GRASS (Geographic Resources Analysis Support System) is a free Geographic Information System (GIS) software used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization.


GRASS is available in Puhti with following versions:

  • GRASS 7.4


In Puhti GRASS GIS is installed inside the QGIS singularity installation

It can be loaded with

module load qgis

After loading the module you can use the GRASS GIS graphical user interface from an interactive session with

sinteractive -i

You can also use the command line tools that come in GRASS. See the GRASS GIS manual for more information.

For GRASS commands to work in Puhti, you need to add singularity_wrapper exec before the GRASS commands.

For example printing the instructions for the command grass74

singularity_wrapper exec grass74 -h


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