Detailed Description
A geo-element represents abstract geographic entities on a map. Classes that inherit from GeoElement provide concrete implementations such as graphics in a graphics overlay, features in a layer, and so on.
Each geographic entity can possess geometry, to describe the location and shape of the entity, and a set of attributes to provide information about the real-world entity it represents. For example, a feature in a feature layer, a graphic in a graphics overlay, and a raster cell in a raster layer are represented by the Feature, Graphic, and RasterCell classes. Each class inherits from GeoElement.
Operations that identify all of the layers in a map or scene, such as GeoView::identifyLayersAsync, can return a collection of IdentifyLayerResult objects. You can obtain the various types of GeoElement objects using IdentifyLayerResult::geoElements.
Relevant samples:
- Configure clusters: Add client side feature reduction on a point feature layer that is not pre-configured with clustering.
- Display clusters: Display a web map with a point feature layer that has feature reduction enabled to aggregate points into clusters.
- Identify raster cell: Get the cell value of a local raster at the tapped location and display the result in a callout.
- Line of sight (geoelement): Show a line of sight between two moving objects.
- Orbit the camera around an object: Fix the camera to point at and rotate around a target object.
- Scene layer selection: Identify features in a scene to select.
- Set up location-driven Geotriggers: Create a notification every time a given location data source has entered and/or exited a set of features or graphics.
- Viewshed (GeoElement): Analyze the viewshed for an object (GeoElement) in a scene.
