Intro 

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 understand vegetation dryness and separate soil and dead plant values out of RGB drone data and quantify healthy/moderately healthy vegetation and dry/soil information in cubic metres and so much more. The processes and tools used in the Intermediate Course are transferable to other industries such as agriculture, mining and industrial applications as well!
