FLUXX
Hyperspectral analysis workbench · Windows desktop
The full pipeline from raw cube to answer in one native app — explore, preprocess, reduce, unmix, detect, classify, and build machine-learning models. With a genuinely free Viewer. No IDL. No quote. No catch.
Free Viewer & paid Professional from one codebase · v1.0 · Windows 64-bit
Why FLUXX
FLUXX sits exactly on the incumbent's loudest complaints — cost, IDL dependence, learning curve, tool fragmentation — while undercutting on price and onboarding.
| Typical incumbent (ENVI) | FLUXX | |
|---|---|---|
| Pricing | Quote-only, commercial seats opaque | Free Viewer · transparent Professional |
| Scripting | Power lives in IDL | Native app, Python-based, no IDL |
| Analysis suite | Broad, but fragmented across add-ons | Reduce · unmix · detect · classify · ML in one app |
| Data & libraries | Bring your own | Built-in data browser — 19 datasets, one click |
| Current satellites | Retrofitted | First-class EMIT & Tanager ingest |
The analysis & ML suite
Breadth no generic image tool ships with — backed by the peer-reviewed literature behind every algorithm.
PCA, MNF, ICA, KernelPCA, NMF.
SMACC, PPI, N-FINDR, ATGP.
FCLS, NNLS, UCLS, LASSO.
ACE, MF, SAM, CEM, OSP, GLRT, AMSD — plus RX anomaly detection.
11 supervised and 7 unsupervised classifiers.
An embedded ModelZoo — train, compare, export, apply.
Standard mineral and vegetation indices.
Including QUAC — no ground truth required.
Dockable panels, 3D OpenGL spectral scatter, GIS basemap, multithreaded loading, in-dialog help.
A modern project structure — images, spectral libraries, and results in one tree, each result tagged with its source image, algorithm, and parameters.
Data & libraries
FLUXX ships with the GTA Spectral Data Browser — 19 ready-to-use datasets to download in one click: 12 hyperspectral images (AVIRIS, AVIRIS-NG, EMIT, EnMAP, HYDICE, ROSIS and more) and 7 spectral libraries totalling 30,000+ reference spectra (USGS, KLUM, ICRAF-ISRIC soils and more). Bring your own too — FLUXX loads, edits, and auto-resamples any ENVI library to your scene's wavelengths — and an External Resources tab links to NASA, USGS and JPL archives for millions more.
