Interpreting with auto-tracking: To select Snap mode look at the seismic display and identify the reflector representing the seabed. Compare the color of the seabed reflector with the seismic color table. The color on the left side of the color table represents minima; the color on the right represents maxima. The seismic color table used is one of three: - current active seismic color table – look in the lower right corner of Geocap.
- the color table specified in Seismic display, if any.
- the color table dragged and dropped on top of the seismic line, if any.
- Select Snap mode accordingly.
- Select Track mode to be Auto.
- Set Delta Z. Delta Z is the maximum allowable vertical distance between two auto-tracked points. Z is usually time in ms. A good rule of thumb is that Delta Z should be the double of the sample interval in the seismic. In our case that is 8.
- Pick the horizon to autotrack by clicking the p key on the keyboard
- The horizon is automatically interpreted
