Overview
canObsR is a R package which aims at streamlining, standardizing and facilitating processing of repetead UAV surveys. It notably allows generating 3D and 4D mosaics & mosaics spatial alignment using state-of-the-art approaches. canObsR is also used to do phenological monitoring at the individual tree level. It gives tools to build a database with pictures of individual crown overtime, spectral indices of crowns overtime, add labels to classify pictures and analyse the phenological and the spectral data.
