Seismic data is used to visualize the Earth's sub surface. This is achieved by measuring travel times of reflections from pressure waves propagating through the ground. Seismic data and interpretations of seismic data will therefore often have z values in travel time, not depth. In order to get a depth value for a travel time value, we need to do a depth conversion. A depth conversion combines the velocity of the pressure wave with the travel time to get a depth value.

During depth conversion, the interval velocities are used to calculate an average velocity.

Stacking velocities)
The RMS velocitiy model uses RMS velocity data sets as input. It is possible to select a single data set in the project as input, but you may also select a folder containing multiple RMS velocity data sets as input. In some cases Stacking velocities may be used as RMS velocities.
