Spatial Analysis with Real-Time Data in ArcGIS Pro 2.4

Early warning or assessment of potential damage is crucial for emergency response management to save lives and mitigate damages. Maybe you are an emergency management professional who is trying to make decisions on how to mobilize resources or wanting to send out warnings as a hurricane is moving in or floodwater is rising along rivers. Performing spatial analysis automatically as real-time data comes in will help you tremendously in your decision-making process.

This blog provides a sample ArcGIS Pro add-in and an example that simulates a use case in which all US counties affected by a hurricane are put on a map and charts are updated to show the affected population. And this all happens automatically with real-time data. Follow these steps:

Real-time spatial analysis
Computes affected counties and population using real-time hurricane forecast

The chart gets updated with the number of people who could be affected by the hurricane. You can click the 04. Select Affected Counties button again to stop this real-time analysis.

I have used a stream service that simulates this scenario using Hurricane Florence data. The sample code, data, and ArcGIS Pro project can be accessed at
