Chapter 6 Displaying Image Profiles
Overview
Normally, you view your imagery in DelphMap from the top down (“bird’s-eye”
view). DelphMap can also display your imagery in a side view. This is called a
Display Profile. The view takes the form of a single line showing the height and
breadth of whatever area you are profiling. While it is possible to get a display
profile from any DDS_VIF layer that has been designated as a cursor value layer,
a sidescan image only will show a profile of pixel values, since sidescan images
contain no topographical data.
To create and display a profile of part of your imagery
1. Set an image layer to display the Cursor value layer by right-
clicking on the layer name. See ‘Establishing a Cursor Value
Layer’ for the technique of setting a cursor value layer.
2. Click the Display a profile of the image icon. (There is no menu
equivalent.) The icon is shown here on the right:
3. Left-click in your imagery and move your cursor across an area for
which you wish to create a profile.
As you move the cursor in the described way, the system drags a
line or lines in the chosen direction.
4. Left-click again when your line covers the full length of the area you
are profiling.
The system displays the Display Profile window with your profiled
area in it.
5. If you intend to profile an area by a series of lines, left-click at the
terminus of a line and start a new (connected) line in a new direction.
The displayed profile continues to be generated in the Display Profile
window according to any additional lines you may have drawn.
Figure 47, Figure 48, and Figure 49 show examples of displayed
profiles.
