The development of new survey methods, in particular the 3D laser scanners, has generated new, miscellaneous problems for the surveyor. In the past, the survey points used to create a model were chosen before the measurements were taken; today instead, this choice is made later. The new laser methodologies automatically record the data (points cloud). .Only afterwards is the data elaborated differently in order to create a numeric or geometrical model 01 the surveyed object. In other words, while in the past the surveyor played a critical role before the survey process began by selecting the data, new technology now assigns him a "post-process" role, often resulting in the mere use 01 semiautomatic techniques. However, this radical change undoubtedly induces an identity crisis in surveyors, especially those who belong to that large group of surveyors who normally carried out their job using the direct or photogrammetric procedure which considered the discretionary choice 01 data to be surveyed as an extremely important cultural rite. In order to study the critical moment that representation is going through, Disegnare. Idee immagini decided to invite two lecturers, experts in this field, to discuss this problem with the Editor in order to assess its importance as well as its repercussion on research.
