This is an intermediate course focusing on aggregating vector and raster data for geospatial visualisation and analysis. The course will introduce the reasons for aggregating geographies, how to perform aggregation in the QGIS environment and basic methods to visualise these patterns and to perform some basic analysis studying correlations between aggregated variables. The session will be operated in the format of Silent Disco where students will be completing the tutorial at your own pace. If you are stuck with certain operations, you could access help via the teams chat set up for today's session. THe session should last appropriately 2 hours covering the following headings,
- To aggregate vector and raster information to polygons to aid in visualising patterns of geospatial information.
- To construct polygon bins and apply spatial join techniques to aggregate vector-based point data to create a multi-variable dataset.
- Extract and align raster data with polygon bins using zonal operations to create a multi-variable dataset.
- Export aggregated dataset for further statistical analysis or quick exploration with consoles in QGIS.
- A zipped file of all the geospatial data and scripts required for the session.
- The link to a website to the tutorial. Please click onto the link to view the instructions and steps to complete for the Silent Disco.
- A folder that says assets/images. Please ignore contents inside as they are only to provide screenshots referenced into the main tutorial.
You will need QGIS installed on your machine (the current Long-Term Release is version 3.10.10 ‘A Coruna’). You can download and install it from https://qgis.org/.
