Survey and gathering. Low cost documentation / Rilievo e catalogazione. Archiviazione low cost

The continuous technological advancement and in particular the great digital revolution offer new research tools that are easily applied to science. Only in survey technological advancements lead to the development of three different areas of research: the first works around the problem of data acquisition (nowadays they are able to provide, in a short time, a large amount of information with a great level of detail); the second area is more restricted because it studies and suggests new low cost solutions; the third concerns the traditional methods and their integration with the former two. The survey operation, as a process involving deep knowledge, aims at the accurate representation of the analyzed subject, and for this reason drafting a procedure that uses the interaction between direct and indirect low cost methodologies and their elaboration for the realization of 2D and 3D models would be a topic of great interest, to make the final scientific results more objective and correct. The experiment concerns a study focused on some architectural elements of the city of Rome.
