Abstract

Today it is possible to easily access advanced equipement both for 3d and photographic scanning, but in this field it can often happen to acquire the data using emergency procedures. In this case the improvisation can become essential: if we cannot be provided specialized equipment, or if we need to work only partially officially, simply for the lack of authorization, or because during a visit we find an interesting theme. Evaluating several experiences, it can be useful to understand the limits and advantages of the procedure. This contribution has not the aim to presenting itself as a collection of indications for illegal reliefs, but to be useful in an analysis and to explain the limits and advantages in this low cost procedure, giving the indications to work effectively in emergency and adverse conditions.
