Sentinel 2 Imagery Viewer
Kathleen Denson
We did notice such issues sporadically on AGOL as well - sometimes it works on old viewer, but not on the old, sometimes the other way around.
We have tried troubleshooting with them as well, but with no success and the comment you provided (i.e. Javascript) seems the issue is on their side.
Sentinel Hub OGC APIs are in line with standard and they should work everywhere.
Thanks so much for getting back to me Grega. I have an open support case with ESRI, not sure the best way to get you all in touch with them. If possible, please email me jlde...@southernco.com so I can potentially provide them a way for you both to troubleshoot this issue. I have some logs from the developer console that may help as well.
So I spoke to an ESRI support analyst regarding this issue and we resolved this by removing the domain -hub.com from the list of Trusted Servers in the security settings in our AGOL account. Removing that resolved the issue and the Sentinel imagery services are now correctly displaying in the old AGOL viewer, the new AGOL viewer, and in ArcGIS Pro. Hope this is helpful to anyone else running into this issue but doing that seems to have resolved this issue for now.

Megan,
To achive this, you have to enable "Individual Image Search", specify the Sentinel-Layer and the AquisitionDate Field. I have created and attached a short video that might be easier to follow than a lengthy text. Plus the dummy app shown in the video will be available for a few days. The control with the 3 vertical bars opens the UI to select a specific date available in the extent chosen.
Hope this helps!

the ImageService has all information to use time - as you clearly state - but it prevents users to enable time slider functionality by not having "use time" activated in the Service properties to avoid "un-aware" use that might result in senseless processing and searches blocking other users from proper access. The new Imagery Apps now work with another method and selector. Try to use for example the new:
You have a good point. There are advantages and disadvantages of making the layers time aware. The issue has been that when time aware some app default to the earliest time and this does not work well for such services. Also the standard time line tools are not very effective at working with images with such disparate times. Hence the suggestion to use the time selector tools. Note there is now a image/time selector in the WebMap Viewer as well as in Pro and using Web Apps (see WABIS) and the new Imagery Configuration templates. The Sentinel service is currently Beta status we will look to possibly change the setting to time enabled (but keep default as off) for the release which should happen relatively soon. I'll add your name to the 'enable time' vote.
@GuenterDoerffel I am working with the imagery viewer apps, but am not seeing the option to find images by date. See screen shot and configurations below. Is there a way to enable this in the updated viewer? Thank you!
Since 2001, the USGS Global Visualization Viewer (GloVis) has been available to users for accessing remote sensing data. In 2017, it was redesigned to address changing internet technologies. With easy-to- use navigation tools, users can instantly view and download scenes.
This viewer allows you to:
- Use existing EROS Registration System (ERS) credentials to sign in
- Narrow down results by limiting your parameters on the Interface Control
- View multiple scenes at once and step through time using the controls in the lower right-hand corner
- View metadata and download the full-band source imagery
- Adjust settings to customize the user experience
Release Notes:
- Landsat Collection 2 Level-1 products on GloVis are available as a .tar.gz bundle download that includes all files associated with a scene. Or choose which band/files desired in a download. The different options are displayed in the Scene Download Options section. The list of possible files will vary depending on Sensor and Product. More information can be found in the document GloVis Landsat Collection 2 Download Options Help
Media Map includes a swipe tool that can be configured when in full setup mode. Open the Interactivity section, then click Modify. Toggle the Swipe tool on and select the leading and trailing layers. You can also configure the swipe direction and position.
This second Media Map swipe example shows NOAA sea level rise and adds configuration options to toggle layer visibility across multiple layers, each showing different sea level rise inundation areas. It also adds an information panel, fullscreen button, and bookmarks.
Imagery Viewer is an ArcGIS Instant App that supports both express and full setup modes. It allows users to visualize, explore, and interpret imagery through time and space. It includes tools for navigating through time, recording locations, measurement, and more. When using maps with two or more imagery layers, Imagery Viewer can be configured with a swipe tool that enables users to compare the layers.
In express setup mode, go to the Interactivity section. Toggle the Swipe Tool on and select the leading and trailing layers. You can also configure the swipe direction and position when in full setup mode, shown below.
View the example map used in the app. Note that because the map uses subscriber content, you will be prompted to authenticate with your ArcGIS account. For more information, see the Imagery Viewer item overview.
Atlas is an ArcGIS Instant App that can be configured with a group of content or individual maps or layers for viewers to explore. The app can be configured with tools such as a basemap gallery, measure, sketch, 2D/3D toggle, and more. Viewers can add layers, adjust transparency, view data as a table, and export the map as an image or PDF.
National Geographic MapMaker, intended for educators and students, is an example of a fully configured Atlas Instant App. Click Open map to choose a map, then click Map layers to open the Map layers pane. Note the MapMaker Help link in the upper right of the app.
Portfolio is an ArcGIS Instant App that allows you to showcase different types of ArcGIS Online content in one app. For comparisons, you can use a collection of maps showing different content that the viewer can interactively choose. It supports multiple layouts; configure with a carousel, tabbed, or accordion layout to display your content.
The app has been configured so that all maps open at the same location and it includes advance and play buttons in the upper right. A layer tool has also been added so you can view the basemap beneath the imagery.
Exhibit is an ArcGIS Instant App that can be used by app authors to tell a linear, interactive story with a single map. App viewers can move through slides defined by the app author to gain new information about the map and its data. While designed for presentations, it can also be used to compare content in maps.
In express setup mode, new slides were added that toggle the layer visibility between the historical map and underlying basemap. Slide notes were omitted but could have been used to provide details about the maps shown.
Compare is a configurable app template that supports the side-by-side or stacked comparison of two maps or scenes. It can be configured to compare two scenes, two maps, or one of each. The two views can be linked or unlinked depending on whether you want to view the same location.
Open the Hamburg 2D/3D Compare configurable app shown below, which uses both a 2D map and 3D scene. Pan, zoom, or tilt to compare the two, or click and hold the comparison slider to change your map focus.
The widget can be configured in a variety of ways. You can choose vertical, horizontal, or spyglass swipe mode, and can set the direction, color, and which layer in your map to swipe. Below is shown the configuration used in the sample app.
Open the Czech Land Survey Web AppBuilder app. Since the app is configured with the swipe tool enabled and desired layer already set, all you need to do is grab the handle and swipe. The swipe tool is located just beneath Search in the app.
ArcGIS Experience Builder lets you deliver responsive web experiences without writing any code. You can create apps and/or pages that contain 2D and 3D maps, text, and media. Experiences can focus on one type of content or can combine and link many types of content to create a complete experience and destination for your audience. Experience Builder can be used to build experiences that contain multiple maps, 2D or 3D, that can be synced.
Experience Builder includes a Swipe widget that can be configured in a variety of ways. You can also build an experience that compares maps using triggers and actions. Examples of each are covered below.
The Swipe widget allows you to compare layers and maps. The widget transitions from one map or layer to another by moving, or swiping, a divider across the map. The Swipe widget can be found in the Insert widget gallery, drag and drop it onto into your experience, then use the Content and Style tabs to configure the widget as desired. For more information, see Swipe widget.
Open the USA Aquifers and Current Drought Conditions experience shown below. The experience has been configured using a single map with two layers. The swipe tool is centered and activated automatically when the app is opened.
