Fully-covered bathymetry of clear tufa lakes using UAV-acquired overlapping images and neural networks

•UAV-acquired overlapping images were applicable to obtaining water depth map of clear tufa lakes.•Single bathymetric methods caused depth anomalies in water areas with uniform texture or shadows.•Photogrammetric and spectral-based bathymetric methods were combined using neural network (NN).•NN-base...
