Add scene layer with elevation

View on GitHub

Sample viewer app

Add a scene layer to a scene.

Image of scene layer

Use case

Each scene layer added to a scene can assist in performing helpful visual analysis. For example, if presenting the results of a shadow analysis of a major metropolitan downtown area in 3D, adding a scene layer of 3D buildings to the scene that could be toggled on/off would help to better contextualize the source of the shadows.

How to use the sample

Run the sample to display a scene service with an ArcGISSceneLayer. Pan and zoom to explore the scene.

How it works

Create an ArcGISScene having a BasemapStyle.ArcGISTopographic.
Create a SceneView and set the scene to the view.
Create an ArcGISSceneLayer using a data source URI: ArcGISSceneLayer(Uri).
Add the new scene layer to the scene as an operational layer with scene.operationalLayers.add(sceneLayer).

Relevant API

ArcGISScene
ArcGISSceneLayer
SceneView

About the data

The scene launches with a northward view of the city of Brest, France (SceneServer). A 3D scene layer representing buildings (some textured) is used as an example.

Additional information

This sample uses the GeoViewCompose Toolkit module to be able to implement a Composable SceneView.
