Tutorials

The course features a series of practical tutorials in which participants carry out exercises, further developing skills learnt during the course.

Tutorial 1: Spatial queries and geoprocessing in Spatialite

A Spatialite database will be developed, populated and queried using tools and plugins available in QGIS. Participants will learn how to fetch data using SQL queries and how to use Spatialite functions.

Trainees will find parts of a site suitable for development by geoprocessing several environmental constraints.

Tutorial 2: Generating line-of-sight maps for wind farms

In this tutorial, participants will assess visual impacts of a wind farm by using the line-of-sight module from the Processing algorithm and raster calculator.

Tutorial 3: Creating heat maps

Based on a hypothetical dataset, a heat map of Anti-Social Behaviour Orders (ASBOs) in Staffordshire will be generated.

Tutorial 4: Calculating optimal tilt for solar panels

In this tutorial participants will work with the graphical modeler and batch processing to generate optimal tilt for solar panel using a digital terrain model and Linke Turbidity Factor maps.

Tutorial 5: Determining the watershed and drainage system for a catchment

In this tutorial, participants will determine a hydrological catchment and natural drain network on the Isle of Wight using modules in GRASS GIS through the Processing toolbox
