I want to publish a series of 8-bit unsigned raster datasets that represent land cover as image services on my ArcGIS server. I am able to publish the raster as an image service, but none of the attributes are carried from my local raster dataset into the ArcGIS server geodatabase. How do I publish a raster dataset with the attributes so that the attributes can be exposed in a popup in a web app or AGOL web map?
I've created an example image service here. You can pull the image into ArcGIS desktop or AGOL, but there are no attributes associated with the raster image.
