Whitten) has prepared similar memoirs for three Presidents of the old Association and also concise bio-reference notes for deceased former Section, Commission and Special Study Group officers as well as other geodesists who have made significant contributions. In order to provide a continuous information about the history of the Association, the Central Bureau has prepared biographical memoirs of two former Presidents of the Association and one Secretary General who recently ended their terms of office.

Eratosthenes (circa 276 B.C.–194 B.C.) is considered a famous scientist of ancient Greece. He was a mathematician and geographer. Born in Cyrene, now Shahhat (Libya), he was appointed to teach the son of the Egyptian King Ptolemy III Euergetes. In 240 B.C., he became the third chief librarian the Great Library of Alexan- dria. Eratosthenes laid basics for mathematical geography. He was the first to calculate precisely in an original way the Earth meridian’s length between Syene and Alexandria. For this purpose he used perpendicular projection of the sun rays during summer solstice (06.22) near the town Syene, now Aswan. His estimation of the length of the Earth’s radius (6300 km) is close to present estimation (6371 km). He calculated that a year possesses 365.25 days. He also emphasized the significance of maps as the most important thing in geography. Eratosthenes was the first one to use the term “geographem” to describe the Earth. In this way he legitimized the term of geography. He also put into system geographical information from various sources in order to obtain a map of the world as precise as possible.

The systems are needed because the earth is an imperfect sphere. Also the earth is an imperfect ellipsoid. This can be verified by differentiating the equation for an ellipsoid and solving for dy/dx. It is a constant multiplied by x/y. Then derive the force equation from the centrifugal force acting on an object on the earth's surface and the gravitational force. Switch the x and y components and multiply one of them by negative one. This is the differential equation which when solved will yield the equation for the earth's surface. This is not a constant multiplied by x/y. Note that the earth's surface is also not an equal-potential surface, as can be verified by calculating the potential at the equator and the potential at a pole. The earth is an equal force surface. A one kilogram frictionless object on the ideal earth's surface does not have any force acting upon it to cause it to move either north or south. There is no simple analytical solution to this differential equation.

The history of geodesy can be traced back to Thales of Miletus ( ∼ 600 BC), who developed the concept of geometry, i.e. the measurement of the Earth. Eratosthenes (276–195 BC) recognized the Earth as a sphere and determined its radius. In the 18th century, Isaac Newton postulated an ellipsoidal figure due to the Earth’s rotation, and the French Academy of Sciences organized two expeditions to Lapland and the Viceroyalty of Peru to determine the different curvatures of the Earth at the pole and the Equator. The Prussian General Johann Jacob Baeyer (1794–1885) initiated the international arc measurement to observe the irregular figure of the Earth given by an equipotential surface of the gravity field. This led to the foundation of the International Geodetic Association, which was transferred in 1919 to the Section of Geodesy of the International Union of Geodesy and Geophysics. This paper presents the activities from 1919 to 2019, characterized by a continuous broadening from geometric to gravimetric observations, from exclusive solid Earth parameters to atmospheric and hydrospheric effects, and from static to dynamic models.

The review starts with the frst measurement of the meridional arc length in Japan by Tadataka Ino (1745– 1818) early in the nineteenth century, done as a part of the mapping campaign of the country. Next, I mention the frst international recognition of Japanese geodesy realized by the discovery of a new term in the Earth’s polar motion by Hisashi Kimura (1870–1943) at the beginning of the twentieth century. Finally, I review an unsuccessful campaign to detect present-day continental drift in Japan shortly before World War II, conducted by the Geodetic Committee of Japan being inspired by the hypothesis of active opening of the Sea of Japan by Torahiko Terada (1878–1935).

  • Measuring the Circumference of the Earth
    Measuring the circumference of the earth It wouldn't be a history of math course without showing how the Greek mathematician Erastosthenes (276{194 BCE) calculated the size of the earth. First of all, the ancient Greeks (and they weren't the only ones) knew perfectly well that the earth was round. Looking at ships' masts as they disappeared over the horizon was one piece of evidence. Lunar eclipses (where the earth is directly between the sun and moon) are further evidence: you can see the earth's curved shadow falling on the moon. Once you believe that the earth is curved, a sphere is the simplest possibility. They also knew that the sun was very very very very far away from the earth (our modern measurement is about 93 million miles). So Erastosthenes started by assuming the earth was a sphere. He assumed that because the sun was so far away, the sun's rays striking two places on earth that weren't very far away from each other were nearly parallel. He also knew that the sun shone directly into a particular well at Syene, Egypt (in modern-day Libya) at the summer solstice. He knew that Alexandria was 5000 stadia (a unit of length; the singular is stadium) north of Syene, and that a staff in Alexandria cast a short shadow when the sun was at its zenith.1 Erastosthenes put all this information together in the following diagram. S Sun’s rays Alexandria θ T B Sun’s rays D well Syene φ C B: base of staff C: center of earth earth’s center D: shadowless place S: tip of staff T: tip of shadow The diagram, of course, is not at all to scale|the staff is much smaller in real life than in the diagram.

  • GEOMETRIC GEODESY Part 2.Tif
    GEOMETRIC GEODESY PART II by Richard H. Rapp The Ohio State University Department of Geodetic Science and Surveying 1958 Neil Avenue Columbus, Ohio 4321 0 March 1993 @ by Richard H. Rapp, 1993 Foreword Geometric Geodesy, Volume 11, is a continuation of Volume I. While the first volume emphasizes the geometry of the ellipsoid, the second volume emphasizes problems related to geometric geodesy in several diverse ways. The four main topic areas covered in Volume I1 are the following: the solution of the direct and inverse problem for arbitrary length lines; the transformation of geodetic data from one reference frame to another; the definition and determination of geodetic datums (including ellipsoid parameters) with terrestrial and space derived data; the theory and methods of geometric three-dimensional geodesy. These notes represent an evolution of discussions on the relevant topics. Chapter 1 (long lines) was revised in 1987 and retyped for the present version. Chapter 2 (datum transformation) and Chapter 3 (datum determination) have been completely revised from past versions. Chapter 4 (three-dimensional geodesy) remains basically unchanged from previous versions. The original version of the revised notes was printed in September 1990. Slight revisions were made in the 1990 version in January 1992. For this printing, several corrections were made in Table 1.4 (line E and F). The need for such corrections, and several others, was noted by B.K. Meade whose comments are appreciated. Richard H. Rapp March 25, 1993 Table of Contents 1 .
