Convolutional neural networks (CNNs) effectively classify standard datasets in remote sensing (RS). ...
Instead of training a model on a smaller, human-labelled dataset, we semiautomatically created training data using an ancillary normalised Digital Surface Model (nDSM) and image spectral information. ...
This fact allowed us to use aboveground heights (where nDSM is available) as a feature to create the training and validation dataset. ...
