Layers

Maps and scenes use a collection of layers to display geographic data from a variety of sources and formats. These can include several basemap layers and data layers from online or local sources.

Each layer in a map references geographic data, either from an online service or from a local dataset. There are a variety of layers that can be added to a map, each designed to display a particular type of data. Some layers display images, such as satellite photos or aerial photography, others are composed of a collection of features to represent real-world entities using point, line, or polygon geometries. In addition to geometry, features have attributes that provide details about the entity it represents.

Basemap layers

A basemap layer is a layer that provides the overall visual context for a map or scene. It typically contains geographic features such as continents, lakes, administrative boundaries, streets, cities, and place names. These features are represented with different styles provided by the basemap layer service such as streets, topographic, and imagery. The style you choose depends on the type of application and the visualization you would like to create.

A basemap layer provides the visual foundation for a mapping application. It typically contains data with global coverage and is the first layer added to a map or scene. The main data source for a basemap layer is the basemap layer service. When a view displays a map, a basemap layer is the first layer to draw, followed by data layers, and then graphics.

The Basemap layer service provides a number of vector tile and image tile basemap layers that you can use to build different types of mapping applications. Each of the basemap layer styles is defined in an enumeration. For example, you can use the Navigation style to create an application that supports driving directions, or you can use Imagery to create an application that displays a real-world view of the earth.

Data layers

A data layer, also known as an operational layer, is a layer that can access geographic data from a data source. You use a data layer to display geographic data on top of a basemap layer in a map or scene. The data source for the layer can be a data service or a file such as a shapefile or GeoPackage.

A data layer provides access to geographic data that is displayed in a map or scene. Each layer references a file or service data source. The data source contains either as vector data (points, lines, polygons and attributes) or raster data (images). Different types of layers can access and display different types of data.

The data for a data layer is typically stored in the ArcGIS Platform as a data service. You can use feature services, vector tile services, and image tile services to host your data. Learn more in Data hosting.

A data layer can also be created from a dataset stored on the device. For example, data stored in a shapefile, mobile map package, or geodatabase. Learn more about using offline data in Offline maps, scenes, and data.

To add a data layer to a map or scene, you typically add imagery or tile layers first, and then polygons, lines, and points layers last. A map or scene controls the order of the layers, and the map or scene view combines the layers to create the final display.

Layer types

You can use different types of data layers to access and display different types of data in your applications. Data layers can access ArcGIS data sources and other types of data sources such as OGC data and files.

Different data layers provide different types of functionality. The functionality available is largely dependent on the capabilities of the data source. For example, a feature layer can access a feature service and perform queries, edits, and data export, whereas a vector tile layer can only access tiles from a vector tile service.

The AGSLayer class is the base class for all types of layers used in ArcGIS Runtime. The type of layer you create depends on the type of data you want to display. To display feature data (point, line, or polygon geometry), for example, you can create a AGSFeatureLayer that points to an online service (such as a feature service) or a supported local dataset. The tables below summarizes common types of layers available for your ArcGIS Runtime app.

Use API keys

An API key can be used to authorize access to ArcGIS Online services and resources from your app, as well as to monitor access to those services. You can use a single key for all requests made by your app, or assign individual keys for classes that expose an API key property. See API keys in the security and authentication topic for details.
