Dear
Many thanks for the video was helpful.
So, how to save this classified image properly, for later use in the process of change detection analysis.
I applied the same procedure for image classification, but I can not save it in the TIF or PIX image format to perform coverage change analysis. Could you please explain to me how I can save the sorted image, and how I can initiate the change analysis.

How did you create the Seg_25_J layer just previous to the Rule-Based Classification? I can't for the life of me figure out how to create a layer with both Parent_C and Child_C as available attributes.

Hi, thank you for your demonstration. I have questions here.
1) Did you joined attribute tables of Seg 25: Child_C and Seg_150: Parent_C to become seg_25_J layer before the step of Rule-based Classification?
2) I assumed you did joined Seg 25: Child_C and Seg_150: Parent_C before Rule-based Classification. I saw you performed reclassify or I rather think it is feature extraction to class polygons from shadow to become open in Re-Class_1 using rule condition based on Seg 25: Child_C and Seg_150: Parent_C., how did you replaced those polygons classified as shadow in Seg 25: Child_C with the same polygons classified as open in Re-Class_1 (since each of these polygons at the same time is shadow and open in the both layers I mentioned) to produce seg_25_joined as the final classification output?
