Water Depth Inversion based on Landsat-8 Date and Random Forest Algorithm

Journal of Physics: Conference Series, 2020
Abstract In view of the fact that the traditional water depth inversion model is susceptible to water quality and environmental factors, the water depth inversion model is constructed using the random forest algorithm using the high resolution remote sensing image of the Huangyan Island area and the corresponding measured water depth ...

Oil-water inversion and its generation at top and bottom of the shallow sandstone reservoir in the Northern Chepaizi area, Junggar Basin, NW China

Petroleum Exploration and Development, 2014
Based on fluid property and distribution, the reason for oil-water inversion at top and bottom of the shallow sandstone reservoir of the Neogene Shawan Formation in the Northern Chepaizi area, Junggar Basin was researched from the perspective of ...

Multiple sites HFSWR ocean shallow water depth and current inversion

Acta Physica Sinica, 2014
In order to extract the ocean dynamic parameters from shallow water, water depth, and current inversion at multiple (three or more) sites, HFSWR (high frequency surface wave radar) sea echo is developed. In this paper the inversion principle and theoretical model are presented in detail, and the proposed idea is verified for three or more than three ...

Retrieval of Nearshore Bathymetry around Ganquan Island from LiDAR Waveform and QuickBird Image

Applied Sciences, 2019
Optical remote sensing is an effective means of water depth measurement, but the current approach of mainstream bathymetric retrieval requires a large amount of onsite measurement data.

The Analysis of ETM Image's Spectral and Its Implication on Water Depth Inversion iniamen Bay [PDF]

Proceedings of the 2013 International Conference on Remote Sensing,Environment and Transportation Engineering, 2013
Dual-spectra ratio method is generally considered superior to single-spectra approach in the most previous studies for water depth inversion by ETM image. In this paper, the correlation between the ETM's spectral and the water depth is analyzed. TM2 gives the largest absolute correlation index in all the single-spectra and dual-spectral ratio.
