QGIS

QGIS is a free and open source GIS application that can be used for viewing, editing and analysising 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, grass, python)

Available

QGIS is available in Puhti with following versions:

  • 3.14 via conda in geoconda-3.8
  • 3.10 via conda in geoconda-3.7

Usage

Using QGIS with graphical user interface

QGIS is included in the geoconda module and can be loaded with

module load geoconda

If you are using NoMachine or have connected with a ssh connection that has X11 forwarding enabled, you can launch a graphical user interface with

qgis

Note

The recommended way of using graphical interfaces in Puhti is through NoMachine and an interactive batch job

It is also possible to access QGIS functionalities from Python without an graphical user interface with the PyQGIS library

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.
