MESMA (Multiple Endmember Spectral Mixture Analysis) is a common unmixing technique in the fieldof remote sensing. This suite of processing tools allows you to unmix your image with MESMA (with multi-level fusion, stable zone unmixing, ...) and post-process the MESMA results (visualisation tool, shade normalisation, soft to hard classification).

MESMA is both a QGIS plugin and stand-alone python package that implements the MESMA (Multiple Endmember Spectral Mixture Analysis) unmixing algorithm in the field of Remote Sensing.

It is based on VIPER Tools: a software package 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 Tool and MESMA.

Spectral Library Tool provides the following:

• Creating spectral libraries interactively (selecting spectra from an image or using regions of interest) and managing the metadata (developed by HU Berlin)

• Optimizing spectral libraries with Iterative Endmember Selection, Ear-Masa-Cob or CRES

• Website: <https://spectral-libraries.readthedocs.io>

• Repository: https://bitbucket.org/kul-reseco/spectral-libraries

MESMA provides the following:

• Running SMA and MESMA (with multi-level fusion, stable zone unmixing, …)

• Post-processing of the MESMA results (visualisation tool, shade normalisation, …)

• Website: <https://mesma.readthedocs.io>

• Repository: https://bitbucket.org/kul-reseco/mesma

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