Layer types

You can use different types of data layersA data layer is a layer that references geographic data from a file or a service and is used to visualize the data in a map or scene.Learn more to access and display various types of data in your applications. Data layers can access ArcGIS and other data sources, such as open services, on-device data, and files.

Different data layers support different capabilities based on their underlying data sourceA data source is a service or file containing geographic data that is accessed by a data layer.Learn more. For example, an image tile layer provides geographic context with tiled imagery, while a 3D object scene layer enables you to interact with objects such as buildings, from a scene service or local scene layer package.

The ArcGISLayer class is the base class for all layer types. The type of layer you create depends on the type of data you want to display. The table below summarizes the data layers supported by the ArcGIS Maps SDK for Unity.
