About the Add Data Wizard parameters
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 The image service definition (.ISDef) has been replaced by an improved geodatabase data model—the mosaic dataset—which can be published as an image service using the ArcGIS Server Image extension.
To add additional data to an existing image service definition, you can use the Add Data Wizard. This wizard can be used to add raster data, optimize the image service definition, enhance the imagery or visualize the elevation data, and compile the service. The Add Data Wizard is displayed when you click Image Service and click Add Data on the Image Service Definition Editor toolbar.
If you have opened a color or panchromatic service, the wizard panels that appear are the same as those in the New Image Service Wizard.
If you have opened an elevation service, the rest of the wizard panels will appear in the same order as those in the New Image Service Wizard.
