The geoh5py library was created for the manipulation and storage of a wide range of geoscientific data (points, curve, surface, 2D and 3D grids) in GEOH5 file format.
A free, powerful GEOH5 reader called Geoscience ANALYST is also available to display the contents of GEOH5 files as tables, charts, documents, maps, cross-sections, and 3D visualizations.
