I have created a land use land cover map using the SCP plugin of QGIS. I want to perform accuracy assessment of this classified image by creating 100 sample points for each class and importing them into Google Earth. This option, however, is unavailable in SCP. There is only an option to provide a reference shapefile (created from my ROI training file) or a raster image for the assessment.
If this is not possible, is there an option for performing stratified random sampling for each class using the raster itself, without having to polygnize it?
