Learn how to create and display a scene from a web scene stored in ArcGIS.
This tutorial shows you how to create and display a scene from a web scene. All web scenes are stored in ArcGIS with a unique item ID. You will access an existing web scene by item ID and display its layers. The web scene contains feature layers for the Santa Monica Mountains in California.
Prerequisites
The following are required for this tutorial:
- An ArcGIS account to access your API keys. If you don't have an account, sign up for free.
- Confirm that your system meets the minimum system requirements.
- An IDE for Java.
Steps
Open a Java project with Gradle
-
To start the tutorial, complete the Display a scene tutorial, or download and unzip the Display a scene solution into a new folder.
-
Open the build.gradle file as a project in IntelliJ IDEA.
-
If you downloaded the solution project, set your API key.
An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.
-
Go to your developer dashboard to get your API key. For these tutorials, use your default API key. It is scoped to include all of the services demonstrated in the tutorials.
-
In the IntelliJ IDEA > Project tool window, open src/main/java/com.example.app and click App.
-
In the
start()
method, set the API key property on theArcGISRuntimeEnvironment
with your API key. Replace YOUR_API_KEY with your actual API Key. Be sure to surround your API Key with quotes, because the parameter passed toset
is a string.A p i Key
App.javaUse dark colors for code blocks Change line Change line Change line Change line stage.setScene(fxScene); // Note: it is not best practice to store API keys in source code. // The API key is referenced here for the convenience of this tutorial. String yourApiKey = "YOUR_API_KEY"; ArcGISRuntimeEnvironment.setApiKey(yourApiKey);
-
Prepare files before coding the app
Modify the files from the Display a scene
tutorial so that they can be used in this tutorial: you will add imports, change the application title, and remove unnecessary code.
-
In IntelliJ IDEA's Project tool window, open src/main/java/com.example.app and double-click App.
-
Add the following imports, replacing those from the
Display a scene
tutorial.App.javaUse dark colors for code blocks package com.example.app; import com.esri.arcgisruntime.ArcGISRuntimeEnvironment; import com.esri.arcgisruntime.mapping.ArcGISScene; import com.esri.arcgisruntime.mapping.view.SceneView; import com.esri.arcgisruntime.portal.Portal; import com.esri.arcgisruntime.portal.PortalItem; import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.layout.StackPane; import javafx.stage.Stage; public class App extends Application {
-
In the
start()
life-cycle method, change the title that will appear on the application window toDisplay a web scene tutorial
.App.javaUse dark colors for code blocks @Override public void start(Stage stage) { // set the title and size of the stage and show it stage.setTitle("Display a web scene tutorial"); stage.setWidth(800); stage.setHeight(700); stage.show();
-
In
start()
method, delete the code for base surface, surface elevation, camera, and camera viewpoint. The web scene defines these characteristics, so you don't have to set them in your app.App.javaUse dark colors for code blocks // create a scene view to display the scene and add it to the stack pane sceneView = new SceneView(); stackPane.getChildren().add(sceneView); ArcGISScene scene = new ArcGISScene(BasemapStyle.ARCGIS_IMAGERY_STANDARD); // set the scene on the scene view sceneView.setArcGISScene(scene); // add base surface for elevation data Surface surface = new Surface(); String elevationServiceUrl = "https://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer"; surface.getElevationSources().add(new ArcGISTiledElevationSource(elevationServiceUrl)); // add an exaggeration factor to increase the 3D effect of the elevation. surface.setElevationExaggeration(2.5f); scene.setBaseSurface(surface); Point cameraLocation = new Point(-118.794, 33.909, 5330.0, SpatialReferences.getWgs84()); Camera camera = new Camera(cameraLocation, 355.0, 72.0, 0.0); sceneView.setViewpointCamera(camera);
-
In
start()
method, delete the code that creates anArcGISScene
by passing a basemap. In this tutorial, you will instead pass a portal item.App.javaUse dark colors for code blocks // create a scene view to display the scene and add it to the stack pane sceneView = new SceneView(); stackPane.getChildren().add(sceneView); ArcGISScene scene = new ArcGISScene(BasemapStyle.ARCGIS_IMAGERY_STANDARD); // set the scene on the scene view sceneView.setArcGISScene(scene);
Get the web scene item ID
You can use ArcGIS tools to create and view web scenes. Use the Scene Viewer to identify the web scene item ID. This item ID will be used later in the tutorial.
- Go to the LA Trails and Parks web scene in the Scene Viewer in ArcGIS Online. This web scene displays trails, trailheads and parks in the Santa Monica Mountains.
- Make a note of the item ID at the end of the browser's URL. The item ID should be 579f97b2f3b94d4a8e48a5f140a6639b
Display the web scene
You can display a web scene using the web scene's item ID. Create a scene from the web scene portal item, and display it in your app.
-
In the
start()
method, create a newPortal(java.lang.String,boolean)
referencing ArcGIS Online as theportal
parameter andUrl false
for thelogin
parameter.Required App.javaUse dark colors for code blocks Add line. // create a scene view to display the scene and add it to the stack pane sceneView = new SceneView(); stackPane.getChildren().add(sceneView); // create a scene from a web scene portal item and set it to the scene view Portal portal = new Portal("http://www.arcgis.com/", false); // set the scene on the scene view sceneView.setArcGISScene(scene);
-
Create a
PortalItem
for the web scene by passing theportal
and the web scene's item ID as parameters. -
Create an
ArcGISScene(com.esri.arcgisruntime.portal.PortalItem)
using theportal
as the constructor parameter.Item App.javaUse dark colors for code blocks Add line. Add line. // create a scene view to display the scene and add it to the stack pane sceneView = new SceneView(); stackPane.getChildren().add(sceneView); // create a scene from a web scene portal item and set it to the scene view Portal portal = new Portal("http://www.arcgis.com/", false); PortalItem portalItem = new PortalItem(portal, "579f97b2f3b94d4a8e48a5f140a6639b"); ArcGISScene scene = new ArcGISScene(portalItem); // set the scene on the scene view sceneView.setArcGISScene(scene);
-
Use the existing code to display the new
ArcGISScene(com.esri.arcgisruntime.portal.PortalItem)
on thescene
withView setArcGISScene()
.App.javaUse dark colors for code blocks Copy // create a scene view to display the scene and add it to the stack pane sceneView = new SceneView(); stackPane.getChildren().add(sceneView); // create a scene from a web scene portal item and set it to the scene view Portal portal = new Portal("http://www.arcgis.com/", false); PortalItem portalItem = new PortalItem(portal, "579f97b2f3b94d4a8e48a5f140a6639b"); ArcGISScene scene = new ArcGISScene(portalItem); // set the scene on the scene view sceneView.setArcGISScene(scene);
-
Run the app. Ensure to run the app as a Gradle task and not as an application in your IDE. In the Gradle tool window, under Tasks > application, double-click run.
Your app should display the scene that you viewed earlier in the Scene Viewer.
