OSGeo4W

OSGeo4W is an installer for a broad set of open source geospatial software packages including GRASS as well as many other packages (QGIS, GDAL/OGR, and more).

OSGeo4W v2 is the standard repository and does not include a 32-bit version. The legacy v1 installer below is only needed for 32-bit systems. Upgrading an existing v1 installation by pointing it at the v2 repository is not supported — do a fresh install or use a different install directory.

Legacy download (OSGeo4W v1)

The following install modes are offered (see also the dedicated wiki page for further details):

Express Desktop Install mode:

Run the downloaded installer as administrator and select the grass (stable) or grass-daily (development) packages to install. All needed dependencies (e.g. GDAL, common python packages) will be automatically downloaded.

Advanced Install mode:

All packages can be individually selected and additional useful packages (e.g. python-pandas, msys) are available, too.

Command line mode:

Installation can also be done through command line, as shown below:

osgeo4w-setup.exe -q -k -P grass -s https://download.osgeo.org/osgeo4w/v2/x86_64/

QGIS users:

In order to have GRASS support (also in QGIS-Processing) you need to install the “qgis*-grass-plugin” packages.
