[OpendTect_Users] OpendTect - creating a seafloor map by first breaks

[Hesham Refayee]

Hi Steven,

I am happy to know that you like our product.

You may try this work flow to create a horizon from steering cube using one
seed only.
*Processing>HorizonCube>Horizons from SteeringCube -Create->> GO.*

However, you will need to create steering cube which contains the dip and
azimuth of the seismic events before you do the above workflow.

Here is a pdf file explains what is a steering cube and how to create it.
