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:
- 3.34 in Puhti, includes also GDAL, PDAL and the new native point cloud tools in QGIS.
- 3.31 in Puhti and LUMI, includes also GDAL, GrassGIS, PDAL and SagaGIS.
- 3.22 in Puhti
Usage
QGIS in Puhti
For using QGIS, open it in Puhti web interface:
- Log in to Puhti web interface.
- Open Desktop app.
- After launching the Desktop, double-click QGIS icon for the newest version.
If you want to use older version, open 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 Using geospatial files directly from cloud, inc Allas tutorial and then start QGIS from Terminal.
With large quantities of data in Allas, consider using virtual rasters.

Installation
- 3.34 was installed Tykky's conda-containerize functionality. The .yml file included only
qgis
package fromconda-forge
repository. - 3.31 was installed Tykky's wrap-container functionality using the QGIS Docker image from Dockerhub provided by QGIS community. In LUMI
Tykky
is namedContainer wrapper
.
wrap-container -w /usr/bin docker://qgis/qgis:latest --prefix install_dir
