From GIS to Remote Sensing
This post is about a minor update for the Semi-Automatic Classification Plugin for QGIS, version 5.0.13.
Following the changelog:
-interface translation to Polish (thanks to Robert Szczepanek and Jakub Pękala)
-Band calc added button to import expressions from a text file (each line an
expression) with name and expression separated by ";" such as NDVI; ( "#NIR#" -
"#RED#" ) / ( "#NIR#" + "#RED#" ) @NDVI
-Band calc added button to import expressions from a text file (each line an
expression) with name and expression separated by ";" such as NDVI; ( "#NIR#" -
"#RED#" ) / ( "#NIR#" + "#RED#" ) @NDVI
In this update the plugin interface has been translated to Polish. Many thanks to Jakub Pękala and Robert Szczepanek for their translation effort.
I invite you all to contribute to the translation of SCP and the documentation thereof to your language (see How to Get Involved).
Also, I have added a button in the tool Band calc for importing custom expressions in the Index calculation list. A text file can be imported containing an expression for each line; expressions must be in the form name; expression where the name is the expression name that is displayed in the list separated by ";" from the expression that is entered when it is selected in the list.
Simply create a text file, enter your expressions such as the following example.
NDVI; ( "#NIR#" - "#RED#" ) / ( "#NIR#" + "#RED#" ) @NDVI
EVI; 2.5 * ( "#NIR#" - "#RED#" ) / ( "#NIR#" + 6 * "#RED#" - 7.5 * "#BLUE#" + 1) @EVI
SR; ( "#NIR#" / "#RED#" ) @SR
Then open the text file from the tool Band calc. The expression should be available in the list.
