About:
HDFView is a visual tool built in Java for browsing and editing HDF4 and HDF5 files. It provides a tree-based interface to navigate datasets, attributes, and groups within complex scientific data files. This tool simplifies data inspection and manipulation without requiring deep knowledge of the HDF libraries.

Key Features:

Graphical user interface for navigating HDF4 and HDF5 file structures
Support for viewing and editing datasets, attributes, and metadata
Cross-platform compatibility via Java
Data visualization capabilities for datasets

Use Cases:

Inspecting scientific data stored in HDF formats
Editing metadata and attributes in existing HDF files
Converting between HDF4 and HDF5 formats

Alternatives:

h5dump – Command-line tool for dumping HDF5 contents, lacks GUI
Panoply – NASA tool for visualizing HDF and NetCDF files, focuses on visualization over editing
