QGIS

QGIS is a free and open source GIS application that can be used for viewing, editing and analysing geospatial data. QGIS supports a very wide range of vector and raster formats and also common API protocols like WMS, WMTS, WCS and WFS.

In supercomputers, QGIS could be used for example to visualize the resulting files from processing with other tools: lastools, R, Python etc.

Available

QGIS is available with following versions:

Usage

QGIS in Puhti

The easiest option for using QGIS is to open it in Puhti web interface as Desktop app.

  1. Log in to Puhti web interface.
  2. Open Remote desktop: Apps -> Desktop, choose Desktop: xfce.
  3. After launcing the remote desktop, double-click QGIS icon for the newest version.

If you want to use older version, open Host Terminal (Desktop icon) and start QGIS:

module load qgis/3.22
qgis

QGIS in LUMI

Until LUMI web interface is available, QGIS needs to be used with SSH X11 forwarding.

module use /appl/local/csc/modulefiles
module load qgis
qgis

SagaGIS toolbox in QGIS

SagaGIS tools are not available by default with QGIS 3.31 in Processing Toolbox, but can be added with installing Saga Next Gen plug-in. This is a new plug-in and all tools might not work yet.

PyQGIS

It is also possible to access QGIS functionalities from Python without an graphical user interface with the PyQGIS library. Use python3 for accessing PyQGIS libraries.

Puhti QGIS and Allas

QGIS can read files directly from Allas, either using S3 or SWIFT API. Before starting QGIS set up the connection as described in on GDAL page.
