QGIS turned twenty this year. The first lines of code were written in mid-February of 2002 and the first time the code compiled and ran, it could do one thing: Connect to a PostGIS database and draw a vector layer.

Quoting Gary Sherman - "The mythical man of QGIS that no one has ever met": This was the humble beginning of one of the most popular open-source GIS applications. GRASS GIS is of course the granddaddy of open source GIS, but the 20th birthday of QGIS is a testament to its longevity and commitment of all those who have made it what it is today.

In this talk I'll share a walkthrough of the most game-changing features and events that shaped QGIS and its community in the past 20 years making it one of the top ten most important C++ open-source projects [1] and an overall amazing project to represent :)

Happy Birthday QGIS!
