I am trying to transfer (copy> paste) manually created mask geometry from C2X image to C2RCC image, but the mask somehow mismatch obviously about 10-15 % (even more) aside? Any ideas?
It is better if you export your mask as a vector and import it again in the second product. Right click on the image and use the “Export Mask Pixels” option and then select you geometry on the list. Write to file and give it an appropriate name. You could also save as a shape file clicking the right button with the cursor on the vector data (in the Product Explorer list).
