To use raster data in to WMS, use the following steps:

1. Import raster images.
Raster data is imported into the GIS module in WMS.
  1. Use the Open command to import raster data files such as DEMs, KMZ files, and gridded elevation formats.
  2. Files can also be imported with the "drag and drop" option.
2. Add images properties.
1. Register images.
  1. Right-click on the image object in the Project Explorer and select the Register Image command.
  2. Use the Register Image dialog to set image geo-referencing.
2. Set projections.
  1. Right-click on an object in the Project Explorer and select the Projection command.
  2. Set the horizontal and vertical projection using the Object Projection dialog.
  3. To set a global projection, use the Horizontal Projection dialog.
3. Adjust raster data.
1. Adjust image transparency.
  1. Right-click on the image object in the Project Explorer and select the Transparency command.
  2. Using the Layer Transparency dialog, set the transparency for the image.
2. Smooth a raster image.
  1. Right-click on the image object in the Project Explorer and select the Convert To | Smoothed Raster command.
  2. Use the Raster Smoothing Options dialog to specify how the raster image data values should be smoothed.
  3. Save the new smoothed raster file.
3. Trim the image.
  1. Select a coverage (or create a new coverage) in the Map module.
  2. Select the Create Feature Arc WMS CreateArcsTool.svg tool and draw a closed set of arcs.
  3. While the arcs are selected, go to Feature Objects | Build Polygons.
  4. Use the Select Polygon WMS SelectPolygonTool.svg tool to select the polygon just created.
  5. Right-click a image in the GIS data and select Convert To | Trimmed Raster.
  6. Save a file with the trimmed data.
4. Resample a raster image.
  1. Right-click on the image object in the Project Explorer and select the Convert To | Resampled Raster command.
  2. Use the Resample and Export Raster dialog to specify how to resample the image data values.
  3. Save the new resampled raster file.
5. Merge mulitple images.
  1. Select two or more image items in the Project Explorer by holding down the Shift key while selecting each item.
  2. Right-click on one of the selected objects and select Convert To | Merged Raster.
  3. Save a file with the merged data.
4. Convert or interpolate raster data.
1. Convert image data.
1. Convert raster data to feature contours.
  1. Right-click on the raster image and select the Convert To | Feature Contours command to create a new map coverage with elevation contours.
2. Convert raster data to feature contours at a specified elevation.
  1. Right-click on the raster image and select the Convert To | Feature Contours at Given Elevation command.
  2. In the Create Contour Arc dialog, specify an elevation and click OK to generate a map coverage with contours created along the specified elevation.
3. Convert raster data to scatter set.
  1. Right-click on the raster image and select the Convert To | 2D Scatter command.
  2. In the Raster → Scatter dialog, give the scatter set a name and click OK to generate the scatter set.
4. Convert image data to rainfall grid.
  1. Right-click on the raster image and select the Convert To | Rainfal Grid command.
  2. In the Resample and Export dialog, select the desired resampling options.
  3. Save the new grid and import it into WMS.
5. Convert raster data to DEM.
  1. Right-click on the raster image and select the Convert To | DEM command.
  2. In the Resample and Export dialog, select the desired resampling options.
  3. Save the new DEM and import it into WMS.
2. Interpolate image data.
1. Interpolate raster data to active coverage.
  1. Select and make active the map coverage where the raster data is to be interpolated.
  2. Right-click on the raster image and select the Interpolate | Active Coverage command.
2. Interpolate raster data to TIN.
  1. Select and make active the TIN where the raster data is to be interpolated.
  2. Right-click on the raster image and select the Interpolate | TIN command.
3. Interpolate raster data to scatter set.
  1. Select and make active the scatter set where the raster data is to be interpolated.
  2. Right-click on the raster image and select the Interpolate | 2D Scatter command.
