How to display data from two or more horizons simultaneously

To view multiple horizons, or multiple attributes of one horizon, there are a few options, depending on what you would like to achieve:

Use multiple map view

Open a second Map view to display each horizon (see Volumes and horizons in Map View).

There are two approaches:

  • From the Control Panel, View menu, choose New Map View, OR
  • Right-click on an existing map view and choose “Duplicate this window”

Merge using horizon maths

To combine two (or more) pieces of a horizon to a single surface:

  • Use Operations > Horizon Maths
  • Add each of the horizons to merge
  • Use the Formula: merge (a, b)

For more on horizon maths see Common horizon tasks in horizon maths.

Using 3D view

  • Open the 3D view
  • In the Control Panel > Horizon tab, toggle the display of each horizon using the 'traffic light' icon
  • Enable the option in the Control Panel to display the horizon as a 3D surface, not the intersection (see Horizon Overview).

In the 3D view, different attributes can be displayed for horizon. To display multiple attributes for the same horizon, create a duplicate and display a different attribute for each.

  1. Duplicate your horizon (see Copying a Horizon).
  2. In the Control Panel, display the original and hide the copy.
  3. Right-click on the original horizon in the 3D view and choose "Settings for Horizon".
    • Select the property to display.
    • Click the class and set the opacity.
  4. In the Control Panel, hide the original and show the copy.
  5. Right-click on the duplicate horizon in the 3D view and choose "Settings for Horizon".
    • Select the property to display.
  6. In the Control Panel, show the original horizon again.
  7. Both horizon attributes are now displayed together.
