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 ArcGISScene first appears in the SceneView, you can focus the initial display at a specified view point with the tInitialViewpoint() method. You can also instantiate an ArcGISScene that's stored in a portal (such as ArcGIS Online) using its item ID or URL. With this approach, you typically first add a basemap layer and then one or more data layers.Īt the current release, scenes do not support basemaps that use a vector tile layer. You can instantiate a new ArcGISScene 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 with ArcGIS Runtime. 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.

Most applications contain a basemap layer to display geographic data with streets or satellite imagery, but you can also use data layers and graphics to display additional data. While the programming patterns are similar and many of the classes you work with are the same, maps are designed for working with geographic data in two dimensions (2D) and scenes in three dimensions (3D). They can be opened, edited, and shared across the ArcGIS system and beyond. Maps and scenes provide interactive displays of geographic data that enable you to visualize and explore patterns, answer questions, and share insight.
