The recent technological advancements in the field of digital photogrammetry together with the
improvement of computational methods for image analysis have been show to aid laser technologies in
architectural measurements, yielding high-resolution surveys of unprecedented resolution. In theory (and
in many real applications) an integrated survey coming from both laser scanning and photogrammetry
is able to meet all the requirements to perform a correct architectural survey, both in terms of the
centimeter resolution and for fine aesthetic representations.
The presented study deals a survey of the attic and the top surface of the domes of the left and right
naves of the San Francesco Basilica in Ferrara (Italy), in which not all the ideal conditions required
for a good quality integrated survey are present. Different practical problems may pose due to a
recent earthquake (2012). The present job will be focused on survey planning and performing, in such
emergency condition, on the used techniques and the final products. The results of such survey will be
used for a future restoration of the Basilica
