SAGA GIS

Saga GIS (System for Automated Geoscientific Analyses) is a GIS application for spatial data editing and GIS analyses.

Available

SAGA GIS is available:

Usage

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 Since the RSAGA package is no longer actively maintained and has not been tested on newer SAGA GIS versions, we recommend using Rsagacmd with SAGA GIS 7.9.0 and higher. For more information on running R jobs on Puhti or using RStudio, please see the r-env documentation.

For using SagaGIS, any of the modules listed about must be activated first, check the linked pages for details.

SAGA GIS command line interface

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

SAGA GIS command line interface with r-env module

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

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

apptainer_wrapper exec saga_cmd -h

SAGA GIS command line interface with qgis module

With qgis module SagaGIS commands can be used normally, for example:

saga_cmd -h

SAGA GIS Graphical User Interface

SAGA GIS Graphical User Interface in Puhti

To use SAGA GIS, open it in Puhti web interface:

  1. Log in to Puhti web interface.
  2. Open Desktop app.
  3. After launching the Desktop, double-click SAGA GIS icon OR open Terminal (Desktop icon) and start SAGA GIS:
module load r-env
apptainer_wrapper exec saga_gui

SAGA GIS Graphical User Interface in LUMI

Until LUMI web interface is available, SagaGIS needs to be used with SSH X11 forwarding.

module use /appl/local/csc/modulefiles
module load qgis
saga_gui
