QGIS can be used to: 1. Create vector data with a specified radius, add online basemaps, and display data from OpenStreetMap or Google Maps. 2. Visualize route distances between points on a spider graph or line hub. 3. Join or update attribute fields for vector data or tables by selecting the appropriate column. 4. Generate Voronoi polygons and buffer zones for vector data, and clip any areas outside an overlay layer. 5. Export vector layers to KML/KMZ formats for use in Google Earth. 6. Aggregate multipart features in a layer into single part geometries.
