6. FINAL CONSIDERATIONS 
The work described in the previous pages involved several 
professional I.G.M.I.'s figures, such as photogrammetric photo- 
graphers, surveyors, stereoplotter and workstation opera- 
tors; such personnel were engaged to their utmost in order 
to face and solve the encountered technical problems. 
The demonstrated care and passion and the achieved result re- 
present, on the part of all the personnel at I.G.M.I., a civil re- 
sponse to the attack that mutilated a patrimony of Italian lear- 
ning.
