rioxarray / xarray remain useful optional analysis companions for reading ENVI outputs in notebooks, but they are not declared as direct runtime package dependencies.

pip install -e .

The source-install commands assume you have cloned earthlab/spectralbridge and changed into its directory. The distribution name is earthlab-spectralbridge, but no PyPI project was exposed at that name in the 19 October 2026 audit. See the beginner path for setup and a tiny offline example.
