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.  ...

Hi Michael, So you are looking to create a collection of images in an online layer and then associate them with particular attributes? I would think you would probably rather use an app like Field Maps, Quick Capture, or Survey123 to use the ability to upload a photo as an attachment. With those apps, you can easily control the attributes and populate them how you feel. An image collection functions more like a mosaic dataset, where the attribute table contains information about the individual images used in the mosaic, but perhaps not if the images are not overlapping and contribute to one 'mosaicked' image.  Here is an example of using ArcGIS QuickCapture for photo inspections.  ...

Hey Michael, You can add images through the Python API to ArcGIS Image for ArcGIS Online. You can create and analyze the imagery layer in ArcGIS Online through the API.  arcgis.raster.module  Take a look there and see if that is what you were looking for. ... View more

Thanks for the JSON. Ok so you created a Dynamic Imagery layer via ArcGIS Image for ArcGIS Online and then turning that into a tiled service that doesn't display at all zoom levels. I am curious about your workflow.  Why are you creating the tiled cache on a imagery layer? Is there a particular workflow you are looking to use?  The imagery layer is designed to be available to you in any online application ( Map Viewer - ArcGIS Online), App (Field Maps,Survey123, etc) , or desktop application (ArcMap, ArcGIS Pro). If you are chasing performance perhaps a Tiled Imagery layer will meet those needs.  ... View more

Hey Gareth,  So to recap, you published the image via ArcGIS Image for ArcGIS Online? If so what can you indicate if tiled/dynamic and which layer configuration you chose? Or indicate what method you used to publish it? Also what do you mean 'they are all available, but not there.' Are you talking about overviews not being published? ... View more

Hi Ross,  I apologize for the delay. So I was meaning something like this. Since the training manager allows you to create individual samples that are within the same class, then I meant you could 'group' or 'collapse' them as I have in this graphic.  After re-reading your statement, I don't think that is what you want to do. So I would propose this instead, perhaps a different way of doing this. I would recommend trying to take advantage of some different application. Since what you described is more of a observation, than an image classification training sample you could take you imagery (thinking it is an image or imagery service/layer) and then use something like Field Maps or Quick Capture to collect the data as you desire. You could publish your imagery data in ArcGIS Image for ArcGIS Online.  I know it is thinking a little outside the box, but if you used quick capture for example, you could make the 'types of animals you are observing.' Let's say duck, deer, rabbit, squirrel, bird for rough examples, then you could make a quick capture app with each of them as the 'observation' in a feature layer in ArcGIS Online. Then when you found a bird, marked it ion the image - then it would record it as a bird and then give it a number. You could then quickly spin thru the image and have the data you are looking for with numbers attached.  What you are doing with the training sample is not as designed. The multiple selections would be taken in a group to generated a Esri Classifier Definition, which would then be used to classify an entire image. From your description, the samples have to be found with intense scrutiny to assess what type of animal is there. So if you were to take your training samples and then create the .ecd, then I am not sure the classification is valid, since you said each of the observations are of different animals.  The training sample manager will allow you to quickly create a point file, but not in manner you are wanting I think.  Here is the info on Quick Capture and Field Maps. I think they maybe worth your time. I know each is a 'mobile' app, but on an Ipad or similar device you can load up the imagery layer you want and then push that through and zoom/classify at your leisure. Just be sure not to use the gps of the device you are using.  ... View more

Hi RossSmail, Out of curiosity, can you describe the workflow you are using here?  If they are the same class, then why not combine them from time to time?  Were the training samples pre-generated or automated and require you to confirm if they are valid? I can definitely see where this could be hard to manage, but wanted to know more about your workflow for this process.  Please let me know.  ... View more

Well done explanation.  Thanks a bunch! ... View more
