Minor Update: Semi-Automatic Classification Plugin v. 3.0.9

This post is about a minor update for the Semi-Automatic Classification Plugin for QGIS, version 3.0.9.

Following the changelog:
-fixed little bug of the land cover change calculation
-new message if ROI has singular covariance matrix

This update fixes a minor issue during the calculation of the land cover change.
In addition, a new message inform the user when the spectral signature of a ROI has a singular covariance matrix, which can happen if the ROI is too small or pixels have all the same value. This is a problem only when using the Maximum Likelihood algorithm (i.e. the spectral signature is not used).
The updated version is already available for download.

Attention: from version 3.0.7 I changed the default names of the training shapefile fields, for consistency. If you need to use a shapefile with old names, simply change the field names in the tab Settings.
