Wooden utility poles are used to carry power and telephone lines and are made of preservative treated timbers. The service life of a wooden utility pole is dependent on many factors, the most important of which is the reduction in fibre strength caused by wood decaying fungi (Morrell et al. 1985; Ribera et al. 2017). Therefore, it is essential to quantify the presence of fungal deterioration to estimate the remaining lifetime of the pole. In 2018, a project led by NORCE and funded by the Norwegian Research Council and Nettpartner Holding AS was started to investigate the capabilities of using remote sensing for the inspection of wooden utility poles. One of the remote sensing modalities in this research is hyperspectral imaging.
