Project description

About The Spectral Library Tool

The Spectral Library Tool software package is both a QGIS plugin and stand-alone python package that provides a suite of processing tools for multi- and hyperspectral spectral libraries.

The software is based on VIPER Tools: code written for ENVI/IDL and released in 2007. Several updates have been released since and now it has been ported to PyQGIS in the period 2017 - 2020. The original VIPER Tools is now split over two python/QGIS tools: Spectral Library Tools and MESMA.

Spectral Library Tool provides the following:
MESMA provides the following:

The software has now been developed in the open source environment to encourage further development of the tool.

What is new in the MESMA tool 1.0?

Differences between Viper Tools 2.0 and the MESMA tool 1.0:
  • The migration to PyQGIS is not just a translation from IDL to Python, but also a serious re-write of the code and a revision of the GUI to match the look and feel of other QGIS tools.
  • The output of the MESMA tools has been optimized, breaking backwards compatibility with the IDL tools.
  • A tool for visualisation of the MESMA results has been introduced. A first draft of this tool had been proposed for Viper 2.0, however this was not yet user-friendly and therefore later removed again. The visualisation tool included in this version is a revision of the former tool, with a focus on user friendliness and GIS.
  • The post-processing tool for integration with DEM has been removed.
  • Extra post-processing tool: Soft to Hard Classification (transforms the fractions image into a classification image)
