WebIn this study, a deep learning convolutional neural network (CNN) algorithm was employed to extract relict charcoal hearth features from LiDAR data. With the application of CNN algorithms on LiDAR based slope maps and edge detection rasters, the network was successfully able to identify locations likely to be RCHs.
