What is the best way to update the tools for this situation? Any real time feed with data at county level?
We would like to utilize geoevent and Insights for this purpose and are looking for an API.
Today ArcGIS Insights has a manual refresh option, as described below. In our upcoming June/July release we will have support for scheduled refresh of analysis.
Manage workbooks—Insights Get Started | Documentation
As it relates to a real time feed, we currently doi not have one in Insights, however, if connecting to the Feature Layer being created by GeoEvent while in the workbook, it will go back to the feature layer and pull the latest data. When sharing, and using cross-filters, the same. We have been discussing creating a real-time feed for a feature layer and it is marked in our backlog as a todo in the near term. Thanks for your question and great enhancement request.
