Thank you so much @ThomasHamill . I have another problem with my maps. Kindly see the attached files.
Map 2 has an unknown source and therefore, I try to use the 'define projection'. I input the projection of Map 1 for them to overlap. However, even with the same projection, it did not work. Please help me how to adjust the projection of Map 2 correctly to overlap it with Map 1. I sincerely can't find a solution to this. I am hoping for your immediate and positive response. Thank you.
