Notes: The author outlines his experiences of photographic surveying, in the early years of the 1930's in the Survey of India, which involved the use of simple graphical methods of plotting.

Notes: Aerial photography may be used to quickly locate and measure the extent and severity of forest damage due to windblow. This paper describes such an application in a small area of semi-natural woodland in central Scotland after the “Great Gale” of 14th and 15th January, 1968. A 1 : 2000 scale map, showing the location and direction of fall of each windblown tree, suggests certain relationships between topography and the severity of woodland damage and gives considerable information on the airflow pattern existing over the area during the gale.

Notes: The International Society for Photogrammetry held the XIIth International Congress at Ottawa during July and August 1972. The authors comprised a panel which engaged in discussion upon the Congress at a meeting of the Photogrammetric Society on 17th October, 1972.

Notes: The Photogrammetric Society was formed in 1952. The Council of the Society considered that the twentieth anniversary was a good point at which to record the events which led to its formation and the significant occasions and decisions which have taken place since 1952. Consequently, Paul Lamboit was invited to compile this History. He has placed the birth and development of the Society within the national and international photogrammetric context and his record of the deliberations which took place between 1947 and 1952 will be of particular interest to historians of our subject.This account was first published in a limited edition in 1971. Sufficient interest has since been expressed to prompt a wider circulation through publication in the Photogrammetric Record.The author served the Society continuously in several official capacities from 1953 to 1969 and he was elected to Honorary Membership in 1969.〈section xml:id="abs1-2"〉〈title type="main"〉RésuméLa Photogrammetric Society a été fondée en 1952. Excellente occasion pour faire le point qu'un vingtiéme anniversaire, a estimé le Conseil de la Société; pour rappeler les circonstances de sa naissance, les étapes de sa croissance et les décisions importantes prises depuis 1952. Ce qu'on invita Paul Lamboit à faire. Son exposé resitue la naissance et le développement de la Société dans le contexte national et international de la photogrammétrie; la relation qu'il fait des décisions prises entre 1947 et 1952 intéressera particulièrement ceux qui s'occupent d'histoire de la photogrammétrie.Ce rapport d'abord publié en édition limitée en 1971, a suscité un intérêt suffisant pour que l'on se presse en le publiant dans le Photogrammetric Record de le porter à la connaissance d'un plus large public.L'auteur a exercé différentes fonctions de 1953 à 1969 dans l'appareil de la Société. Il a étéélu membre honoraire en 1969.〈section xml:id="abs1-3"〉〈title type="main"〉Zusummenfussung1952 wurde die Britische Gesellschaft für Photogrammetrie gegründet. Der Rat der Gesellschaft erwog, dass der zwanzigste Jahrestag eine günstige Gelegenheit sei, um die Ereignisse, die zur Gründung der Gesellschaft führten sowie die bedeutenden Veranstaltungen, die stattfanden und die Entscheidungen, die getroffen wurden, darzustellen. Aus diesem Grunde wurde Paul Lamboit eingeladen, diesen historischen Rückblick zu schreiben. Er hat dabei die Gründung und die Entwicklung der Gesellschaft in den nationalen und internationalen photogrammetrischen Zusammenhang gestellt nd sein Bericht über die zwischen 1947 und 1972 erfolgten Beratungen wird für an unserer Sache interessierte Historiker sehr aufschlussreich sein.Diese Zusammenstellung wurde erstmals in einer begrenzten Auflage im Jahre 1971 veröffentlicht. Genügend Interesse wurde inzwischen bekundet, um eine weitergehende Verteilung mit Hilfe des Photogrammetric Record zu veranlassen.Der Autor diente der Gesellschaft kontinuierlich in verschiedenen Ämtern von 1953 bis 1969, wo er aum Ehrenmitglied gewählt wurde.

Notes: A phototheodolite was used during the construction of Llyn Brianne dam to provide stereoscopic coverage of both upstream and downstream shoulders of the dam at each of eight stages of construction. Ground control was established on the valley sides, together with 80 targeted points at various levels on the dam as it progressed. The co-ordinates of the targeted points were determined numerically using a Wild A7. Three dimensional displacements were determined from the change of position to an average accuracy of 0–05 m. Agreement was obtained with independent and more precise measurements and comparisons are made with the upstream displacements. The assumptions of an analytical prediction technique are examined. Profile lines through the dam were also obtained numerically to record the progressing shape of the dam.
