Comparative Analysis of Selected Geostatistical Methods for Bottom Surface Modeling
Sensors, 2023 Digital bottom models are commonly used in many fields of human activity, such as navigation, harbor and offshore technologies, or environmental studies. In many cases, they are the basis for further analysis.

Machine-Learning-Method-Based Inversion of Shallow Bathymetric Maps Using ICESat-2 ATL03 Data
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023 The application of empirical methods for satellite-derived bathymetry is limited by the lack of in situ bathymetric data in remote, inaccessible areas.

On the effect of random errors in gridded bathymetric compilations [PDF]
, 2002 We address the problem of compiling bathymetric data sets with heterogeneous coverage and a range of data measurement accuracies. To generate a regularly spaced grid, we are obliged to interpolate sparse data; our objective here is to augment this ...

The Use of an Artificial Neural Network to Process Hydrographic Big Data during Surface Modeling
Computers, 2019 At the present time, spatial data are often acquired using varied remote sensing sensors and systems, which produce big data sets. One significant product from these data is a digital model of geographical surfaces, including the surface of the sea floor.

The International Bathymetric Chart of the Arctic Ocean (IBCAO) Version 3.0 [PDF]
, 2012 [1] The International Bathymetric Chart of the Arctic Ocean (IBCAO) released its first gridded bathymetric compilation in 1999. The IBCAO bathymetric portrayals have since supported a wide range of Arctic science activities, for example, by providing ...

CHS Bathymetric Data Warehouse
Canadian Journal of Remote Sensing, 1998 RESUMELe Service hydrographique du Canada (SHC) a adopte les systemes de collecte de donnees bathymetriques numeriques a faisceaux multiples permettant une couverture du fond marin a 100%. L'utilisation de ces nouvelles technologies de collecte de donnees a entraine un accroissement considerable du volume, en termes de multi-teraoctets, des donnees ...
