Automatic segmentation of parallel drainage patterns supported by a graph convolution neural network

作者:

Highlights:

• GraphSAGE was applied in the segmentation of parallel drainage pattern (SPDP).

• A method of building drainage dual graph (DDG) with hydrology knowledge is proposed.

• The GraphSAGE outperforms other machine learning methods and GCNNs in SPDP.

• The knowledge-based DDG reduces the quantity of DP samples for training.
