Processing Algorithms

Usage

Processing Toolbox

Open the Processing Toolbox: Processing > Toolbox or press Ctrl + Alt + T.
Search the name of the Algorithm in the search bar or scroll down and click on EnMAP-Box and a drop down of all algorithms will appear.
The dialog box will appear once you double-click on the algorithm you want to use.
Now fill the parameters, inputs and output locations and Click on run.

Model Designer

Open Model Designer: Processing > Graphical Modeler or press Ctrl + Alt + G.
Load your model in the it and to incorporate EnMAP-Box Algorithms click on the Algorithms tab.
Scroll down and click on EnMAP-Box from the list , drop down list with all the algorithms will appear.
Select and drag the algorithm you want into your model. A dialog box will appear, adjust the input and parameters according to your needs and click OK.

Python Console

QGIS installed (with EnMAP-Box plugin installed).
The EnMAP-Box plugin is activated (under Plugins > Manage and Install Plugins).
The processing module is imported.
import processing
You’re familiar with the names of the algorithms or can find them using the command below.
Once you know the algorithm ID (like enmapbox:Build3DCube), you can get help like this:
processing.algorithmHelp("enmapbox:Build3DCube")
You can obtain the Python command for any algorithm by opening its dialog box, clicking the Advanced button, and selecting Copy as Python Command.

Use the copied function to run the algorithm:

processing.run("enmapbox:Build3DCube", {
'raster':'C:/Users/Aryan/AppData/Roaming/QGIS/QGIS3/profiles/default/python/plugins/enmapboxplugin/enmapbox/exampledata/enmap_potsdam.tif',
'spectralScale':1,'dx':1,'dy':1,
'outputCubeFace':'TEMPORARY_OUTPUT',
'outputCubeSide':'TEMPORARY_OUTPUT'
})

You need to adjust the parameters according to the algorithm’s needs. Paths can be to files on disk or to in-memory layers.

Command Line Usage

Open your conda prompt and activate the enmapbox.
You can obtain the Command line code for any algorithm by opening its dialog box, clicking the Advanced button, and selecting Copy as Python Command.

Use the copied function to run the algorithm:

qgis_process run enmapbox:Build3DCube --distance_units=meters --area_units=m2 --ellipsoid=EPSG:7030 --raster='C:/Users/Aryan/AppData/Roaming/QGIS/QGIS3/profiles/default/python/plugins/enmapboxplugin/enmapbox/exampledata/enmap_potsdam.tif' --spectralScale=1 --dx=1 --dy=1 --outputCubeFace=TEMPORARY_OUTPUT --outputCubeSide=TEMPORARY_OUTPUT

You need to adjust the parameters according to the algorithm’s needs. Paths can be to files on disk or to in-memory layers.
