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)
QGIS is available in Puhti with following versions:
- 3.8.1 Zanzibar via conda
Using QGIS with graphical user interface
QGIS is included in the geoconda module and can be loaded with
module load geoconda
If you have connected with a ssh connection that has X11 forwarding enabled, you can launch a graphical user interface with
For X11 forwarding to be enabled you need to install a suitable program for your own computer first (unless you are using Linux or Mac). You can read instructions how to do that here
It is also possible to access QGIS functionalities from Python without an graphical user interface with the PyQGIS library
Do not run long CPU intensive jobs on the login nodes! This means you can't run computationally intensive analysis on graphical user interfaces on Puhti until interactive Puhti-shells are made available later in 2019. Use the batch job system on Puhti or run analysis on taito-shell.
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.
