feature service

A feature service is a data serviceData services, also known as hosted data services, are services created dynamically to store and provide access to your data in ArcGIS. Examples are feature services, vector tile services, map tile services, image services, and scene services.Learn more that provides access to spatial and non-spatial data stored as featuresA feature is a single record, also known as a row, that represents a real-world entity. It typically contains a geometry (point, multipoint, polyline, or polygon) and attributes but it can also contain just attributes.Learn more. Feature services can contain feature layersA 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 (with spatial data), feature layer views (with subsets of feature layer data), and tables (with non-spatial data). Client applications can use a feature service to query and edit data attributesAttributes are fields and values for a single feature or non-spatial record. They are typically stored in a database or service such as a feature service.Learn more, 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, related data, and attachmentsAn attachment is a file, such as a photograph (for example, a .png file) or a document, that is associated with individual features in a geodatabase or feature layer.Learn more, as well as to access and display features in a map or scene. A feature service supports querying data using both SQL and spatial relationships, and query responses in different formats such as JSON, 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, or XML. Feature services are created by importing data or by creating new feature layers through ArcGIS client APIs and tools.
