ArcGIS Pro 2.4 introduces its real-time API for real-time analysis. This opens up a lot of possibilities for developers to work with real-time data and integrate it with the rest of the ArcGIS Pro ecosystem. You can perform simple exploratory task or very complex spatial analysis such as flood forecasting with real-time data, or send out notifications via email, text etc. as incidents happen.
Here are some examples:
As a taxicab drives down on a street, you can find all nearby coffee shop locations, and display them in a pane.

You can—for security reasons—find the areas in a 3D space that are visible from police cars.

You can define a geofence and send alerts as vehicles enter or leave any restricted zone.

Or you can automatically perform spatial analysis to find all the counties and the total population that will be affected by an approaching hurricane.

In short, the real-time API in ArcGIS Pro SDK for the Microsoft .NET Framework allows a developer to react as features are streamed in real time, by subscribing to a stream layer. Stream layer is a relatively new layer type—introduced in the ArcGIS Pro 2.2 release just over a year ago—for consuming real-time data from a stream service. This API is very powerful and easy to use and gives developers absolute control and flexibility.
A sample Visual Studio solution, with sample code for above mentioned use case, and an ArcGIS Pro project with data can be downloaded from ArcGIS Online – https://arcg.is/0jH09i.
Actually the heavy reliance on the ribbon for tool access is fundamental flaw in the new UI. ArcMaps floating toolbars enabled one click to access any tool. Now every action requires a minimum of two clicks. Even when in the general context of the toolset itself (geoprocessing, labelling, editing etc). The other issue is that most tools are unresponsive on the first click in the map space. Take for example georeferencing, in most instance you need about 4 tools on the geoprocessing toolbar, but the ribbon runs off and hides everytime you select a tool, so a tool switch on… Read more »
Thank you for sharing your perspective, Simon.
I suggest you might want to head over to the Ideas site, there is already discussion around the topics you describe. https://community.esri.com/ideas/13935-arcgis-pro-option-to-enable-dockable-toolbars-and-menus
We have now 2022, Arcgis Pro 2.9.1. It is, concerning the GUI, now something like MS Office or Acad. Where you can make Acad look & feel like in 2006, and MSO not. I completely agree with Simon Watkinson. But not only you have now to do 2 clicks (or more) on many actions where you previously needed one, you also have to spend much more time to configure your workplace, which is a piece of cake in Arcmap. And you have to scroll and scroll, because someone decided to enlarge the space between items in the TOC. If I… Read more »
This is a great idea. Does this work with 2.8.3? and/or 2.9.3? Thank you.
Yes the UI configuration file in the download works even in ArcGIS Pro 3.0.
