| SMS requires that a mesh or grid have bathymetry, or bottom elevation data, associated with the nodes or cells. By default, SMS creates a data set named "elevation" to store the elevation values. The data set being used to store elevations is referred to as the mapped data set.

| The Data menus in several modules include a command to use another functional data set as this mapped elevation function. When this command is performed the Select Data Set dialog opens to allow any existing scalar data set to be chosen. Any time step of any scalar data set can be used as the mapped data set and override the previous nodal elevation values. This is used mainly when interpolating new elevation data from scatter points.
