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 3.40.11-Bratislava) 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

Free data is provided for this course
(check Course System Requirements page to make sure your computer can run the programs and therefore the data set)
This course will provide you with a good understanding of how to conduct large scale vegetation health surveys and how to package the quantified analysis outputs into base line reports.
