Some layers cannot be displayed in a scene, such as ArcGISVectorTiledLayer and AnnotationLayer. For example, to display feature data you can create a FeatureLayer that references an online service (such as a feature service) or a supported local dataset. The type of layer you create depends on the type of data you want to display. The Layer class is the base class for all types of layers used in ArcGIS Maps SDK for. To learn more about scene layers, visit What is a scene layer? in the ArcGIS Pro documentation. Scene layers can contain one of four data types: points, point cloud, 3D objects, or an integrated mesh. Scenes can also contain scene layers enabling you to create advanced 3D visualizations. In addition to geometry, features have attributes that provide details about the entity it represents. 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. There are a variety of layers that can be added to a scene, each designed to display a particular type of data. LayerĮach layer in a scene references geographic data, either from an online service or from a local dataset. If an initial view point is not defined, the scene will initially display at a global scale. When the Scene first appears in the SceneView, you can focus the initial display at a specified view point by setting the Scene.InitialViewpoint property. With this approach, you typically first add a basemap layer and then one or more data layers. You can instantiate a new Scene object by creating a new scene and building it entirely with code. Layers can be draped on top of the surface, positioned relative to the surface or displayed based on their absolute values. Scenes extend the concept of a basemap by introducing a base surface that contains a collection of elevation sources. You can use the scene to change the display order of two dimensional layers as well as to control which layers are visible, and expose this functionality with user interface controls such as lists, check boxes, or switches. Two dimensional layers are displayed in the order in which they are added, while three dimensional layers are displayed using the layer's elevation information. SceneĪ scene contains a collection of layers. See Offline maps, scenes, and data for more information about implementing offline workflows in your app. You can create mobile scene packages using ArcGIS Pro, share them using your ArcGIS organization, or distribute directly by copying to a device. A scene can also contain datasets that enable searches for addresses or place names, networks for solving routes, and non-spatial tables.įor offline workflows (when you don't have network connectivity), you can open a scene stored in a mobile scene package. A scene contains a collection of layers including multiple data layers from online or local sources, a basemap layer that gives geographic context, and a base surface containing elevation data.
