This paper has a double objective: firstly, to analyse the photos produced by Emilio Sereni in the 1950s, as well as the scientific reasons which made Sereni to shoot numerous pictures of Polcevera Valley (GE) rural landscapes. Specifically, Sereni’s work hypothesis on the ‘marrelo’ Ligurian agrarian landscape have been assessed, using his notes and correspondence. Secondly, one of the Sereni’s photo has been used to verify the potentialities offered by a new monoplotting software for the georeferecing and the vectorisation of photos taken from the ground. Digital processing allows to compare photographic source with cartographies and aerial photos, for a diachronic quali-quantitative analysis of ‘marrelo’ presence and extension from XIX c. to nowadays.
Keywords: History of agrarian landscape, Emilio Sereni, historical photography, monophotogrammetry.
