In OU ‐ 536 road in Ceboliño (Ourense) is selected a viaduct abutment. The concrete of the abutments in this bridge is visibly affected by the surface run-off of the deck in the rainy season, so it is exposed to a high moisture level. This region is characterized by a high precipitation rate.

Object state
The methodology consists analysing different classification images through several unsupervised classifications based on a K‐means algorithm. For this purpose, a multiband matrix comprising orthoimages collected with several 3D and 2D remote sensors is created. The K‐means classifier is tested to perform several unsupervised image classifications with different numbers of classes (three, four and five classes). The goal of this approach is to determine which number of classes present a more robust classification, and to provide information on which sensor is the most suitable.
