Grid Data Inside or Outside

Follow these steps:

  1. Create a Map Drawing Polygon or open an existing polygon file.
  2. To grid data inside or outside of a polygon boundary, right-click to open the Map Drawing menu.
  3. Select Grid | Data Inside or Outside. The Choose Horizon For Gridding dialog box will open.
  4. Select data and click <Execute> to proceed to Create Horizon Grids.

If you Grid Inside data, only the data which falls within the polygon will be used in gridding. Grid Outside will grid only the data that falls outside of the polygon area. See examples below.

Grid Data Inside

Grid Data Outside

When you use a polygon to limit data for gridding, the data points specified by the polygon will be displayed in the Kernel Gridding window. You may arrange your grid geometry as you like.

Gridding will be done using only the specified data. After gridding, all grid nodes in the area excluded by the polygon are dropped.
