**4. Conclusions**

The 3D scanner is the most powerful and versatile instrument used in monitoring the natural and man-related processes on short term scale. The processing/production times are short and the mapping products are flawless.

On a large scale, it can be useful for a wide range of activities. Up to the present, it was used for dynamicity analyses in geomorphology (gullying, landsliding, bank- and slope- collapsing, riverine dynamics etc.), archaeology, architecture, civil and military engineering etc.

The first practical application on the Romanian territory was carried out on the Cucuteni Ravine (Iasi County), in the Moldavian Plateau.

For small items, with minute change over time, the most recommended resolution is 1mm/1mm. For lare areas, with active dynamics over time, the most recommended resolutions are 5-6mm/5-6 mm (reducing significantly the scanning time – two or three times faster).

The mapping products resulted following the interpretations of the 3D scanning results are much more accurate that the ones produced using classic methods.
