HSI Studio — Free In-Browser Hyperspectral Image Viewer & Analysis Interface

HSI Studio is a free, high-performance web tool to upload, visualize, and analyze hyperspectral datacubes directly in your browser. Zero installation required. 100% private and client-side—your data never leaves your machine.

Supported Hyperspectral Formats

• ENVI Header & Binary (.hdr, .dat, .raw, .bil, .bip, .bsq)
• NumPy Compressed Archives (.npz, .npy)
• MATLAB Datasets (.mat)
• TIFF & Multi-Page GeoTIFF (.tif, .tiff)
• CSV Spectral Libraries with wavelength calibration
• Built-in Benchmark Datasets (Indian Pines, Salinas Scene, Hyperleaf 2024)

Key Analysis & Visualization Features

• Interactive Spectral Profiler: Click anywhere on the datacube to extract reflectance curves across all bands with high-resolution graph exports.
• Principal Component Analysis (PCA): Compute eigenvectors and eigenvalues to reduce spectral dimensionality and isolate variance across datacubes.
• K-Means Unsupervised Clustering: Segment materials, land cover, crops, or minerals automatically by spectral similarity.
• Custom Band Math & Derived Indices: Calculate NDVI, NDRE, EVI, band ratios, and custom algebraic formulas in real-time.
• RGB & False-Color Composites: Generate True Color (RGB), Near-Infrared (NIR), Short-Wave Infrared (SWIR), and custom false-color band renderings.
• Magic Wand & ROI Extraction: Select continuous regions of interest by spectral tolerance and batch-export spectral signatures.
• Machine Learning Hub: Train Partial Least Squares (PLS) regression and Random Forest classification models on hyperspectral data.
• Kaggle Integration: Connect directly to Kaggle datasets to sync, stage, and analyze hyperspectral imagery.
