While in the process of marking GCP’s it is possible to mark any GCP as a check point using the check box next to it as shown below.  Check points are marked clearly on the map.  Check points should be marked in at least 2 images as the case with the GCP’s.   GCP’s marked as Check Points will not participate in the model fitting calculations and will be used strictly for verifying the location of the point once the model is built.

Check Points Accuracy will appear in a standalone section in the accuracy report as shown below.
