A unified hyperspectral imaging data format for cloud-based analysis and visualization

We propose a new hyperspectral imaging data format based on the ENVI¹ standard, enhanced for cloud-based applications. The format centralizes metadata in an extended ENVI header and supports diverse auxiliary files for ML, calibration, and visualization. It is packaged in an uncompressed ZIP container for robust data exchange and internally supports optional advanced compression algorithms. We discuss tools and use cases, harmonization with the new IEEE 4001 standard and prepare integration in a cloud-based spectral data processing infrastructure.
