This package was approved as a trusted package on 7/16/2018.

QGIS is a user friendly Open Source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo). It runs on Linux, Unix, Mac OSX, Windows and Android and supports numerous vector, raster, and database formats and functionalities.

General Features

  • View data -- Spatially-enabled tables and views, vector formats, raster and imagery formats, GRASS raster and vector data and online spatial data.
  • Explore data and compose maps -- Interactively explore spatial data with a friendly GUI with many helpful tools.
  • Create, edit, manage and export data -- Vector and raster layers in several formats.
  • Analyze data -- vector analysis, sampling, geoprocessing, geometry and database management tools including the complete GRASS functionality of more than 400 modules.
  • Publish maps on the Internet -- QGIS can be used as a WMS, WMTS, WMS-C or WFS and WFS-T client, and as a WMS, WCS or WFS server.
  • Extensible functionality through plugins
  • Python console

This package will install the identified, "Long Term Release" version of QGIS intended for stability. If you want to install a version more rich with features but potentially less stable, try the package for the latest release of QGIS. These packages can now co-exist!

Keeping old releases

Upon installation/upgrade, this package will attempt to remove the newest version of QGIS less than or equal to this package version. (It will no longer remove non-"LTR" versions.) If you would like to skip the uninstallation of any older versions, use the a "Keep" package parameter as follows:

choco install qgis-ltr -params '"/Keep"'

This parameter will be ignored if the newest version has the same major.minor value as this package because the QGIS installer won't allow two different builds of the same major.minor release. (I.E. Version 2.18.14 has the same "2.18" as version 2.18.20.) This parameter would allow you to keep a v2.14.x install of QGIS when installing a v2.18.x package.

Uninstallation should remove only the installed, Chocolatey package version.

To install QGIS LTR (Long Term Release), run the following command from the command line or from PowerShell:

C:\> choco install qgis-ltr

To upgrade QGIS LTR (Long Term Release), run the following command from the command line or from PowerShell:

C:\> choco upgrade qgis-ltr

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.


This package has no dependencies.
