.kven (File Format)

The ’.kven' file format is a data storage format based on the HDF5 standard, designed specifically for seismic and ground-penetrating radar (GPR) data. It was developed by Géostack Inc., a Canadian geophysical software company, for use within its SeisMate software platform.

Overview

The `.kven` format uses a hierarchical structure to store complex geophysical datasets efficiently. It is intended to simplify the management of seismic and GPR data, including acquisition parameters, survey metadata, and processed results.

Typical contents include:

• **Acquisition Parameters**: sampling rates, source types, receiver arrays
• **Raw and Processed Data**: seismic traces, shot gathers, migrated images
• **Survey Metadata**: coordinate systems, equipment specifications, field logs

Compression and chunking features provided by the HDF5 framework are utilized to optimize the performance of large datasets.

Applications

The `.kven` format is used in various applications, including:

• Infrastructure monitoring
• Environmental and engineering geophysics
• Academic research in seismology and near-surface imaging

History

The `.kven` file format was first introduced in 2021 to address the limitations of traditional seismic data formats, particularly regarding metadata flexibility, portability, and long-term data preservation.
