I am doing supervised classification of vegetation types a L2A product using RF. I have previously collected field data (GPS points & vegetation attribute) which I have as a shapefile. I understand how to perform supervised classification by digitising training areas by specifying geometries, however I have no idea how to integrate the field data I have collected into the RF training and validation data. Can anyone who has experience in ground-truthing please give me a basic step by step of how this should be approached?
Many thanks to anyone who can help in advance
