The intermediate course will look at using GIS to analyse vegetation health and quantifying vegetation data using RGB data. This will form a base line data set which can be used to monitor vegetation over time. You will need to download and install QGIS (this course uses QGIS version 3.28.14-Firenze) and Cloud Compare ( this course uses 2.12.4 Kyiv, Stereo) from the Software/ Hardware Requirements page to complete this course. It is recommended that you complete the Foundation course before attempting the Intermediate course. Here we will look at how to use photogrammetry outputs to
