The 2D Scatter Point module is used to interpolate from groups of 2D scattered data to other objects (meshes, grids, TINs). Several interpolation schemes are supported, including kriging.

Interpolation is useful for setting up input data for analysis codes and for site characterization. The two figures below show examples of using interpolation.

Once a scatter point is created or imported, it can be saved as part of the current project using the Save command in the File menu. When scatter point data are saved, the scatter point locations (xy coordinates) are saved to a Scatter Point file and the datasets are saved to a Dataset file.
