Abstract
In order to teach and work effectively at survey and photogrammetry, one should understand basic semiological abbreviations which derived form foreign languages to Japan. This paper describes that several technical abbreviations in surveying correspond closely with Dutch words which were imported into Japan in the Edo era (1600-1867) .It was considered that, as established theory, symbols“B”and“L”were German abridgments of“Breite”and“Länge” (i.e. latitude and longitude), respectively, by force of making an amendment form French triangulation system to German triangulation system which had employed by the military serivice of Japan in 1882.Nevertheless, “B”and“L”also coincide with Dutch terms of“breedte”and“lengte..which were transfered to Japan at least since 1803. Moreover, it reveals that symbols“B”, “P”and“C”being utilised for eccentric triangulation might be said as abridgments of Dutch terms form“bevordelijk standpunt”for instrumental center, “piramidaale centrum”for center of measuring tower (namely“pyramid”) and“centrum van geodesische monument”for center of hurried mark, respectively.
