Work with data sources

A data source loads static or near real-time data into a real-time analytic.

In real-time analytics, data sources load data used in conjunction with tools that require an ancillary spatial or tabular dataset to enrich, filter, join to, or calculate distance from events. When a real-time analytic starts, data from a data source is loaded once. To leverage dynamic data for these operations, a feed should be configured and used as join data in analytic tools.

The following data source types are available in ArcGIS Velocity:

• Standard Geographies
  • United States
  • World
• ArcGIS
  • Feature Layer
  • Feature Layer (archive)
• Cloud
  • Amazon S3
  • Azure Blob Store
  • Azure Cosmos DB
• Web and Messaging
  • HTTP Poller
  • Read a Local File from a Folder
  • RSS

Example

The following is an example of using a data source:

A GIS analyst configures a Feature Layer source in a real-time analytic to load United States Census Bureau census tract data to enrich incoming sensor observations with information about the census tract they intersect.

Add a source in a real-time analytic

You can add a source only to an existing real-time analytic. Complete the following steps to add a source to an existing real-time analytic:

1. Open the ArcGIS Velocity app.
2. Click Real-Time from the menu to access the Real-Time Analytics page.
3. Click the Create real-time analytic button, and then click Existing feed.
4. Select an existing feed and click Confirm to open the analytic.
5. Expand the configuration pane and click Sources. Choose a source type from the following categories:
   • Standard Geographies
   • ArcGIS
   • Cloud
   • Web and Messaging
6. Provide source configuration details.

   The configuration parameters vary depending on the source type.

7. Configure the schema, key fields, and polling settings in the same way for all source types.

The configured source is available in an existing real-time analytic. You can now add and configure tools to analyze the data and send the results to various outputs.

Edit a source

You can edit an existing source in a real-time analytic to adjust connection parameters, schema configuration, key fields, and polling settings. To edit a source in an analytic, double-click the source node to see additional details or click the edit button to access the source configuration wizard.
