Somehow you’ve ended up here and hopefully you have questions on QGIS. You may have questions on GIS (Geographic Information Systems) but I’m not going to cover much of that information. I’m assuming you have a basic understanding of GIS or can dig around the internet to find more information on that subject.

QGIS was started by Gary Sherman back in 2002. Version 1 was released in 2009 so you can see it hasn’t been out long with relation to other Open Source GIS Software. QGIS is now at version 3.x.

With QGIS being open Source – you may be wondering what that ultimately means to you? Well since it is Free and Open Source you have freedom to:

  • The freedom to run the program as you wish, for any purpose.
  • The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
  • The freedom to redistribute copies so you can help your neighbor.
  • The freedom to distribute copies of your modified versions to others. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

Is it safe? A lot of people worry about the security and the safety of Open Source Software.

It’s great software! It’s a great community! So let’s keep moving along and install it!
