The Administration of Italian Cadastral Survey, in the course of the last 
ten years has given special care to cadastral mapping of the Municipality of 
Rome, carrying out new surveys and bringing up-to-date those performed in 
recent times, in order to follow the frequent and rapid transformations which 
already have and will occur, specially in the area of the city itself. 
In performing this work it was not possible not take into account the 
particularities of Rome, where the passing of centuries has left its profound 
and admirable traces of the events of which the Eternal City was a centre as 
well as of the civilization which started from it and bestowed it with an in- 
comparable attraction in the spiritual world. 
Though the cadastral surveying work has been carried out according to 
its particular civil, fiscal and geodetic purposes, it was endeavoured to furnish 
also an appreciable contribution to the knowledge of Rome from a cultural 
point of view and to supply a further topographic basis for future archæologic 
studies and researches. 
In the surveying program the compilation of apposite sheets on scale 
1:500 was therefore foreseen for particularly interesting areas from an archæo- 
logic point of view, and specially for the zone of the Palatinum, the hill which 
preserves the most antique memories of Rome, consisting of imposing ruins, 
strewn between an impressive vegetation and offering the view of a marvellous 
panorama. 
From a technical point of view, it was preferred — also referring to the 
map scale — to apply a combined surveying method, i. e. using for planimetry 
the tacheometric survey already carried out or still to be performed and ap- 
plying then air photogrammetric methods for completion by other planimetric 
details as well as for plotting of contour lines and spot-heights and for the ra- 
pid ascertainment of cultivations. 
From the archzologic point of view it was retained’ opportune to
