This course builds on existing basic GIS and database knowledge and introduces tools and plugins in QGIS to help with managing large raster and vector datasets.
After a brief introduction to the basics of geodatabases and DB Manager in QGIS, participants will set up a database and import vector data from OpenStreetMap and Ordnance Survey.
A digital terrain model (DTM) for Great Britain will be generated using GDAL tools and Ordnance Survey's OS Terrain 50 dataset.
GIS users often deal with large volumes of raster or vector data. This training course will help participants learn about the tools and plugins available in QGIS for managing their datasets.
Participants will acquire the following key skills:

The course features a series of practical tutorials in which participants carry out exercises, further developing skills learnt during the course.
Data from OpenStreetMap will be loaded and styled in a SpatiaLite database.
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 (OS MasterMap® ) into PostGIS using the OS Translator II plugin in QGIS and style them accordingly.
Participants will generate a DTM for Great Britain using 2858 raster tiles from Ordnance Survey's OS Terrain 50 dataset
Raster data from the previous tutorial will be imported into a PostGIS database. Participants will explore some of the PostGIS raster functions in this tutorial.
