摘要

Abstract

Benthic habitat mapping is an emerging discipline in the international marine field in recent years

providing an effective tool for marine spatial planning

marine ecological management

and decision-making applications. Seabed sediment classification is one of the main contents of seabed habitat mapping. In response to the impact of remote sensing imaging quality and the limitations of acoustic measurement range

where a single data source does not fully reflect the substrate type

we proposed a high-precision seabed habitat sediment classification method that integrates data from multiple sources. Based on WorldView-2 multi-spectral remote sensing image data and multibeam bathymetry data

constructed a random forests (RF) classifier with optimal feature selection. A seabed sediment classification experiment integrating optical remote sensing and acoustic remote sensing data was carried out in the shallow water area of Wuzhizhou Island

Hainan

South China. Different seabed sediment types

such as sand

seagrass

and coral reefs were effectively identified

with an overall classification accuracy of 92%. Experimental results show that RF matrix optimized by fusing multi-source remote sensing data for feature selection were better than the classification results of simple combinations of data sources

which improved the accuracy of seabed sediment classification. Therefore

the method proposed in this paper can be effectively applied to high-precision seabed sediment classification and habitat mapping around islands and reefs.
