Abstract

Automatic landform recognition is considered to be one of the most important tools for landform classification and deepening our understanding of terrain morphology. This paper presents a multi-modal geomorphological data fusion framework which uses deep learning-based methods to improve the performance of landform recognition. It leverages a multi-channel geomorphological feature extraction network to generate different characteristics from multi-modal geomorphological data, such as shaded relief, DEM, and slope and then it harvests joint features via a multi-modal geomorphological feature fusion network in order to effectively represent landforms. A residual learning unit is used to mine deep correlations from visual and physical modality features to achieve the final landform representations. Finally, it employs three fully-connected layers and a softmax classifier to generate labels for each sample data. Experimental results indicate that this multi-modal data fusion-based algorithm obtains much better performance than conventional algorithms. The highest recognition rate was 90.28%, showing a great potential for landform recognition.
