Editing the NoData value in a raster process definition file

手順:

1. If you do not have an existing image service, create a new service and add your raster data.

   If you use the New Image Service Wizard, uncheck the Generate overviews and Compile the service for publishing options.

2. Open the <raster>.RPDef file located in the <your_image_service>.ISDef\RPDefs folder in a text editor.

   There is a separate .RPDef file created for each raster dataset in your image service (unless you added it using a Tiled raster type). This file has the same name as the RasterID entry in the service table.

3. Type the number representing the transparent value between the NoData tags as shown below.

4. Save and close the file.
