New surveying techniques, such as 3D terrestrial laser scanning, allow the collection of specific spatial and structural data of cultural heritage monuments. These techniques make the creation of accurate and reliable 3D models possible.
 
Information obtained in this way can be used for the purpose of protection, conservation and valorization of architectural, archeological and other important heritage sites. Such data and 3D models can be used for the analysis of the structures and for reconstruction in case of damage or devastation.
 
Preparation is the first step, which if done correctly, ensures optimal results. In all cases this means an inspection of the site and finding station positions that will allow the 3Dscan of all details of interest to the best of possibilities. ‘Line of sight’ has to be taken into account as in some cases many features can be obstructed. Survey target positions need to be chosen carefully in order to align each scanner location in the final 3D point cloud model.
 
This methodology can also be used to monitor deterioration of sensitive sights by simply scanning the existing sight periodically and comparing data sets. Software exists to detect changes from one data set to the next and automatically high light variances.
 
3D laser scanning is a non-invasive process and can be conducted at a distance from the subject, depending on the instrument used.  Areas of interest can be captured from the ground often eliminating the need to climb or interact with the subject in any way.  This also reduces the potential for safety issues as would often be the case captureing this type of information traditionally.
