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.

In the input field it is possible to browse in multiple data sets. You may also specify folders as input. If this is case, all the data sets in the folder will be depth converted. When the input field has folders, the same folders will be created in the output folder. In order for the command to succeed, make sure that the output folder can contain the input data sets. Please note that a "Generic" folder cannot hold
seismic data set directly. However a "Generic" folder can hold a "Seismic Data" folder, which again can hold seismic data sets.
The depth conversion command has options to store the Average velocity used to do the depth conversion of each point in the result. You may also choose to store the "Instantaneous Velocity". The "Instantaneous Velocity" is computed by looking at the change of average velocity from the velocity model around a point. For seismic lines the the "Instantaneous Velocity" is the interval velocity of a single sample in the seismic. Storing and visualizing these velocities will make you able to quality control the velocity model used for the depth conversion.
