This document provides an overview of mapping and GIS functions in QGIS including: 1. Opening existing vector data layers, manipulating their properties, and saving projects. 2. Working with layer attribute tables to calculate geometries and fields. 3. Creating new shapefiles from GPS coordinates, selections, and by converting existing features. 4. Using analysis tools like buffer and union to examine overlaps between layers showing land use permissions, plantations, and satellite imagery.
