SMS:Zonal Classification Workflow

To create an classification zones in SMS, use the following steps:

1. Create or import data for classification criteria.

1. Import elevation data. If geometric data with elevation data has not already been imported, do any of the following: 1. Import map data. Use the File | Open... command to import map data such as Map files, boundary ID files, or boundary XY files. Alternately, drag and drop the file into the Graphics Window in SMS. 2. Import GIS data. Use the File | Open... command to import GIS data files such as Shapefiles, MIF/MID files, Lidar files, or raster files. Alternatively, drag and drop the file into the Graphics Window in SMS. 3. Import scatter data. Use File | Open... to open files with scatter data such as scatter point files, ASCII dataset files, binary dataset files, tabular data files, or XYZ files. Alternatively, drag and drop the file into the Graphics Window in SMS. Use the File Import Wizard to specify how to import the data. 4. Import CAD data. Verify the CAD file type is readable by SMS before importing it. SMS can import DXF and DWG files. Use the File | Open... command to launch the Open dialog (or drag and drop) to import the CAD files. The data should load in layers into the Project Explorer. 5. Review and set object projections. Right-click on an object in the Project Explorer and select the Projection command. Set the horizontal and vertical projection using the Object Projection dialog. To set a global projection, use the Horizontal Projection dialog. 2. Create materials in area property coverage. Create an area property coverage if one does not already exist. Create polygons in the area property coverage. Create material types. Assign materials to the polygons.

2. Use the Classification Wizard.
Use the 'Zonal Classification command in the Data menu in either the 2D Grid, Mesh, Quadtree, or Scatter module. Use the Classification Wizard to define criteria for classification.
