Lo stereocartografo Santoni modello IV : cronaca di un salvataggio / Paolo Brenni, Anna Giatti.
Abstract:
The Fondazione Scienza e Tecnica of Florence has recently acquired a Santoni Model IV stereocartograph. This large instrument was used for producing topographical maps from stereoscopic aerial or terrestrial photographs. This type of stereocartograph had been proposed in 1943 by Ermenegildo Santoni (1896-1970), who invented and perfected several types of similar apparatuses over a period of many years. The instrument, which is purely analogical and represents one of the last apparatus of this kind, is a masterpiece of precision mechanics. Today all these apparatus are completely superseded by computers and plotters
