I HAVE AN AERIAL IMAGE THAT I WOULD LIKE TO CLASSIFY BUT I NEED TO MASK OUT THE ISLANDS IN THE MIDDLE OF THE BAY. How can i create a mask first of these islands then classify the aerial image using a mask to block out the islands? I read a couple of other posts but I'm still having trouble following the steps. Thanks
