Seismic Scales Tab

Use the Seismic Scales tab to set the scale for your wiggles and traces in the Seismic view. View image

This tab has the following options:

Vertical scale

Enter a value for the number of inches per second to use to display the traces.

Horizontal scale

WinPICS can draw traces at trace scale or at map scale. Trace scale draws your seismic with a fixed distance (in TPI) between traces, while map scale is variable and presents a spatially accurate representation of the traces.

Trace Scale

To draw your traces at trace scale, follow these steps:

Select the Use Trace Scale Mode option.
In the Traces Per Inch field, select the number of traces per inch, as shown in the Seismic display, you want WinPICS to draw.

Map Scale

To draw your traces at a map scale, follow these steps:

Select the Use Map Scale Mode option.
In the Scale 1 field, type the scale, as shown on your map, you want WinPICS to draw traces at. The default setting is the scale of your current map. For example, a scale of 1:20000 means your traces will be drawn so they match the length of your line at a map scale of 1:20000 meters.

The Map Scale feature is useful for comparing two seismic vintages with different trace spacing.

Trace Decimation

Trace decimation controls how many seismic traces WinPICS displays. You have the following options:

Auto - Select to have WinPICS automatically decimate traces displayed on the seismic window based on the selected scale.
Enter a number to customize how many seismic traces WinPICS displays. A setting of 1 means that WinPICS displays every trace; 2 means that every other trace is displayed, etc.
