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 Scatter Point tool. The most common use of scattered data are for creating water surface elevations to compute a floodplain delineation. Generally, in such cases, take advantage of a centerline and cross sections to develop a larger dataset for floodplain delineation.

2D Scatter Point Tools

The toolbar for the 2D Scatter Point module.

The toolbar for the WMS 2D Scatter Point module has a variety of tools useful for editing and creating objects within that module. The tools are described below.

Select Scatter Point

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.

Create Scatter Data Point

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 floodplain delineation. It can only be used in plan view.
