Image Detail
The Image Detail column indicates which pyramid layer is used last during the DTM mass point extraction. You can choose from the following options: As Is, 100%, 50%, or 25%. A value of 100% uses the original image as the last layer during the correlation process. A value of 50% uses the largest pyramid layer (that is, the first pyramid layer). A value of 25% uses the second largest pyramid layer (that is, the second pyramid layer). Figure 22 depicts the pyramid layers.
