The rule image of the class "buildings" enabled us to recognize As far as archeological instances are concerned dimensions and
circular anomalies approximately 100 m from the west side of placement of terrain anomalies that could be correlated to
the Sant' lario monastery (figure 10). archeological evidences show how the geometric problem is
again important. Accurate positioning is necessary for precise
terrain investigations. Shapes are important for understanding
nature of the anomalies. The test areas analysis has identified
some interesting anomalies that have to be checked on the
ground.
