ArcGIS Excalibur is a web-based, imagery application that enables users to search for, discover, and work with imagery. At the November 2021 release, ArcGIS Excalibur introduces a new tool called the Export Image tool to help export an image in a variety of ways for use in downstream analysis. The tool allows me to view a selected image as a snapshot, save the selected image, or even download the full resolution image.
In this blog, we will go through a workflow that shows you one of the many ways you can use the Export Image tool to support your image analysis.
Workflow
As an analyst, I need to help my manager find imagery for their daily briefings. Today, my job is to provide an image that can help visualize the potential size of containers at a facility of interest.
After exploiting my image collection, I have identified an image that will work for my manager’s briefing. I can go to the Tools menu and open the Export Image tool. Before I export my image, I need to Draw my Area over my exploitation work to define my export extent. I have a few options to choose for export. I can view image snapshot, which opens the image up in a new browser tab as a JPEG, and Save image snapshot, which downloads the JPEG of my drawn area. Both options are good for presentations and briefings.
The Download source imagery option will select all imagery and their corresponding files in the drawn area of interest and make them available for download. This option is good if I want to work the imagery in additional mapping applications.
Since I must share my image with my manager, I want to save the image as a snapshot. I need to provide a name for my file such as Potential Container Size at Facility of Interest. Now, I can export my imagery and it is available to use.
This is just one of the ways that the new Export Image tool in ArcGIS Excalibur helps you share your image-based work for downstream analysis. To learn more about ArcGIS Excalibur, visit our product page or read our documentation.
I am trying to implement this for my Org. I have followed along up until the configuration of the dashboard – step 5. How do I change the dashboard over to my own set of tables? Is it best to edit the json of the dashboard and replace the sample item id’s with my set? Also – to get the notebook to work – I had to comment out availble credits and assigned credits from the User Admin section of the notebook. Is this configured assuming we have turned on credit budgeting for the users – and if we haven’t… Read more »
Great stuff! We built a very similar dashboard and process for my company. We even made a StoryMap about it (Link below) . Dashboards are such a powerful tool that it can be used for non-spatial solutions as well.

This is really useful – thank you. Having set it up it up for our organisation’s account I’ve noticed a possible issue with the ‘FS Storage’ counter (and maybe some of the total credit measures used in other bits of the dashboard). The total number credits per month given in the FS Storage counter is much higher (almost 2x) than our total monthly credits usage as given by the ‘Overview’ tab in the ‘Organisation’ section of ArcGIS Online (which I’d consider to be the correct/definitive figure). Having had a bit of a search around, I’m wondering if it’s because the… Read more »
Hi Colin, thank you for the note. You are correct on the limitation. Attachments on fs storage is calculated differently, but the script currently does not account for that. When this script was originally developed, I didn’t take into account for your scenario. Having said that, this will be a useful note to share with the community so we understand the limitation. I will make sure to put this in. There should be a way to do this in the script (AGOL does it after all :)) If you (or anyone in the community) develop an enhancement for this –… Read more »
The notebook populates three tables:
But the instructions for updating the dashboard only requires changing the IDs for two of the tables. The user table does not appear to be used by the Dashboard. Is that correct?
Bonnie and Calvin: this is an excellent article! I am working on applying it for my organization. There is no longer an option to choose ArcGIS Notebook Python 3 Standard – 4.0. Instead, I can choose between 7.0 and 10.0. What would be causing that? @Calvin Kwon
I’m trying to implement this for my organisation and when running the notebook for the first (and subsequent) times, I get the following error :
I run this on ArcGIS Notebook Python 3 Standard – 11.0.
I have this same error. Any insight on resolving?
Excellent article! Exactly the item management solution we were looking for for our open data portal.
