Data

Hosted data servicesData 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 provide a way to store, manage, and access your own geographic data for maps. You can store data in ArcGIS as features, vector tiles, and/or map tiles.

Feature data

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 allows you to store, access, and manage collections of 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. Each collection is known as 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. You can access features in a feature layer with a SQL and/or spatial query. Features can be returned in JSON, GeoJSON, PBF, and other formats. To create a feature service, you import data with the ArcGIS portalArcGIS portal, also known as a portal, is a website with applications and tools that can be used to create, manage, access, and share geospatial content and data. It supports security and authentication, developer credentials, content and data service management, user and group management, and site administration. A portal can be hosted in Esri's infrastructure or your own infrastructure.Learn more. You also use the portal to set the service capabilities, support for editing, access and security, and cache settings.

Tutorials

Add a feature layer as GeoJSON

Display and style GeoJSON features from a feature service.

Style a feature layer

Use data-driven styling to apply symbol colors and styles to feature layers.

Query a feature layer (SQL)

Execute a SQL query to access polygon features from a feature layer.

Query a feature layer (spatial)

Vector tile data

A vector tile serviceA vector tile service is a data service that provides access to vector tile data and a style definition.Learn more allows you to store and style your vector tile data in ArcGIS. Vector tile layers support the Mapbox Style specification and can be styled with the ArcGIS Vector Tile Style Editor. Vector tile services and layers are created from feature services by using ArcGIS portalArcGIS portal, also known as a portal, is a website with applications and tools that can be used to create, manage, access, and share geospatial content and data. It supports security and authentication, developer credentials, content and data service management, user and group management, and site administration. A portal can be hosted in Esri's infrastructure or your own infrastructure.Learn more tools. You can also use the portal to set the security and caching settings.

Map tile data

A map tile serviceA map tile service, formerly known as image tile service, is a data service that provides access to static, pre-rendered mao tiles. The tiles are typical in PNG format.
