Version:  Semi-Automatic Classification Plugin 4.1.1
4.1.1 Minor update: -fixed issue with signature thresholds 4.1.0 Major update: -added tab for classification threshold for individual signatures -added tab for the definition of band weight for algorithms -tab reclassification allows for decimal values of raster 4.0.1 Minor update: -fixed issue that prevented Landsat conversion of thermal bands 4.0.0 New version: -new Band calculator for raster operations using NumPy functions -new Landsat pre processing tab for editing metadata and option for creating band set -new option for showing / hiding previews -new SCP menu in the main menu bar -enhanced the Maximum Likelihood algorithm which is now considerably faster -temporary ROI are displayed as overlay (rubber band) with a + symbol on clicked pixel -new option to hide and show the temporary ROIs -in ROI dock new option for refreshing automatically the temporary ROI while changing ROI parameters -in ROI dock new option for automatic plot of temporary ROI -new option for displaying over the region growing cursor vegetation indexes such as NDVI and EVI (the latter only for images converted to reflectance) -new function for displaying the pixel spectral signature with right click on map using ROI pointer -new combo box in SCP toolbar for quickly displaying RGB color composites (e.g. RGB=432 or RGB=4,3,2 or RGB=4;3;2 or RGB=4-3-2) of input image (and automatic creation of a virtual raster for band set) -now the window spectral signature plot allows for the display of signature values in table and calculation of signature distances (separability) -new tool Split in Pre processing tab for splitting raster bands -new tool Convert classification to vector in Post processing tab for creating a classification shapefile -new tool Reclassification in Post processing tab for the easy reclassification from Class ID to Macroclass ID and Python expressions are allowed in the definition (e.g. raster < 3) -enhanced function Clip multiple rasters -new reset button for resetting the signature list file -new button in the classification dock for merging spectral signatures obtaining a new one calculated as the average of signature values (without covariance matrix) -now classes or macroclasses having ID = 0 are allowed and classified as 0 (unclassified) in the output which is useful for creating masks for classes -in the signature list it is possible to set the color of multiple selected signatures at once (pressing shift and double click on a color) and check/uncheck all with a double click on the checkbox column (S) -new function (right click with classification preview pointer) displays the algorithm raster of the preview (a raster where every pixel has the value calculated by the algorithm for the class assigned to the pixel thereof) useful for assessing spectral signatures (black pixels are distant from the spectral signatures and white pixels are closer to the spectral signatures) -now a classification style (.qml file) is saved along with the classification output allowing for displaying classification colors when loading the classification in new qgis projects -new buttons in tab Band set for exporting the band set to virtual raster or stacked raster (a multi-band .tif file) -now the signature file path is stored in the project as absolute or relative path according to QGIS project settings -in Settings added an option for the creation of virtual rasters for certain temporary data (which saves disk space) -new button in Debug for testing SCP dependencies -several bugs corrected 3.1.6 Minor update: -fixed Mac
