The Summarize Nearby tool requires what to measure drive-time or drive-distance?

The Summarize Nearby tool, when used to measure drive-time or drive-distance, requires an ArcGIS Online organizational account with Network Analysis privileges. This requirement is essential because the tool relies on the network analysis capabilities provided by ArcGIS Online. These capabilities facilitate the calculation of travel times or distances based on a specific network, such as roads or pathways, which is crucial for accurately summarizing nearby features.

In this context, an organizational account ensures that the user has access to the robust network analysis features necessary for these measurements. The privileges associated with such an account allow for the usage of routing and analysis services, enabling accurate assessments based on the underlying data and network conditions.

Other options do not provide the same necessary capabilities: while premium ArcGIS accounts may offer access to additional features, they do not specifically ensure network analysis functionality. A locally installed Business Analyst dataset could provide market analysis features but does not inherently support the network-based calculations. Similarly, simply having a registered GIS data source does not equate to having the ability to perform drive-time or distance analysis without the required network analysis privileges that come with an appropriate account.
