I'm trying to put a drone-derived shaded relief raster on an ArcGIS Online webmap for inclusion in a StoryMap. I know that I can upload a hillshade raster derived from my DEM - this is the standard grayscale hillshade model created using Spatial Analyst. That's fine - but I really want a nicely colorized shaded relief raster. Super easy to create one symbolically in Pro - but no option to export it as such and no option to mimic that symbology in a webmap that I've seen as yet (there might have been a way to do it in the Classic viewer?).
Anyway - I'm looking for either a direct solution or a creative workaround. I'm beginning to think I'll have to do some janky thing like create a JPEG image, georef that, then upload that to Online and make it work. Too much work for something that should be native to AGO since it's child's play in Pro.
