Intro to GIS and QGIS

GIS is how you work with geographic data: mapping where things are, analysing spatial patterns, and visualising what you find. You’ll use it to answer questions like which streets get foot traffic, which neighbourhoods lack green space, or where densities are highest.

We’re using QGIS because it’s open-source and widely used. Since it’s free, you can keep using it after the course ends.

What’s in This Lesson

  1. GIS Concepts: Vector vs raster, file formats, coordinate systems. The vocabulary you need before opening the software.
  2. Intro to QGIS: The interface, plugins, and project files. Getting oriented before you start working with data.
  3. GIS Data: Loading, exporting, and creating layers. The operations you’ll repeat constantly.
  4. GIS Maps: Styling and layout. Making maps that communicate what you want them to.

Datasets
