WMS:Scatter Data Workflows

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

1. Import scatter data.
Open scatter data files with File | Open.... Scatter data could be in the form of a scatter point file, binary dataset file, ASCII dataset file, etc.. Alternatively, drag and drop the file into the Graphics Window in WMS. Use the File Import Wizard to specify how to import the data.

2. Generate scatter data.
Scatter data can also be converted from a 2D grid in WMS.

3. Edit and modify scatter sets.
Use the data calculator to modify a scatter set by first making sure the scatter set module is active, then go to the Data menu and select Data Calculator....
The data set can also be manually modified. 1. Select scatter point. Use the Select Scatter Point tool to select an individual scatter point. Enter a number in the X, Y, or Z field in the edit window. Scatter points can also be moved by using the Select Scatter Point tool and dragging the point in the Graphics Window. 2. Create new scatter data point. Use the Create Scatter Data Point and click in the Graphics Window to create a new data point. 3. Edit scatter point data in a table. Right-click on the scatter point data set in the Project Explorer and select Properties.... Click Edit Values... in the Data Set Info dialog window. Manually edit the scatter point data, point-by-point, on the table in the Edit Data Set Values dialog.

4. Export data.
Go to File | Save As... to export the scatter set data. Alternatively, right-click on the scatter set in the Project Window and select Export Data Set... to bring up the File Formats dialog to export the scatter set data.

5. Interpolate scatter sets.
For the topographic 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 in the model run. Multiple interpolation options are available, including: Linear Inverse Distance Weighted Natural Neighbor (NN) Clough-Tocher
