Additional hyperspectral datasets to explore beyond Wyvern, including NASA AVIRIS / AVIRIS-NG, Germany's EnMAP mission, and the NEON airborne observatory.

An overview of common geospatial and hyperspectral tools — QGIS, ArcGIS, ENVI, Python, R, and GDAL — to help you choose software for analyzing Wyvern imagery.

Geospatial fundamentals for earth observation: the difference between vector and raster data, common file formats, and how they are used with Wyvern hyperspectral imagery.

An introduction to hyperspectral imaging: the electromagnetic spectrum, and how panchromatic, multispectral, and hyperspectral earth observation imagery differ.

Hyperspectral image formats explained: the data cube concept and common raster formats including GeoTIFF, ENVI, and HDF5 used to store hyperspectral imagery.

Material reflectance spectral libraries for hyperspectral analysis, including the USGS Spectral Library, Reading's urban surfaces library, and the ECOSTRESS Spectral Library.

How hyperspectral indices measure plant health — chlorophyll, carotenoids, and leaf area — using narrowband indices like RENDVI and VREI2 on Wyvern Dragonette imagery.

Understand the SpatioTemporal Asset Catalog (STAC) — items, catalogs, and collections — why Wyvern uses STAC to deliver imagery, and tools like PySTAC for accessing it.
