Mapping bathymetry with satellite-based imagery for optically shallow waters is important for the management of coastal areas. However, mapping ultrahigh-spatial-resolution bathymetry (spatial resolution < 5 m) for a wide range of coastal optically ...

IEEE Transactions on Geoscience and Remote Sensing, 2022
Acoustic remote sensing with multibeam echo-sounder systems (MBESs) has been extensively used for coastal and ocean survey works. The imperfect integration of multibeam echo sounder and motion sensor can introduce integration errors, which manifest as ...

A Real-Time Data Acquisition System for Single-Band Bathymetric LiDAR
IEEE Transactions on Geoscience and Remote Sensing, 2023Bathymetric light detection and ranging (LiDAR), which uses a laser with narrow pulsewidth and a high repetition rate, requires a real-time data acquisition system (RTDAQS) for quickly transmitting data with the characteristic of high sampling rates ...

Haptic visualization of bathymetric data
2012 IEEE Haptics Symposium (HAPTICS), 2012Visualization of water depth in geographical maps is limited by contour line density and by human ability to distinguish a subtle difference of the color gradient at a specific map scale. We were interested in whether it is it possible to increase the accuracy of subjective assessment of the bathymetric information coded by color intensity when visual ...

Bayesian sunken oil tracking with SOSim v2: Inference from field and bathymetric data.
Marine Pollution Bulletin, 2021Sunken oil is often difficult to detect, and few oil spill models are designed to locate and track such oil. Therefore, the multi-modal Bayesian inferential sunken oil model, SOSim (Subsurface Oil Simulator), was expanded in this work for use during ...

Integrating bathymetric and topographic data
AIP Conference Proceedings, 2017The quality of bathymetric and topographic resolution significantly affect the accuracy of tsunami run-up and inundation simulation. However, high resolution gridded bathymetric and topographic data sets for Malaysia are not freely available online. It is desirable to have seamless integration of high resolution bathymetric and topographic data.

SPOT satellite data analysis for bathymetric mapping
Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2002This paper presents the determination of bathymetric maps from the analysis of multispectral SPOT images. To this end, we have developed a multispectral segmentation method based on a hierarchical Markovian modeling including the unsupervised estimation of the model parameters.

Compression of bathymetric data using wavelets
IEEE Pacific Rim Conference on Communications, Computers, and Signal Processing. Proceedings, 2002The compression of bathymetric data using three different types of wavelet transforms as well as the discrete cosine transform (DCT) is considered. The various compression schemes are then compared with respect to the compression ratios achieved, computational complexity, and accuracy of reproduction.

Multibeam bathymetric data at NOAA/NGDC
Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600), 2005Multibeam bathymetry is being collected in exponentially increasing quantities, which are expected to be tens of terabytes per year in the near future. The National Geophysical Data Center (NGDC) is the national and international steward of marine geophysical data, including multibeam bathymetry, and has developed a MultiBeam Bathymetric Data Base ...
