The terrestrial photogrammetry in Spain (1914-1958)

The terrestrial photogrammetry innovated the traditional topographical techniques in the fields operations and the office’s works. In the last part of the nineteenth century this technique was used in the national topographic maps. In Spain, the photogrammetrics methods was early known. But until the 1920s had not been used in the massive form. The Topographical Map of Morocco and the Topographical Map of Spain, both at the scale 1:50.000, was an example of this application. The geographer engineer José María Torroja y Miret was the most important introductory of the photogrammetry from the start of the twentieth century to the 1930s. At the beginning of the thirties years the advances of the stereographic photogrammetry produced the aerial stereophotogrammetry and the automation of the office’s works. However, the peculiar situation of the Spanish postwar years was the reason to use the terrestrial photogrammetry until 1958.
