Hyperspectral remote sensing provides detailed information on the Earth's surface by capturing hundreds of contiguous, narrow spectral bands in the VNIR and SWIR ranges. This spectral richness allows scientists to analyze vegetation, water quality, soil properties, and many other environmental variables with unprecedented accuracy.
Launched in 2019 by the Italian Space Agency (ASI), PRecursore IperSpettrale della Missione Applicativa (PRISMA) is a spaceborne mission that delivers medium-resolution high-quality hyperspectral imagery (30m) combined with a panchromatic channel (5m). PRISMA products are distributed in multiple levels (L2B, L2C, L2D) and have become a key dataset for applications in agriculture, forestry, inland and coastal waters, geology, and climate studies.
With prismatools, researchers can explore PRISMA imagery interactively, extract meaningful biophysical information, and integrate the data into broader geospatial workflows.
- 📂 Read and Write PRISMA hyperspectral and panchromatic L2 products (L2D, L2B, L2C)
- 🎨 Visualize PRISMA data interactively (2D maps, RGB composites, custom band combinations)
- 📊 Analyze hyperspectral imagery (band math, vegetation indices, PCA)
- 🌍 Extract and plot spectral signatures from any pixel or region of interest
- 💾 Export spectral signatures as CSV files
- 🧩 Integrate seamlessly with popular Python libraries (xarray, rasterio, geopandas, matplotlib)
