Hey @GilMastrapa ,  Do you know if you are using dynamic or tiled imagery layers? The update will only work on dynamic image collections. So if you are not using the image collections, the update is not supported. As a question about your workflow, how large are the files that you are changing out every few hours? ... View more

The updating of an existing imagery layer in ArcGIS Online is something that is only available currently as a dynamic image collection, but depending on the workflow, size, and the update schedule perhaps smaller .crf based imagery layers that can be deleted and replaced may work in the meantime. It all depends on the desired workflow and usage. The multidim process I described will unlock the data in map viewer to be visualized similarly to what you can with other netCDF based or other multidimensional data. If you are not as interested in using those tools like you see here.    Then the image collection with the image filtering may be desired. Feel free to reach out to discuss some more and work through your workflow.    ... View more

Hi @NigelBerjak , Is that layer public?  Or simply on ArcGIS Online within your organization? If you share its URL I can be specific, but here is some general stuff. Depending on they type of layer, enabling the pop-ups on that layer should reveal their pixel values if they are a imagery layer from ArcGIS Image for ArcGIS Online or an image service. If the layer is a tile cache or map image, then the pixel values will not be visible.  Here is a map image layer (map service) so this one will not have access to the pixel values.  A quick reminder is looking for the Pop-ups button amongst the properties for the layer. As you can see here the pop-ups are not available.  The layer I used was from ArcGIS Image which makes all the cell/pixel values available. You can see the icon for the layer is a little different.  So if you do not own the layer, but want to see the pixel values, you have to enable the pop-ups here.  If they are available based on the layer you have selected. So not all layers have same qualities or abilities, but take a look at ArcGIS Image layers if you want to see those values. In this blog, you can read more about some of the advantages.    ...

Hi @NigelBerjak , I hope that you were able to access the pixel values through ArcGIS Image for ArcGIS Online. Access to the pixel values are a standard for both types of imagery layers in ArcGIS Image for ArcGIS Online.    ... View more

Hi Alessio,  I am curious about your need of the image collection. The multidim layer in ArcGIS Online created by ArcGIS Image should work fine and allow you to access the information. If you want to see one in action, then I humbly recommend this ArcGIS Learn lesson on coral bleaching, the layer itself is located here if you want to add it to a webmap and see a tiled imagery layer with multi dim info. A dynamic image collection is not necessary to access the underlying data. When you have multi dimensional data in ArcGIS Online through ArcGIS Image, then you should be able to access the slices as you would in ArcGIS Pro.  In terms of the overwriting, I suppose this will be a 'live' layer with additional updates? Is that the case?  The multidimensional info can be accessed in map viewer.  You can select any slice in the multidimensional data.  Just let me know if you have any questions about the process. . ...

Hey @rachelm & @AlessioDiLorenzo ,  Alessio - So it seems there are a few things going on so let me dive in a little. For the first question about Multidimensional data. When you are creating your multidimensional data, are you following the instructions to make it multidimensional here? The rough steps are : Create a Mosaic Dataset Add the input images to MD Create MD fields to populate in MD Run Build Multidimensional Info tool.  This will create the .crf raster ready for your next steps. If created successfully, then you should see the Multidimensional options in ArcGIS Pro when you add it to a map. That .crf can be added as an imagery layer in ArcGIS Image for ArcGIS Online.  Rachel-  For the Build Multidimensional Transpose tool to work, the required input is a multidimensional input image. It sounds as if the data being input is not multidimensional. The error posted indicates that the .crf is required because that format supports being multidimensional. If you follow the same steps indicated above to create the multidimensional crf before, then your process should work as well.  Let me know if either of you have any follow up questions.  Thanks  ...

Good work Bruce! Sorry I missed this message. There is a two step process to fully enable it. Great catch. ... View more

Ok so what you are looking to do at this point is better served using Image Server. You could create a mosaic dataset in ArcGIS Pro, add the fields that you are looking to create and populate them with the necessary information. Then you could use ArcGIS Pro to publish the mosaic dataset with the fields you desire. However, if you were to try and update them, then that would be an issue. Image server is capable of having a 'live' mosaic dataset, where the image service could be updated as much as you like that way.  ... View more

The Image collection layer configuration is a Dynamic Imagery layer, which can maintain the attribute table. However, for out of organization sharing, only Tiled Imagery layers will work for that. I am just curious about your workflow and type of images. From your previous description, I wasn't sure if you had aerial images or since you said user submitted, it made me think that they were pictures.  Perhaps if you explained what types of images you had, then I could make a recommendation.  ...
