Hyperspectral Imaging¶
Analyse Spectra¶
This module allows for a user to select a spectrum from a dataset, and compare it with library spectra. Different features can be highlighted, and a hull can be removed from the spectrum. This tool is essentially a viewer, allowing for the user to strategize interpretation strategies.
Options are:
Display band – choice of which data wavelength to display.
Feature – highlight a standard spectral feature.
Rotate view – Allows a dataset to be rotated for display purposes.
Remove hull – allows for the hull removed representation of a spectrum.
Load ENVI spectral library. This can be any spectral library in ENVI spectral library format. The user then chooses the appropriate reference spectrum to compare with.

Process Features¶
This module takes as input hyperspectral data, and allows for a standard set of feature definitions to be calculated (Haest et al. 2012). Currently this includes mica, spectate, kaolin, chlorine, epidote and ferrous iron. Once a product is selected, the details of the various datasets which make up the calculation are shown on a table, including feature name, filter, threshold and description. The user is able to alter details such as the respective dataset threshold.
