hydrography

Delaunay and Constrained Delaunay Triangulations in Java, providing high-performance utilities for modeling surfaces with support for Lidar LAS files, Digital Elevation Models (DEM), finite element analysis, path planning, natural neighbor interpolation, and other applications of Triangulated Irregular Networks (TIN)

Fast methods to work with hydro- and topography data in pure Python.

A curated list of public available resources for the ocean mapping community

A package for sound speed profiles

Bathymetrix-AI is a professional QGIS research toolkit for high-precision Satellite-Derived Bathymetry (SDB). The toolkit integrates multispectral satellite imagery with ICESat-2 (ATL24) LiDAR bathymetry through a modular and adaptive Machine Learning framework.

Libraries for manipulating S-100 based nautical charts.

TypeScript parser for S-57 and S-101 marine nautical charts with S-52 symbology rendering

Tool based on Python and Jupyter Notebook for interactive processing of Kongsberg MBES bathymetry and backscatter data.

Cartographic Sounding Selection for ENCs

Data analysis code used for Wallace et al. (2018): Multi-decadal trends and variability in temperature and salinity in the Mid-Atlantic Bight, Georges Bank, and Gulf of Maine

Tools for navigationally safe bathymetric surface processing - Rolling Coin algorithm, iterative Laplacian smoothing, shoal buffering and surface offsetting. Efficient implementations written in C. Simple command-line interface to support scripting use.

This project shares CHS's development pipeline for CSB data processing in Canadian waters. Several data formats are supported, including the one from IHO DCDB. The reduction for water levels is based on predictions/observations automatically extracted from the CHS Integrated Water Level System (IWLS).
