I am using QGIS and the SCP plug-in to classify a sentinel 2 image.
As for the reference shapefile my point layer, is a vector point layer containing the names of crops, which were used in creating ROIs.
My question is: Do I need to alter this crop point file file further in order to generate a valid accuracy assessment? I am aware it needs to be converted into either a shapefile or raster, but Do I need to attach the pixel values from the ground truth image to the crops, in order to use this as a reference layer?
I have computed accuracy assessments already but they are between 0.02 and 4%.
