WMS:2D Scatter Point Module
The Scatter Point module is used to interpolate from groups of scattered data points to grids or TINs. The Scatter Point module can be used to interpolate from a set of scattered xy points representing something like rain gages to a finite difference grid or to basin centroids for establishing rainfall curves for HEC-1. A variety of interpolation schemes are supported.
Scattered data can be created using the create point tool. The most common use of scattered data are for creating water surface elevations to compute a floodplain delineation. Generally in such cases you will want to take advantage of a centerline and cross sections to develop a larger dataset for flood plain delineation.
Scattered Data Tools
The following tools are active in the dynamic portion of the Tool Palette whenever the 2D Scatter Point module is active.

The Select Scatter Point tool is used to select individual scatter points for displaying the coordinates and current function value of individual scatter points in the Edit Window.

The Create Scatter Data Point tool is used to create new scatter points. The primary purpose of creating scatter points is to enter water surface elevations that can be used in a flood plain delineation. It can only be used in plan view.
