The techniques related to the photogrammetric survey are even more widely used in the field of Cultural Heritage In fact, they allow a representation of artifacts with a high attention to the geometric detail by a vector restitution and a high definition of the textural aspects of objects: they based on the creation of photo-plans, which provide information both metrics and qualitative about the object. These techniques, therefore, are an essential tool supporting diagnostics and restoration of ancient monuments. This article discusses the methodology, the operational phases and the instruments used for the photogrammetric survey of a building complex: the Castle of Maredolce in Palermo. In this case the geometry of the building, the uneven ground and the pres ence of physical elements creating shadows on the building have significantly affected the operations of relief: they have allowed to address and solve a wide range of issues deriving from the survey of historic buildings that are located in a urban context today. This paper, in particular, describes the workflow and the procedures used until the 3D image-based modeling. The latter was implemented from the georeferenced photogrammetric block obtained by the orientation of the frames. The photo-plans of the castle have been used as photo-realistic texture of the photogrammetric three-dimensional model.
