early stage he showed to be an extremely gifted boy, so that he commuted daily to Graz to attend a secondary school specialized in mathematics and natural sciences. After that, he began to study simultaneously mathematics at Graz University and surveying and geodesy at the Technical University. Soon, he found pure mathematic too much of an ivory-tower discipline for him. Thus he turned definitively to surveying, where he got particularly interested in the geometry of photogrammetry. In 1936, he graduated as a Diplom-Engineer. Few months later, he received the degree of Doctor of Technical Sciences, using as doctoral thesis a paper which had already previously been published by the Austrian Academy of Sciences ("On Wiener's Imaginary Projection"). Then he found immediately an interesting and responsible position in the Geodetic Survey of Bavaria in Munich, first in triangulation and then in photogrammetry. In the meantime, the Second World War had begun. In 1940, Karl Rinner joined the German Navy as an engineering officer in the rank of lieutenant-commander. His high-rank scientific position enabled him to stay in Berlin, where he habilitated as a privatdocent at the Technical University in Berlin. In this hard time, he managed to publish important scientific contributions, incidentally founding Marine Geodesy. After the war, he returned to Gratkorn. In order to maintain his family of two sons and five daughters, he had to work as a free-lance surveying engineer, running in Graz one of the best known surveying offices in Austria. He specialized in difficult projects of engineering surveying; as an example, he surveyed 8 tunnels through the Alps, of a maximum length of 11 km. Besides this demanding work, he still found time and energy to habilitate for a second time as docent at the Technical University in Graz in 1953. The author of this article had the privilege to attend his lectures on electronic distance measurement and analytical photogrammetry. He rapidly became internationally known. In 1957, he was appointed Director of the well-known Geodetic Research Institute in Munich, while still retaining his surveying office in Graz. In 1960, he was appointed Full Professor at the Graz Technical University. His work on analytical photogrammetry, satellite geodesy, etc. brought him international recognition. He was a pioneer in

establishing a Computing Center in Graz, as well as the Satellite Observation Station Graz-Lustbiihel, stations for observing earth-tides, the Graz test, etc. His work is contained in some 200 publications and several textbooks. His scientific and practical experience made Karl Rinner an outstanding and inspiring academic teacher. He set high standards for his assistants and students, expecting them to work (nearly) as much as he himself did. On the other hand, he was always ready to help and to promote them, and he left many people, including the present author, who have strong reasons to be grateful to him. He was the "prime mover" in establishing the Graz geodetic school in an international sense. He also actively engaged himself in working for his university. In 1963-1965, he was Dean of the Faculty of Civil Engineering, and in 1970-1972 Rector of the Graz Technical University. After his retirement from university in 1983 he still worked as Director of the Satellite Observation Station Graz-Lustbiihel of the Austrian Academy of Sciences until 1989. From 1979 to 1988, he was President of the Austrian Geodetic Commission and from 1980 until his death President of the Austrian National Committee for IUGG. The outstanding scientific merits of Karl Rinner found ample international recognition. For instance, he got honorary doctorates: In 1974 TU Darmstadt and in 1981 TU Hannover, and he was elected Corresponding Member of the Austrian Academy of Sciences in 1974, and its Full Member in 1975. In 1976, he became Honorary Member of the Hungarian Academy of Sciences. Karl Rinner involved himself at an early stage in the work of lAG: From 1967 to 1975 he was Chairman of a Special Study Group on Combination of Terrestrial and Satellite Networks. Then, from 1975 to 1979, he was President of Section I of IAG. From 1972 to 1984 he was President of its Commission on Education. Finally, from 1987 to 1991, he was Third Vice-President of IAG. He also organized two IAG symposia in Graz: In 1972 on satellite triangulation and in 1982 on education. Karl Rinner was perhaps the last geodetic universalist, equally at home in surveying, photogrammetry and geodesy. He was as great as a scientist as he was as a man: his work will be of lasting importance, and he will be gratefully remembered by his family, his students, his colleagues and his friends.

James G. Marsh 1939-1991

Title (Mr/Mrs., Dr., Prof...) .......................................

Jim Marsh, a member of the Laboratory for Terrestrial Physics and a Goddard Space Flight Center employee since 1964, died at home on the morning of June 30, 1991. Jim was a prominent NASA contributor in the field of Satellite Geodesy and was instrumental in developing a space geodesy capability at Goddard since the middle-1960's, He had over 100 publications with more than 80 being in the refereed literature. Jim's accomplishments included investigations of the applications of satellite observations for measuring the size, shape, gravitational, and tidal field of the Earth and developing models for improved orbit determination. These investigations produced both the NASA standard and internationally recognized state-of-the-art gravitational models used for geophysical and orbit determination purposes.

First name(s) or initial(s) ...........................................

Jim also led an investigative group studying applications of satellite altimetry to develop models of the ocean's topography using data acquisired by the U.S. Navy's GEOSAT and NASA's GEOS-3, SEASAT, and the tobe-launched TOPEX/Poseidon satellites. These investigations improved existing models of the ocean geoid, provide more detailled knowledge of the ocean bathymetry over uncharted regions, and demonstrated the utility of altimeters for monitoring the circulation of the world's ocean current systems. Jim was known throughout the Geodetic Community as a charitable person, who readily shared his data and models with those seeking his help. His professional accomplishments attest to his scholarly ability; his personal traits portrayed a gentle person and a man in the finest sense of this world. He served as the Secretary for the Geodesy Section of the American Geophysical Union and received numerous NASA and International Awards the including NASA Exceptional Service Medal in 1980. Jim was a Principal Investigator within the GEOS-3, SEASAT, LAGEOS, LAGEOS-II, TOPEX and Crustal Dynamics Projects. He is survived by his wife Phyllis, son Matthew and daughter Melissa.

Report : Following an initiative of the International Association of Geodesy (IAG), the 1st International Symposium on Applications of Geodesy to Engineering was arranged at the University of Stuttgart May 13th - 17th 1991 by the Institut fiir Anwendungen der Geod~isie im Bauwesen (Prof. Dr.-Ing. K. Linkwitz) and the Landesvermessungsamt Baden-Witrttemberg (Pr~ident Dipl.-Ing V. Eisele). The meeting, with more than 100 participants from 20 different countries, was opened by the Rektor of the University of Stuttgart Magnifizenz Prof. Dr.-Ing. J. Giesecke, the chairman of the organization committee Prof, Dr.-Ing. K. Linkwitz, and the Vice-President of the IAG Prof. Dr.-Ing. W. Torge. In 13 sessions concerning the fields. - theoretical aspects, - techniques of measurements, - techniques of data processing and computing,

246 - reports about selected executed projects, special tasks, i.e. realtime positioning and navigation, industrial measurements, image processing, - the role of the geodesist in collaboration with civil and mechanical engineers, technical designers and architects. -

38 papers were presented, thereof 14 by invited speakers. The presented papers gave a general view of the whole field of Engineering Geodesy and the state of research and development in this field, also with a view on collaboration with engineering in general. Some fundamental contributions were given in the fields. 1. theoretical aspects: networks in a threedimensional reference frame (E.W. Grafarend), GPS as a tool for engineering applications of geodesy (V. Ashkenazi), new models of the deformation analysis (H. Pelzer) and geodetic methods for formfinding of leightweight surface structures (K. Linkwitz); 2. techniques of measurements: robot techniques and their impact on surveying systems (H. Kahmen);

relevant places were offered: Daimler Benz, Carl Zeiss, the Solebad Bad Diirrheim as a remarkable example for formfinding of surface structures with geodetic methods, a tunnel construction and the State Department of Geodesy and Cartography (Landesvermessungsamt) in Stuttgart. Initiated by the Vice-President of the IAG, W. Torge, during the symposium an ad-hoc group for the preparation of resolutions in the symposium itself and further activities on the subject within the IAG constituted itself, consisting of L. Grtindig (Germany), H. Henneberg (Venezuela), H. Kahmen (Austria), N. Korittke (Germany), K. Linkwitz (Germany), M. Mayoud ((Switzerland), H.J. M6nicke (Germany), S. Mogilny (USSR), H. Pelzer (Germany), J.M. R~ieger (Australia) and K.P. Schwarz (Canada). In the final session of the symposium the following statements and resolutions were presented to the plenum by the chairman Prof. Linkwitz, discussed and finally approved and written in a letter to the President of the IAG, Prof. I. Mueller. I-

3. techniques of data processing and computing: data base systems for applications in engineering (H-J. Schek), recent developments with respect to the automated processing and analysis of engineering survey data (L. Griindig), theoretical foundations of technologies by using the system "analogous stereo plotter and personal computer (S. Mogilny); 4. reports about selected executed projects: applied geodesy for particle accelerators (W. Schwarz), large structures in Venezuela (H. Henneberg), a digital urban space model for urban planning and management (R. Schibasaki and H. Nakamura); 5. special tasks: application of network adjustment techniques in engineering (J. Bahndorft et al.), special measurement methods to determination of the dynamic parameters in bridge systems (U. Pahnke); 6. the role of the geodesist in collaboration with civil and mechanical engineers, technical designers and architects: the cooperation of surveyors at the improvements of the infrastructure in developing countries. In the other papers reported about interesting current investigations, works and projects from the whole field of geodesy in engineering. These were topics to tidal corrections, inertial measurement problems, measurements of rigid body motions, hybrid measurement systems, processing of heterogeneous data, threedimensional static and kinematic networks, deformation measurements and analysis, realtime positioning, robot vision, image matching and large structure projects such as the Canal Tunnel, long under sea tunnels in Japan or hight transfer across the Great Belt.

Preambel

regarding the impact of rapid developments in engineering, micro-electronics and the computer sciences upon geodesy, and realizing most challenging tasks for the geodesist/surveyor originating in and stemming from engineering, - the participants of the 1st International Symposium on Applications of Geodesy to Engineering consider it to be appropriate that the field of "application of geodesy to engineering" be accomodated in the IAG. In mutual agreement with the FIG this could be in the form of a "Special Commission" to be established in the Vienna Congress of the IAG in August 1991. II-

Objectives

of

a

potential

commission

2. Specific: "Working fields" 2.1. Theory of local networks and local reference frames with the purpose of integrating distinctive methods (i.e. trilateration, levelling, INS, GPS). 2.2. Realtime measurements and their evaluation and analysis with the purpose of realtime monitoring of moving objects. 2.3. System developments for applications in engineering, using multi-sensor approaches. 2.4. Acquisition and processing of large data amounts using modern concepts of micro electronics and the

247 information sciences as a basic for high frequency continuous measurements. The symposium was sponsored by the IAG and FIG and integrated in the IAG series of symposia under N°108. All contributions will be published in a proceeding volume by Springer-Verlag New York.

Report to the Executive Committee of IAG on behalf of Ad Hoc Working Group "Geodetic Aspects of the Law of the Sea" (GALOS). The establishment of this Ad Hoc Working Group was authorized by the president of IAG on April 21st, 1989 and ratified by the EC of IAG at its meeting on March 15-16, 1990. The mandate of GALOS was to "formulate recommendations concerning geodetic aspects of international maritime boundary delimitation within the framework of the Law of the Sea Convention 1982; and to write a report describing the various possible scenarios admissible under the Convention from the point of view of geodesy". The geodetic tasks involved were to be: a) accurate area determination, b) definition of off-shore limits (both geometrical and in the sense of article 76), c) definition of equidistant boundaries, d) definition of partial effect boundaries, e) determination of base points. Ad Hoc Working Group GALOS now has 12 members from 8 countries (Canada, US, Indonesia, France, UK, Germany, Sweden, New Zealand) and 1 associate member• It has held 3 meetings (Edinburgh, August 89; Monaco, May 90 and Miami, October 90) and will hold both a technical and business meeting here in vienna (21st and 22nd August)• It will also be staging an international conference on Geodetic Aspects of the Law of the Sea in Bali (Indonesia) in June 1992 with one of its members, Prof. S. Mira of Bandung Institute of Technology acting as a convenor. This conference will have the IAG, FIG and IHO as sponsors. The technical aspects of marine boundary delimitation have been tended to by the International Hydrographic Organization with its (International Hydrographic) Bureau located in Monaco• The IHB has had for some time an active international Working Group on "Technical Aspects of the Law of the Sea" (TALOS) which recently produced a manual for the IHO member countries. Naturally, there has been a tendency within GALOS and TALOS to cooperate. The chairman of the TALOS Working Group has been a full member of GALOS from the beginning and the 2nd meeting of GALOS was joint with TALOS: GALOS members actively participated in the preparation of the TALOS manual. In Miami, both GALOS and TALOS members organized a workshop on Geodetic and legal Aspects of the LoS.

The technical meeting of GALOS in vienna will consist of 8 to 9 presentations and discussion of the topics• The intention is to publish a compendium of the presented papers, after some editing, as an interim report of GALOS. A more unified treatment of the geodetic aspects of the LoS in a published form, will, however, be necessary in the future of IAG wishes to have its say in this domain. Recommendation : We recommend that the group be formally reconstructed in one form or another with the aim of formulating recommendations concerning the LoS reflecting the geodetic way of thinking. More specific and detailed plans should be discussed with the EC of IAG.

PERMANENT COMMISSION EARTH TIDES W u h a n , C h i n a , A u g u s t 1993

Geodesy, 2nd edition, by Wolfgang published by de Gruyter, 1991.

Torge,

Torge's Geodesy was first published in German in 1975, and was translated to English in 1980. It became very popular with the students, giving a comprehensive overview of our field, but not being too heavy on the theory. But as we all know has the last 10 years been a new revolution for geodesy, and this has made a new edition very much needed. The book treats all aspects of modern geodesy (GPS), and it integrates very well geometrical, gravity field and geodynamical aspects. What is not included in this (and earlier) editions are topics like adjustment theory, map projections and ellipsoidal geometry. The book is very well illustrated with many photos of instruments and good graphs showing the basic concepts. It aims at serving as an introductory text for students in geodesy, geophysics and surveying engineers, and I am sure they wilt like the book. More mature geodesists, geophysicists and surveyors will enjoy to read an excellent overview over modern geodesy• The many references and a good index also adds to the value of the book.
