Take a minute to see what information is included. This is all the information available for that area of land – the Admin 1 shape that you clicked on. This will look something like the image below: In the “Identify Results” window that opens on the right, you should see a summary of the attributes associated with this feature. Click on the Identify Features tool in the top bar, then click on any of the Admin 1 areas.We will now use the identify features tool to discover what information is associated with each of the Admin 1 areas. This option zooms to the full extent of the chosen dataset, and it is useful to visualise a dataset in its entirety. Right click on your Admin 1 layer and select Zoom to Layer.Turn off the display of all layers (unclick them in the “Layers” list) then turn on the display of your polygon layer – Admin 1.(This should be stored within your Maps folder) Open the project that you saved at the end of Module 1.In Module 1, we had opened three vector files: a point file for settlements, a line file with roads and a polygon file with administrative boundaries. If you have not completed the practical exercise for Module 1, please do so before proceeding. This contains most of the data you need to start this session. Let’s start by opening the project that you saved at the end of Module 1. In this video, we will go over the similarities and differences between vector and raster datasets, and in the accompanying tutorial, you will learn how to work with both in QGIS. Maps are often made up of layers of both types of data. There are two main types of spatial data: vector and raster data.
