Topic:
How to create a depth map using one velocity value.

Description:
 

Solution:
For creating depth maps in the xyz domain:

1.) Select > Horizon, select horizon and time attribute.

2.) XYZ operations > Bias and Scale.
   - Type in velocity in Scale Factor.
	Input negative value if want depth values to be positive.
	Input 1/2 the velocity.
   - Toggle scale units to vel (ft/s) or vel (m/s)
   - Type in resultant surface name, Exit.

3.) Select the contour icon to display the depth grid and/or select the
    basemap icon (above the contour icon) to display the depth values.


For creating depth maps in the grid domain:

1.) Select > Horizon, select horizon and time attribute.

2.) Grid horizon. Edit > Grid Contour.
    - Change parameters accordingly and Exit.

3.) Up-arrow > Grid operations > Bias and Scale.
   - Type in velocity in Scale Factor.
	Input negative value if want depth values to be positive.
	Input 1/2 the velocity.
   - Toggle scale units to vel (ft/s) or vel (m/s)
   - Type in resultant surface name, Exit.

4.) Select the contour icon to display the depth grid.
