Application of sentinel-2a image in shallow water depth inversion of Lingshui Sanya coast

2021 7th International Engineering Conference “Research & Innovation amid Global Pandemic" (IEC), 2021
The flexibility of traditional bathymetric measurement technology is poor, and the update cycle of bathymetric data is long and the timeliness is poor. Remote sensing technology is used to carry out bathymetric inversion to make up for the deficiency of traditional oceanographic measurement to some extent. Based on the in-situ measured water depth data

Water depth inversion from satellite dataset

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
Within an effort to estimate near-shore bathymetry from satellite scenes, a method based on wave celerity and wavelength estimation is developed. These wave characteristics are extracted from SPOT-5 panchromatic and multispectral scenes. The method allows us to associate the wavelength and the celerity of the same detected wave and to estimate the ...

Water Depth Inversion in Sanya Bay Based on TM Image

Applied Mechanics and Materials, 2013
Remote sensing technology can be applied to water depth measurement in coastal area [. In this paper, Sanya Bay was chose as the study area. The author combined high spatial resolution TM image and observed water depth data for water depth inversion. The power exponential model based on TM2 is selected because of its least average relative error in all

Water-depth-zoning inversion based on the relationship between two-band radiance data and the depth-invariant index

Regional Studies in Marine Science, 2021
Abstract Water depth is important in hydrology and is often estimated by remote sensing. Studies have shown that different substrates have a certain influence on satellite derived bathymetry (SDB). In this work, the depth is estimated after the depth-invariant index used to perform substrate classification.
