Smoothing
Grids - Overview
There are three main factors that affect the smoothing of your grid:
- Smoothing
after gridding - Once you have created your grid and posted it to
your map window, you can smooth its appearance by selecting Smooth
Horz/Slice Data. This is a simple averaging of data values that
does not change the original grid values.
- Gridding
method - Gridding methods are algorithms that are applied to your
horizon data to calculate and assign values to a grid. Some algorithms
are specifically designed to smooth grid node values or have options to
apply additional smoothing functions to grid node value calculations.
See Weighted
Average Interpolator for a discussion of smoothing algorithms versus
exact algorithms.
- Gridding
geometry - Grid geometry controls the sampling of your input data
values. Contours are created by connecting grid nodes and their smoothness
depends on the number of grid nodes available to define the shape. Coarse
grids produce fewer grid nodes and therefore more blocky or angular contours.
