Using your own laptop or PC

We prefer using Free and Open Source Software because this enables you to install software on your own computer without paying for costly licenses, to learn and continue your work at home. In this course we use the LTR (long term release) Version QGIS 3.16.5.1 'Hannover'. QGIS is available on Windows, macOS, Linux and Android We recommend to use the QGIS Standalone Installer for Windows 64bit for this tutorial.
