feature

A feature is a single record, also known as a row, that represents a real-world entity. Features can be composed of a geometryA geometry is a geometric shape, such as a point, polyline, or polygon, that contains one or more coordinates and a spatial reference.Learn more (pointA point is a type of geometry containing a single set of x,y coordinates and a spatial reference.Learn more, polylineA polyline is a type of geometry containing ordered point coordinates and a spatial reference.Learn more, or polygonA polygon is a type of geometry containing an array of rings and a spatial reference. Each ring contains an array of point coordinates, where the first and last point are the same.Learn more) and attributes or only attributes without geometry, and are typically stored in a feature layerA feature layer (client-side) is a data layer that can access and display features from a feature service that has the same type of geometry and attribute fields.Learn more, tableA table is a non-spatial dataset in a feature service. All records in a table share the same set of fields.Learn more 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 serviceA feature service is a data service that provides access to spatial and non-spatial data in feature layers, feature layer views, and tables.Learn more, but can also be stored in other data sourcesA data source is a service or file containing geographic data that is accessed by a data layer.Learn more including ShapefilesA shapefile is a vector data storage format that contains geometry and attribute data for geographic features. It can also include spatial and non-spatial indexes.Learn more, GeoJSONGeoJSON is an open standard for representing geographic information in a JSON file. It is commonly used for sharing data between web services or manipulating vector data in the browser.Learn more files, and GeoPackagesA geopackage is an OGC spatial data storage format that can contain multiple datasets of geographic features, non-spatial tabular data, and raster data.Learn more.
