+Over the past year, I have been creating and sharing fun spatial analysis problems using the hashtag #SpatialAnalysisChallenge on Twitter and LinkedIn. These challenges draw inspiration from real-world issues and serve as a means for the geospatial community to enhance their skills collaboratively. In this presentation, I will showcase some of the previous challenges and dive into the solutions that participants contributed using QGIS. Throughout the presentation, we will explore the diverse functionalities of QGIS - including Expressions, Geometry Generators, Processing Algorithms, PyQGIS, and more - showing how capable and versatile QGIS really is. Furthermore, I am excited to unveil a brand new #SpatialAnalysisChallenge tailored for the QGIS community during the talk!
