However, it is possible to define another value range for CL by overwriting the value range defined in CL1. In CL2, a valid value range of 15 - 50 was specified for C1. When you assign CL2 to CL1, the value range for C1 was restricted to 10 - 20. The intersection from the value range in class CL2 and the value range specified during classification results in the value range 15 - 20. You can only valuate object O1 with value from this value range.
