SMS:Raster Data Workflow

To import GIS in to SMS, use the following steps:

1. Import raster images.
Raster data is imported into the GIS module in SMS. Use the Open command to import raster data files such as DEMs, KMZ files, and gridded elevation formats. Files can also be imported with the "drag and drop" option.

2. Add images properties.

1. Register images. Right-click on the image object in the Project Explorer and select the Register Image command. Use the Register Image dialog to set image geo-referencing. 2. Set 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.

3. Adjust images.

1. Adjust image transparency. Right-click on the image object in the Project Explorer and select the Transparency command. Using the Layer Transparency dialog, set the transparency for the image. 2. Smooth a raster image. Right-click on the image object in the Project Explorer and select the Convert To | Smoothed Raster command. Use the Raster Smoothing Options dialog to specify how the raster image data values should be smoothed. Save the new smoothed raster file. 3. Trim the image. Select a coverage (or create a new coverage) in the Map module. Select the Create Feature Arc tool and draw a closed set of arcs. While the arcs are selected, go to Feature Objects | Build Polygons. Use the Select Polygon tool to select the polygon just created. Right-click a image in the GIS data and select Convert To | Trimmed Raster. Save a file with the trimmed data. 4. Resample a raster image. Right-click on the image object in the Project Explorer and select the Convert To | Resampled Raster command. Use the Resample and Export Raster dialog to specify how to resample the image data values. Save the new resampled raster file. 5. Merge mulitple images. Select two or more image items in the Project Explorer by holding down the Shift key while selecting each item. Right-click on one of the selected objects and select Convert To | Merged Raster. Save a file with the merged data.

4. Convert raster data.
Convert to map, grid, or scatter modules. Interpolate data to scatter module, grid module, mesh module, or map coverage.
