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 RSAGA.
SAGA GIS is available in Puhti with following versions:
SAGA GIS is included in the saga-gis module and can be loaded 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
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.
Usage with R
You can also utilize SAGA GIS functions through the RSAGA R library that is included in the r-env module. You can load it with
module load r-env
