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 Puhti, QGIS could be used for example to visualize the resulting files from other sources (lastools, R, python)

Available

QGIS is available in Puhti with following versions:

  • 3.22 in a singularity container: qgis(/3.22 = default) module
  • 3.16 in a singularity container: qgis/3.16 module

Usage

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. Start QGIS: Apps -> Desktop, choose Desktop: 'single application' and App: 'QGIS'
  3. QGIS is started automatically when the Desktop is launched.

Alternatively, especially if you want to use QGIS together with some other Graphical User Interface (GUI) tool or want to use data from Allas, QGIS can be started in Puhti web interface with remote desktop:

  1. Log in to Puhti web interface.
  2. Open Remote desktop: Apps -> Desktop, choose Desktop: mate or xfce.
  3. After launcing the remote desktop, double-click QGIS icon OR open Host Terminal (Desktop icon) and start QGIS:
module load qgis
qgis

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.

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.
