    Study Notes

    QGIS Training Overview

    • QGIS is a free and open-source Geographic Information System (GIS) program.
    • It's free in terms of cost and freedom to modify.
    • QGIS is continuously being developed and improved by users and developers.
    • Comprehensive help and documentation are available for support.
    • It runs on multiple operating systems (macOS, Windows, and Linux).

    QGIS Training - Background

    • QGIS was launched in 2008 with a free, open-content introduction to GIS.
    • It was sponsored by the South African government.

    QGIS Training - Interface Overview

    • Layers List/Browser Panel: Displays all available layers and their properties (name, geometry type, coordinate system).
    • Toolbars: Holds frequently used tools like file operations and project management.
    • Map Canvas: The main area where the map is displayed. Users can interact with layers by zooming, panning, and feature selection.
    • Status Bar: Displays current map scale, rotation, and coordinates.
    • Side Toolbar: Displays options for creating new layers and loading existing layers.
    • Locator Bar: Allows searching for geographical locations and coordinates.

    QGIS Training - Tools and Bottom Status Bar

    • The Status bar allows users to input map scale values.
    • The Locator bar provides tools for various map functions such as filtering, digitising and more.

    QGIS Training - Layer Panel

    • The Layer Panel (map legend) displays layers in the project and lets you manage their visibility.
    • Layers can be reordered by dragging in the legend to change Z-ordering.
    • A toolbar at the top of the panel allows adding new groups, managing map themes, filtering layers, and showing/hiding private layers.
    • Features can be filtered using expressions.

    QGIS Training - Bottom Status Bar

    • The bottom status bar shows the current map coordinate, scale, magnifier and rotation.
    • Users can enter map scales and press enter to update the view.

    QGIS Training - Layer Panel

    • The layer panel helps manage the visibility of layers within a project.
    • Layers can be reordered in the map legend.
    • You can add new groups, control visibility, filter layers, and display/interact with 'private' layers.
    • The panel lets you filter layers by contents.
