GIS 7.4.0


After a bit more than a year of development the new update release GRASS GIS 7.4.0 is available

GRASS GIS 7.4.0 provides more than 480 stability fixes and improvements compared to the previous stable version 7.2. An overview of the new features in the 7.4 release series is available at New Features in GRASS GIS 7.4.


Efforts have concentrated on making the user experience even better, providing many small, but useful additional functionalities to modules and further improving the graphical user interface. Users can now directly download pre-packaged demo data locations in the GUI startup window.

A series of new features and stability fixes, manual improvements, and a few language translations have been added. The GRASS GIS 7.4.0 release provides more than 710 fixes and improvements with respect to the stable release 7.2.0.

Several modules were migrated from addons to the core GRASS GIS package and the suite of tools for ortho-rectification was re-implemented in the new GRASS 7 GUI style. In order to support the treatment of massive datasets, new compression algorithms were introduced and NULL (no-data) raster files are now also compressed by default. For a detailed overview, see the list of new features. As a stable release series, 7.4.x enjoys long-term support.

The Geographic Resources Analysis Support System (, commonly referred to as GRASS GIS, is an Open Source Geographic Information System providing powerful raster, vector and geospatial processing capabilities in a single integrated software suite. GRASS GIS includes tools for spatial modeling, visualization of raster and vector data, management and analysis of geospatial data, and the processing of satellite and aerial imagery. It also provides the capability to produce sophisticated presentation graphics and hardcopy maps.

GRASS GIS has been translated into about twenty languages and supports a huge array of data formats. It can be used either as a stand-alone application or as backend for other software packages such as QGIS and R geostatistics. It is distributed freely under the terms of the GNU General Public License (GPL). GRASS GIS is a founding member of the Open Source Geospatial Foundation (OSGeo).
