laspectools

laspectools is a Python package for efficient data reduction of ELEMISSION Laser-induced Breakdown Spectroscopy (LIBS) hyperspectral imaging data.

laspectools reads Elemission ELE binary files containing hyperspectral imagery, and reduces these spectral images to elemental bands. These can be subsequently used as proxies for elemental imaging or combined to generate estimates of mineralogical speciation, composition and distribution. The package is largely built around xarray data structures internally, and uses Zarr archives as the as an interoperable output format - it natively supports multidimensional gridded data/imagery, subindexing for subsequent viewing/processing, and works well with cloud storage solutions.
