Seismic Data Visualization Right click on seismic line Create Interpretation Window
The seismic interpretation window gives you a classic 2D view of the seismic data. Inline, crossline, composite lines and any type of random lines, can be displayed in the interpretation window. All interpretation tools are available in this window and the view can be zoomed, stretched and squeezed in either direction.
