Syllabus

Introducing QGIS

This module introduces the fundamentals of QGIS (Quantum GIS), a popular open-source Geographic Information System software. Learners will be guided through the installation process of QGIS 3.0, exploring its features and graphical user interface (GUI) components such as toolbars, panels, and plugins.

Working with Shapefiles

This module focuses on practical skills for working with geospatial data in QGIS. Learners will learn to download and work with shapefiles, including styling vector and raster data. The module also covers handling attribute data using tools like the Field Calculator and selecting features within QGIS.

Exploring Maps

This module covers cartographic techniques and tools available in QGIS for map representation and styling. Learners will explore coordinate systems, projections, and create various thematic maps such as choropleth, graduated symbol, heat maps, and dot distribution maps. Additionally, the module covers map layout techniques and essential data integration and analysis tools within QGIS.

Georeference & Digitization of Toposheets

This module focuses on georeferencing and digitization techniques using QGIS. Learners will understand the process of georeferencing toposheets, including downloading and setting transformation parameters. They will also explore digitization techniques for creating point, polyline, and polygon datasets from toposheets.

Georeference & Digitization of Open Street Maps and Google Earth Images

This module focuses on advanced techniques for digitizing and georeferencing spatial data from online sources using QGIS.
