Keywords: 3D Models, Laser Scanning, Resolution, Accuracy, Surface Comparison, Topography

Abstract. The paper will present the extraction of information from a laser scanning survey aimed to support historical studies on the Sangallo's house in Florence. In order to verify some study's hypothesis related to the building history and constructive techniques, high resolution models were needed. The meaning of "resolution" applied to 3D scanning will be briefly discussed stressing the difference between resolution and accuracy.

Starting from the analysis of technical specifications of the used instruments, the expected performance of the model is described. The results obtained from acquired data are shown and the paper will conclude proposing some answers to the historian's questions.
