What resource is required to create a stream service?

Creating a stream service is specifically tied to the capabilities provided by the ArcGIS GeoEvent Server connector. This component is designed to support real-time event processing and allows for the integration of streaming data into the mapping and GIS frameworks. The GeoEvent Server facilitates the ingestion and processing of data from multiple sources, including streaming data from sensors or other real-time data feeds, making it essential for creating stream services.

In contrast, the other options focus on different aspects of GIS and data management. For instance, the ArcGIS Data Reviewer is primarily used for spatial data quality management and validation, while ArcGIS Image Server is tailored for managing and serving raster data and images. The ArcGIS Spatial Analyst extension provides advanced spatial modeling and analysis capabilities but does not focus on real-time data or stream services. Thus, the ArcGIS GeoEvent Server connector is the key resource required for establishing a stream service, enabling the utilization of live data within an ArcGIS environment.
