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

Tutorial 1: Importing and Styling OpenStreetMap datasets in QGIS

Data from OpenStreetMap will be loaded and styled in a Spatialite database.

Tutorial 2-5: Installing, configuring and importing data to PostGIS

Participants will install and configure PostGIS. After connecting to the PostGIS database in QGIS, participants then load Ordnance Survey's Integrated Transport Network ™ (ITN) Layer and Topography Layer data from the OS Mastermap® to PostGIS using OS OS Translator II plugin in QGIS and style them accordingly.

Mastermap data loaded in a PostGIS database

Mastermap data loaded in PostGIS through OS Translator II and visualised in QGIS.

Tutorial 6: Creating a Digital Terrain Model for Great Britain

Participants will generate a DTM for Greate Britian using 2858 raster tiles from Ordnance Survey's OS Terrain 50 dataset

DTM of Great Britain

Digital terrain model of Great Britain generated using GDAL tools

Tutorial 7: Working with PostGIS rasters

Rasters from the previous tutorial, will be imported in a PostGIS database. Participants will explore some of the PostGIS raster functions in this tutorial.
