Lecture
This lecture covers the different methods and tools available in QGIS for integrating vector layers, including combining vector layers, using SQL queries for vector-vector integration, and performing operations like point-point and line-polygon joins. It also explores the concept of clipping vector shapefiles and applying boolean operators like union and intersection. The examples provided focus on Mahé Island and Praslin Island, demonstrating how to extract, combine, and analyze spatial data efficiently.
