  3. While the arcs are selected, go to Feature Objects | Build Polygons.
  4. Use the Select Polygon File:Tool SelectPoly.png tool to select the polygon just created.
  5. Right-click the raster data in the Project Explorer and select Convert To | Trimmed Raster.
  6. Save a file with the trimmed data.
2. Resample a raster image.
  1. Right-click on the raster 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.
3. Merge mulitple rasters.
  1. Select two or more raster items in the Project Explorer by holding down the Shift key while selecting each item.
