Quick Image Classification Accuracy Assessment in ArcGIS Pro

Would you like to assess the accuracy of your image classification without manually labeling the control points with the values from the ground truth class? Learn how to use an existing classified raster as ground truth and generate control points and the misclassification (or confusion) matrix with three simple geoprocessing tools.

Hi Miriam, thank you for sharing this amazing video in RUclips. I just want to ask regarding the ground truth points. Are these points taken from a ground survey?

Hi, I am trying to assess the accuracy of a classified raster in ArcGIS. To do this, arc has a function to generate random points for accuracy assessment. However, the points that are being generated are spread across my raster even beyond the extent of my clipped ROI i.e. in the NoData extent beyond my watershed. What could be the possible reasons for this and how do I avoid it?
Thank you in advance!
