SAGA GIS

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.

Available

SAGA GIS is available in Puhti with following versions:

  • 7.2.0

Usage

SAGA GIS is included in the saga-gis module and can be loaded with

module load gcc/9.1.0 saga-gis

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

saga_cmd -h

If you have connected with a ssh connection that has X11 forwarding enabled, you can launch a graphical user interface with

saga_gui

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

Note

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
