[OSGeo-Discuss] QGIS plug-in-based software

[Oskaras Alsauskas]

Hi there!

My name is Oskaras Alšauskas and I work for Swedish software development and energy consultancy company.

We have been investigating a possibility of developing a software for energy networks modelling and simulation, that would be used by energy engineers, consultants, and utilities all over the world.

Our company came to a conclusion that the most efficient way to deliver such technology would be to develop the software as a QGIS plug-in, since QGIS is a GIS platform with marvellous features that are necessary for networks modelling and visualization to boot. Therefore, I would like to ask you few questions:

 1) Are there any kind of restrictions, licenses, or fees to take care of in order for us to sell licenses and distribute our QGIS plug-in-based solution commercially?

2) Do you know what is the usual license selling approach when it comes to QGIS plug-in-based software, since any QGIS plug-in must be open source?

I have come across companies selling their QGIS plug-in(s)-based software and initially thought that there should not be any issues for us to do the same, but after diving into the GNU GPL it looks like there are plenty of details, we have to figure out before making the decision.

Any kind of information regarding the QGIS commercial use topic will be highly appreciated.

Looking forward hearing from the community.


Best regards,

Oskaras Alšauskas
