feature

A feature is a single record, also known as a row, that represents a real-world entity. Features can be composed of a geometry (point, polyline, or polygon) and attributes or only attributes without geometry, and are typically stored in a feature layer, table or a feature collection. The geometry represents the location and shape of the real-world entity; the attributes represent the fields and values that describe the entity. Applications can access features from a feature layer, table, or a feature collection to visualize the feature's geographic and attribute information, execute spatial queries, perform analyses, or make edits to the feature's data directly. Examples of features include roads, fire hydrants, and property boundaries. Features are typically stored in a feature service, but can also be stored in other data sources including Shapefiles, GeoJSON files, and GeoPackages.
