Saga GIS (System for Automated Geoscientific Analyses) is a GIS application for spatial data editing and GIS analyses. It can be used with a graphical user interface, command line tools or through the R package Rsagacmd or RSAGA. Since the RSAGA package is no longer actively maintained and has not been tested on newer SAGA GIS versions, we recommend using Rsagacmd with SAGA GIS 7.9.0 and higher.


SAGA GIS is available in Puhti in r-env module with different versions.


SAGA GIS command line interface

r-env is an Apptainer container, which means the commands are slightly different compared normal installations, basically all commands need to have apptainer_wrapper exec before the usual command.

SAGA GIS command line tools can be used in an interactive session or batch jobs.

You can test that SAGA GIS loaded successfully and print the command line tools help information with

module load r-env
apptainer_wrapper exec saga_cmd -h

For more information on running R jobs on Puhti, please see the r-env documentation.

SAGA GIS Graphical User Interface

The easiest option for using SAGA GIS is to open it in Puhti web interface as Desktop app.

  1. Log in to Puhti web interface.
  2. Start SNAP: Apps -> Desktop, choose Desktop: 'single application' and App: 'SAGA GIS'
  3. The SNAP GUI is started automatically when the Desktop is launched.

Alternatively, especially if you want to use SAGA GIS together with some other GUI tool or want to user older version, SAGA GIS 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 SAGA GIS icon OR open Host Terminal (Desktop icon) and start SAGA GIS:
module load r-env
apptainer_wrapper exec saga_gui
