Installation in Windows 64 bit

QGIS download and installation

• Download the latest QGIS version 64 bit from here ;
• Execute the QGIS installer with administrative rights, accepting the default configuration.

Now, QGIS is installed.

Installation of required dependencies

The Semi-Automatic Classification Plugin requires Remotior Sensus, GDAL, NumPy and SciPy for most functionalities. Optionally, scikit-learn and PyTorch are required for machine learning.

Therefore, we need to install the dependencies that are not included in the QGIS installation.

• Close QGIS;
• From the Start menu, open OSGeo4W Shell (administrative rights may be required);

• Enter the following command:

pip3 install --upgrade remotior-sensus scikit-learn torch

Follow the same procedure for updating the dependencies.

Tip

In case of issues please read :ref:`installation_conda`.

Semi-Automatic Classification Plugin installation

• Run QGIS;
• From the main menu, select Plugins > Manage and Install Plugins;

• From the menu All, select the Semi-Automatic Classification Plugin and click the button Install plugin;

• The SCP should be automatically activated; however, be sure that the Semi-Automatic Classification Plugin is checked in the menu Installed (the restart of QGIS could be necessary to complete the SCP installation);

Configuration of the plugin

Now, the Semi-Automatic Classification Plugin is installed and a dock and a toolbar should be added to QGIS. Also, a SCP menu is available in the Menu Bar of QGIS. It is possible to move the toolbar and the dock according to your needs, as in the following image.

The configuration of available RAM is recommended in order to reduce the processing time. From the :ref:`SCP_menu` select Settings > Processing .

In the :ref:`settings_tab`, set the Available RAM (MB) to a value that should be half of the system RAM. For instance, if your system has 2GB of RAM, set the value to 1024MB.

Update of required dependencies

The dependency Remotior Sensus is frequently updated. The Semi-Automatic Classification Plugin can check automatically if a new version is available, and display a message in the :ref:`scp_dock`.

It is recommended to close QGIS and update Remotior Sensus following the same installation steps described in :ref:`installation_dependencies_win64bit` .
