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. Here are the links to download the software from the internet and install it yourself:

QGIS http://www.qgis.org/en/site/forusers/download.html, available for Windows, Mac OSX, Linux and Android. If you want to follow the exercises of this tutorial on Windows, we recommend following the

Installation Guide for Windows

  1. Determine if your Windows is 32bit or 64bit Version. Knowing this information is important because you need to choose the right software so its performance can be optimized.
    • If you are using Windows 8: On the Start Screen, press Win key (Windows logo key) and the x letter simultanously. Notice the menu of administrative tools in the lower-left corner of the screen, click System and view the information on system type.
    • If you are using Windows 7: Press Win key (Windows logo key), Control panel --> System and Security --> System and view the information on system type.
  1. Download the OSGeo4W Network Installer 32bit for Windows 32-bit or OSGeo4W Network Installer 64bit for Windows 64-bit and save the file into a temporary folder.
  2. Start the OSGeo4W Setup Program with a double click the on the downloaded file osgeo4w-setup-x86.exe.
  3. Choose Advanced Installation. Next.

  10. Install additional packages: Type into the Search field "otb-bin". click on the + symbol before "Libs" to extend the folder. Click on the "Skip" symbol before "otb-bin"..
    QGis Setup select packages.png
  11. Go on, accept the licence agreements and wait until all programs are installed.Next.
  12. Start QGIS by Start|All programs|OSGeo4W|QGIS Desktop.


info.png Updating QGIS
Updating QGIS is easily done by using All Programs --> OSGeo4W --> Setup or by double clicking the file C:\OSGeo4W\bin\osgeo4w-setup.exe. Follow the advanced installation procedure. New package versions will be automatically detected. Accept all previous settings and wait until all updated programs are installed.


info.png Uninstalling QGIS
To deinstall QGIS you simply delete the installation folder, which is C:\OSGeo4W, the settings folder C:\Users\YourName\.qgis2 and the related icons on the Desktop.

Trying Linux? Tux.png

If you are interested to try a Linux OS on your own Windows C, we recommend to install the current distribution of Ubuntu. You can install Ubuntu onto a computer alongside a copy of Windows. You will be able to select whether to start Ubuntu or Windows each time your computer starts up or you can try to run Ubuntu on a CD or even on a memory stick alongside your current system.

Configuration

Language settings

Go to Settings --> Options --> Locale and click the checkbox Override system locale on. You may choose one of 42 languages which are available for QGIS instead the system locale. For our course please select english (en_US). The settings are active after restarting QGIS.

Display settings

In QGIS 2.8 the rendering speed of displaying large image data is much improved using multi-threading. This option is not enabled by default. Go to Settings --> Options --> Rendering and click the checkbox Render layers in parallel using many CPU cores on. Zooming and moving layers is much faster then.

Processing Toolbox

The spatial processing framework is a highlight of QGIS. It is based on the python plugin SEXTANTE coded by Victor Olaya which integrates a large number of analysis algorithms from different open source projects.

The plugin functions are activated by default and can be found under the main menu Processing --> Toolbox. A Processing Toolbox Window should be opened on the right side of the GUI. On the bottom of this window find the droplist button Simplified interface. Please switch to Advanced interface.

If you followed the guides for QGIS installation and R installation on Windows new software versions of GDAL, OTB, GRASS GIS and SAGA are already installed and correctly configured for the Processing Toolbox.

To make use of the spatial R interface go to Processing --> Options and configuration --> Providers --> R scripts. Switch Activate on and change the R Folder to C:\OSGeo4W\bin\apps\R\R-3.2.3 or to another folder name with user write access where you installed your current R version. Activate Use 64 bit version if you use on a 64-bit Windows system. Check the version of your Windows OS using the start menu Control Panel --> System and Security --> System.
