Feature layers are web-based datasets that contain a group of similar geographic features (for example, buildings, parcels, cities, roads, and earthquake epicenters). Features can be points, lines, or polygons (areas) and are used in Insights to create maps, charts, and tables; perform spatial and nonspatial analysis; create filters; and share results. The feature layers you use in Insights can be either hosted in your organization or accessed remotely.
In Insights, feature layers are available from the Datasets tab on the home page or from the Content, Groups, Organization, Living Atlas, and Boundaries tabs from the Add To Page window.
Hosted feature layers
Hosted feature layers are feature layers that are stored within your organization's data store. These are layers that have been created in or published to your organization by you or members of your organization.
Remote feature layers
Remote feature layers are stored outside of your organization's data store. One commonly used example of remote feature layers is Living Atlas layers, which can be used by Insights but are hosted by ArcGIS Online.
