Scatter data can be used in GMS with the following steps:

1. Import scatter data.
  1. Use File | Open... to open files with scatter data.
    • Alternatively, drag and drop the file into the Graphics Window in GMS.
  2. Use the File Import Wizard to specify how to import the data.
2. Generate scatter data.
Scatter data can also be generated from data in other modules in GMS. Some options are:
  1. GIS to scatter.
  2. Map to scatter.
  3. Mesh to scatter.
3. Edit and modify scatter sets.
After a scatter set has been imported into GMS, it may require editing to be usable.
  1. Merge another scatter set into a selected scatter set.
  2. Create scatter points.
  3. Select and edit points.
5. Export tabular data.
Scatter TIN data can be exported as tabular data for use in other software.
  1. Use the Save As... command and select the "tabular data" file type.
  2. Use the Export Tabular File dialog to specify how the tabular data should be formatted.
6. Interpolate scatter sets.
For the topgraphic data in the scatter set to be included in the model run, the scatter set normally needs to be interpolated to the module being used. Multiple interpolation options are available, including:
  1. Linear
  2. Inverse Distance Weighted (IDW)
  3. Natural Neighbor (NN)
  4. Laplacian Interpolation (Cartesian grids only)
