Hi folks, I'm having some issues creating training points for the classification wizard. I have GPS points with confirmed presence and absence and I want to use them as training points for a classifier. But I need the training points to actually be pulling from drone imagery/continuous raster, which is what I will be classifying. I tried extracting the raster to the GPS points, but it doesn't allow me to input the extracted raster as the the training points or add fields to the attribute table. I'm trying to add class value and class name fields to the GPS points shapefile, but I'm not sure how the classification wizard will pull the spectral details from that since it is not a raster. Is there a way to marry the GPS points and imagery together to make training points containing pixel data for a classifier?
