QGIS can be found on GitHub under github.com/qgis/QGIS. If you want to contribute patches, you can plug in the project, make your changes, commit to your repository, and then create a pull request. The development team can then review your contribution and engage it upstream if necessary. If the modified program normally reads commands interactively when it is run, you must have it printed or display, when executed in the most ordinary manner for such interactive use, an advertisement containing a corresponding copyright notice and a notice that there is no warranty (or that you give a warranty) and that users may distribute the program under these terms. and tell the user how to view a copy of this license. (Exception: If the program itself is interactive, but usually does not print such an ad, your program-based work is not required to print an ad.) QGIS is released under the GNU General Public License (source: www.qgis.org/en/site/about/index.html), so yes, it can be used for commercial purposes (see also: en.wikipedia.org/wiki/GNU_General_Public_License). Customization: Freedom to customize the application to your needs, from custom data entry forms to custom user interfaces and workflows. We ask you to take into account the fact that several thousand hours of work and significant financial expenses of individuals and companies have been devoted to the creation of QGIS. This work is carried out on the basis that the benefits in kind increase the quality and capabilities of the platform for all.

When you create a plugin, you only have to make a minimum of effort to meet your specific needs, as we have done the rest of the work necessary to provide a complete platform for you and our community of users. This is an important open source value proposition: “A rising tide makes all boats float.” These requirements apply to all modified work. If identifiable portions of such work are not derivative of the Program and can reasonably be considered independent and distinct works per se, this License and its terms do not apply to those sections if you distribute them as separate works. But if you distribute the same sections as part of a whole that is a work based on the Program, the distribution of the set must be done under the terms of this license, whose rights to the other licensees extend to the whole and therefore to each individual part, regardless of who wrote it. QGIS is open source software and provides an excellent platform for third parties to distribute additional functionality to users through our plugin system. QGIS is licensed under GPL version 2 or higher. This license comes with each copy of the QGIS and in the source code and is available on our website here: QGIS acts as a geographic information system (GIS) software that allows users to analyze and modify spatial information and create and export graphics maps. [3] QGIS supports raster and vector layers; Vector data is stored as point, linear, or polygonal features. Multiple raster image formats are supported and the software can georeference images.

You must ensure that any work you distribute or publish that contains, in whole or in part, or is derived from, the Program or any part thereof, is licensed in its entirety and free of charge to all third parties under the terms of this License. Each time you distribute the Program (or any work based on the Program), the Recipient automatically receives a license from the original Licensor to copy, distribute, or modify the Program in accordance with these Terms and Conditions. You may not impose any other restrictions on recipients in exercising the rights granted herein. You are not responsible for third party compliance with this License. QGIS is a volunteer-run project. We welcome contributions in the form of code messages, bug fixes, bug reports, contributed documentation, advocacy, and support for other users of our mailing lists and gis.stackexchange.com. If you want to actively support the project, you can find more information in the development menu and in the QGIS wiki. QGIS is released under the GNU Public License (GPL) version 2 or later. The development of QGIS under this license means that you can (if you wish) view and modify the source code and ensures that you, our happy user, always have access to a free and freely modified GIS program. If, as a result of a court order or allegation of patent infringement or for any other reason (not limited to patent matters), conditions are imposed on you (whether by court order, agreement or otherwise) that conflict with the terms of this license, they do not release you from the terms of this license. Therefore, if you are unable to simultaneously perform your obligations under this License and other relevant obligations, you may not distribute the Program at all.

For example, if a patent license does not allow the royalty-free redistribution of the program by all those who receive copies directly or indirectly through you, then the only way to run it at once and that license would be to stop distributing the program altogether. Under the terms of this license, it is mandatory that all plugins distributed through plugins.qgis.org (or through other repositories that can be self-hosted) comply with GPL version 2 or later. .
