GeoLibre now supports interactive 3D hyperspectral image cubes

[giswqs]

GeoLibre now supports interactive 3D hyperspectral image cubes directly in your web browser. No server required.

You can now open NetCDF and HDF5 hyperspectral datasets in GeoLibre and explore them as fully interactive 3D image cubes, all running locally in the browser.

Simply go to Add Data → NetCDF / HDF, then open Style → 3D Cube to:

• Load only what you need. Read the current map view, draw a custom area of interest, or load the entire scene.
• Create true-color or false-color composites. Select any three bands and display them on the top face of the cube.
• Explore the spectral dimension. Interactively move a slicing plane through the cube to reveal internal structures.
• Customize the visualization. Apply different colormaps, adjust vertical exaggeration, and freely rotate and inspect the cube in 3D.

GeoLibre also lets you perform interactive spectral analysis. Click any pixel to instantly plot its spectral signature. Sampled locations remain highlighted on the map with matching colors, making it easy to compare vegetation, water, bare soil, and other land cover types. Charts can be opened in a separate window and exported as PNG or CSV.

Everything runs entirely client-side. NetCDF and HDF5 files are decoded in the browser using WebAssembly, while remote datasets are accessed efficiently through HTTP range requests, so even multi-gigabyte hyperspectral cubes can be explored without downloading the entire file.
