This issue has resolved itself it seems. In both a web map and a Web App Builder app, popups report the pixel value and land cover type. ... View more

Tech support is suggesting 1) I try publishing a smaller raster with the function applied or 2)publishing the full size raster without the function. I will try this again soon. I'd be curious to know what they tell you to do if you call. ... View more

I think my scenario is similar. I've published an image service for a land cover raster (8-bit, 1-band .img file) that uses the attribute table raster function to provide access to the land cover classes and the symbology I want. I had to add Red, Green, and Blue fields to the raster attribute table and populate their values. I had overlooked this sentence in the help for the attribute table function: Additionally, if your [raster attribute] table contains fields named red, green, and blue, then values within those fields will be used like a color map when rendering the image. The identify tool in ArcMap reports the land cover class as well as the pixel value. Layer files and color maps seemed to wipe out raster attributes for me as well. Now I just need to get ArcGIS Online popups to read the raster values. So far, I haven't gotten the AGOL popup to work for the land cover layer (it works for LiDAR and other image services though).   ... View more

The values are not coming through correctly for Height Above Ground when I use a shaded relief function. I must be missing something here. Should any functions be set on the mosaic dataset or should everything be stored in an rft.xml file and published with the image service? ESRI technical support provided the workflow below for a bare earth hillshade and a surface model hillshade to report elevations in feet, but it doesn't seem to work for height above ground. Also, all functions in the provided workflow are applied on the mosaic datasets, not the image services. I'll admit it, I'm confused. Thanks for sticking with me here. Hey Greg, I just want to know that I was able to follow those instructions that I sent in the previous email to publish an image service as a hillshade display, but still reference the feet - meter function pixel values referenced from the  mosaic dataset. The way to do this is outlined in the workflow, but some main points to take note of are as follows: - Mosaic 1 needs to have the feet to meters function applied to it. - Mosaic 2 needs to contain mosaic 1 (ie. Add rasters to mosaic 2 > Add type as Table > Load Mosaic 1) - Created referenced mosaic dataset from mosaic 2 and apply hillshade function to referenced mosaic. - Publish referenced mosaic as image service. Set referenced image in service editor under "Catalog" to mosaic 2. The result will be a hillshade effect, but pixel value in identify will have the elevation values display properly. As mentioned, this workflow can be found here: http://desktop.arcgis.com/en/arcmap/latest/manage-data/raster-and-images/wkflw-elevation-part3.htm ... View more

I have a question related to my previous GeoNet thread on image services and functions. I’ve published an image service of a digital surface model that has a function to change the view to height above ground. The popup has been configured to show the Item Pixel Value but that always seems to return the raw LiDAR point value instead of the height above ground (calculated through an arithmetic function as surface model height minus bare earth elevation multiplied by 3.28 to convert meters to feet). For example, the building shown in the attached image is 16 feet tall. The 77.05 shown is the top of building height plus ground elevation in meters, so my arithmetic functions are being ignored. My question is, when changing from one image service function to another in a web map, is it possible to have the Item Pixel Value change in order to reflect the new pixel values? I appreciate any help you can offer.  ... View more

Cody, I changed my image service back to dynamic display and the renderer is now available in the ArcGIS Online map. Is this the only way to get access to the renderer? Performance is decent without using the cache, but I'd like this to be as fast as possible. Thanks. ... View more

Thank you for looking into this. I'm not sure what is different from 2-3 weeks ago when this was working. ArcMap has no problem accessing the functions through Properties-->Server Functions tab as long as Enable Cache View Mode is off. ... View more

Cody, Thank you for your quick reply. The image service was published from the catalog window as you describe in your last paragraph. I added the raster function in the UI and set it to draw the shaded relief by default. I think the problem may be that I already have a shaded relief function on my mosaic dataset to begin with and probably didn't need to add it again on the image service. By the way, some of your presentations and documentation are what got me this far, so thank you for that! ... View more

I'm using an arithmetic function on LiDAR data in a mosaic dataset that has been published in an image service. The function multiplies my native data (UTM Zone 18 NAD83, NAVD88 elevations in meters) by 3.28 so the identify tool will be report units in feet. Does this affect tools like viewshed and watershed since my horizontal coordinate system is still in meters? The exaggerated appearance of my resulting hillshade makes me think the vertical dimension will be 3.28 times what it should be. ... View more

I'm having the same problem.  I've shared many tile packages in the past, but this issue has arisen in the last week or so.  The results window shows that the tool completed, but it has contradictory messages about its success.  What did it do for 1 hr 40 min 33 sec? ... View more
