Information collected during a survey carried out last October is being analyzed now and three additional surveys are planned to take place this year.
In this way, the results obtained during the different surveys will be compared and the repeatability of the applied procedures to detect damage and changes over time under different weather conditions and equipment specifications will be evaluated.

The work is being conducted by Ali Mirzazade, sub-task coordinator Jaime Gonzalez, and the group at LTU.
