Installation (Dev)


The EnMAP-Box 3 is a QGIS plugin and therefore uses the Python distribution that is delivered with or linked into QGIS. If you like to use an Integrated Development Environment (IDE) to develop and debug python applications for the EnMAP-Box, or in general QGIS, we recommend that your IDE runs under the same environmental settings as your QGIS does.

The following sections describe which settings are needed to run and debug the EnMAP-Box from inside an IDE without the need to start a heavy QGIS instance.

We mainly tested in for the PyCharm IDE and it worked well on PyDev, too.

To setup your IDE for developing EnMAP-Box Applications, you need to:

  1. Clone the EnMAP-Box git repository and add it to your project sources

  2. Start your IDE using the same environmental settings as QGIS

  3. Set the QGIS python as python interpreter of your project

  4. Ensure that all python packages your application depends on are accessible in your QGIS python and your IDE (Install python packages (if required)):

    • gdal, numpy, scipy, scikit-learn
    • pyqtgraph, matplotlib
    • sphinx and the sphinx-rtd-theme fro documentation
  5. Start the EnMAP-Box from your IDE (Start the EnMAP-Box)


The following description is based on

QGIS for Windows is based on an OSGeo4W installation that uses a set of cascading batch (*.bat) files to setup the QGIS environment. We use a similar approach to start the IDE.

  1. First, locate the root folder of your QGIS3/OSGeo4W installation, e.g. C:\Program Files\QGIS 3.0\ or C:\Program Files\OSGeo4W\
  2. Create a start_IDE_with_QGIS.bat to start your IDE in the same QGIS environment:
::STARTUP Script to start a IDE like PyCharm under the same environment as QGIS
::OSGeo4W or QQGIS installation folder
set OSGEO4W_ROOT="C:\Program Files\QGIS 3.0"

::Executable of your IDE
set IDE="C:\Program Files\JetBrains\PyCharm 2017.3.4\bin\pycharm64.exe"

::set defaults, clean path, load OSGeo4W modules (incrementally)
call %OSGEO4W_ROOT%\bin\o4w_env.bat
call qt5_env.bat
call py3_env.bat

::lines taken from python-qgis.bat

::make git and git-lfs accessible
set PATH=%PATH%;C:\Users\geo_beja\AppData\Local\Programs\Git\bin
set PATH=%PATH%;C:\Users\geo_beja\AppData\Local\Programs\Git LFS

::make PyQGIS packages available to Python

:: GDAL Configuration (
:: Set VSI cache to be used as buffer, see #6448 and
set VSI_CACHE_SIZE=1000000
set QT_PLUGIN_PATH=%OSGEO4W_ROOT%\apps\qgis\qtplugins;%OSGEO4W_ROOT%\apps\qt5\plugins


start "Start your IDE aware of QGIS" /B %IDE% %*

::uncomment the following lines to start the Qt Designer, Assistent or QGIS 3 as well
::start "Start Qt Designer" /B designer
::start "Start Qt Assistant" /B assistant
::start "Start QGIS" /B "%OSGEO4W_ROOT%\bin\qgis-bin.exe" %*

::uncomment the following lines to open the OSGeo4W Shell
::@echo on
::@if [%1]==[] (echo run o-help for a list of available commands & cmd.exe /k) else (cmd /c "%*")

Note the lines to extend PATH by locations of local Git executables. This might be required to enable your IDE to access the git and git-lfs executables.

set PATH=%PATH%;C:\Users\geo_beja\AppData\Local\Programs\Git\bin
set PATH=%PATH%;C:\Users\geo_beja\AppData\Local\Programs\Git LFS

You can start Qt development tools with:

start "Start Qt Designer" /B designer
start "Start Qt Assistant" /B assistant
start "Start QGIS" /B "%OSGEO4W_ROOT%\bin\qgis-bin.exe" %*
  1. Call start_IDE_with_QGIS.bat to start your IDE and create a new project.

    Open the project settings and select the C:\Program Files\QGIS 3.0\bin\python3.exe as project interpreter.

  2. Finally add the following locations to your project:

Start the EnMAP-Box

If everything is set up correctly, you should be able to start the EnMAP-Box using this Python script:

if __name__ == '__main__':

    from enmapbox.gui.utils import initQgisApplication
    from enmapbox.gui.enmapboxgui import EnMAPBox

    qgsApp = initQgisApplication()
    enmapBox = EnMAPBox(None)


Build the EnMAP-Box Plugin for QGIS

The make folder contains some helper scripts required to build (parts) of the EnMAP-Box Plugin:

make/ - create the EnMAP-Box Plugin ZIP file make/ - routines to handle PyQt5 issues, e.g. to create the Qt resource files make/ - a widget to show Qt internal QIcons and to copy its resource path to the clipboard make/ - update parts of the EnMAP-Box code which are hosted in external repositories

If you like to build and install the EnMAP-Box Plugin from repository code you need to run the build() function in
