Editing the NoData value in a raster process definition file

Legacy:

ArcGIS 10 is the last release of the stand-alone ArcGIS Image Server product. The image service definition (.ISDef) has been replaced by an improved geodatabase data model—the mosaic dataset—which can be published as an image service using the ArcGIS Server Image extension.

Steps:

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.
