Warning!

Puhti and Mahti are being decommissioned in stages, and their storage areas will become fully unavailable from 15 October 2026. Clean up unnecessary files and move any data you need to keep by 31 August 2026. See the Roihu data migration guide for instructions on transferring your data to Roihu.

Puhti computing services have been decommissioned and no new jobs are accepted or executed on its compute nodes. Puhti login nodes and storage services are planned to remain available until 15 October 2026.

GDAL

GDAL (Geospatial Data Abstraction Library) is a GIS translator library for accessing and transforming geospatial data. Most commonly it is used in file format or coordinate system changes.

Available

GDAL is available with following versions:

  • 3.12.4 - in the 3.44.9 QGIS in Roihu.
  • 3.12.2 - in the 3.14.5 python-geo in Roihu
  • 3.12.2 stand-alone: gdal in Roihu. Additionally is available proj/9.7.0.
  • 3.9.1 - in the 3.11.9 geoconda in Mahti
  • 3.8.3 - in the 3.31 QGIS in LUMI
  • 3.6.2 - in the 3.10.x geoconda in Mahti
  • Also in: r-env and OrfeoToolBox

Note

The stand-alone GDAL and R modules don't have Python bindings installed so e.g gdal_calc works only in the geoconda and qgis modules. Also, the supported file formats vary between the modules. It is possible to add more drivers to standalone and r-env GDAL installations, please ask. geoconda and qgis GDAL installations are based on conda gdal package and are impossible to change regarding drivers support. Use gdalinfo --formats to see supported raster formats and ogrinfo --formats for vector formats.

Usage

GDAL is included in the modules listed above, so it can be used when any of these modules is loaded.

The stand-alone gdal module is mainly meant for building software on top of GDAL, but can also be used for command-line usage. To load stand-alone gdal use:

# GDAL 3.12.2 (Roihu)
gcc/15.2.0  openmpi/5.0.10 gdal/3.12.2

You can test if GDAL loaded successfully with following

gdalinfo --version

Note that, starting with GDAL 3.11, parts of the GDAL utilities are available from a new single gdal program that accepts commands and subcommands.

Using files directly from object storage services or cloud, inc Allas

GDAL supports virtual network based file systems for reading and sometimes writing from several cloud storage systems, inc CSC Allas, Amazon S3, Google Cloud Storage, Microsoft Azure etc. Please check CSC's Using geospatial files directly from cloud, inc Allas tutorial for instructions and examples.

Virtual rasters

With large quantities of raster data (also in Allas), the most convenient method of accessing them might be GDAL virtual rasters.

Spatial datasets at CSC computing environment

Roihu has hundreds of Finnish spatial datasets available locally, additionally there is more in Allas and cPouta. More info under Spatial data in CSC computing environment
