Smoothing

Maps and plotting

Use the Smooth Horz/Slice Data function to smooth your horizon picks, isochrons, time slices, or gridded horizons without making changes to the original data. Smoothing is updated dynamically on your map so you can determine exactly what degree of smoothing you would like to apply. You need not calculate smoothed horizons in a separate math module. Simply post the data, smooth and plot your maps.

Save Smoothed data

Use the Save As New function to save the smoothing results to a new horizon name for display on your seismic sections, for use in gridding, or for ASCII export. See: Saving New Horizons

How to smooth data

  1. From the Mapmenu bar select Display | Smoother 1;1x1 . A window will open containing smoothing functions for 2D Lines and 3D Areas/Gridded Data. View image

  1. Move the slider bars to the right to increase the amount of smoothing. The smoothing function averages the values of the number of nodes specified by the slider. Smoothing is updated dynamically on the map and seismic.
  2. Select the Smooth <No Pick> check box to fill in missing data picks.
  3. Clear the Don't Smooth Across Faults check box to average the values on either side of the fault polygon.
  4. If you do not wish to interactively smooth your picks, clear the Dynamically Update Map check box. Smoothing will not be applied until you click the <OK> button.
  5. Click <OK> to exit window and apply changes to the display, or click <Cancel> to exit without applying changes.

Smoothing settings stay active until you re-set them. Any horizons, isochrons, etc. posted while a smoothing factor is set will be smoothed automatically.

Save smoothed picks for use in horizon math, gridding, or for export to other applications (see Saving New Horizons). Once you have saved your smoothed picks to a new horizon name, you can view the smoothed picks on your seismic data.

Smoothing contour lines

Smoothing can also be set for quick contour lines (see Marking Contours). This is a good way to determine how much smoothing you would like to apply before generating presentation contours (see Generating Contours).

Smoothing grids

Some gridding algorithms contain smoothing parameters that will affect the final grid (see Smoothing Grids).

Grid infilling

You can use the smoothing function to fill holes in a grid. Follow these steps:

  1. In the Smooth Horz dialog box, make sure the Smooth No Picks option is selected.
  2. Set the 3D Areas/ Gridded Data slider to 3x3.
  3. Click <OK>.
  4. In the Map menu bar, select Post | Post Horizon/Fault | Save as New...

WinPICS posts your grid with the holes filled in.
