The spatial reference should be selected such that no coordinate system boundaries exist within the extents of the required image service definition.

5. Click Select.
6. Navigate to and choose a projected or geographic coordinate system.
7. Click OK to close the Spatial Reference Properties dialog box.
8. Click the Service type arrow and click Elevation.
9. Click the Visualization method arrow, choose a method, then fill in the remaining parameters; otherwise, click the As an elevation image service button.

20. Click the Select the input browse button and choose the file or folders containing the raster data.
21. Optionally, check Use this spatial reference for all input data to use the spatial reference you define and click the button to choose the desired spatial reference system.

    If unchecked, the spatial reference system defined with the raster is used.

22. Optionally, click Yes if you want to add additional data to your image service definition and click Next. This takes you back through the steps you have already completed to define additional data and any enhancements.
