arcgis-layers

You can add and configure ArcGIS map layers by creating FeatureLayer, TileLayer, or GeoJSONLayer instances from URLs or portal items, then setting properties like popupTemplate, renderer, and definitionExpression before adding them to a MapView or SceneView.

Yes, ArcGIS FeatureLayers support both client-side and server-side queries, allowing you to execute spatial queries, attribute queries, and extent calculations to drive map interactions and data visualizations within your application.

Yes, the approach supports both 2D MapView and 3D SceneView, allowing you to add, manage, and query layer types such as FeatureLayer, TileLayer, GeoJSONLayer, and GraphicsLayer across different dimensional views.

Layer management in ArcGIS Maps SDK is handled by adding, removing, reordering, and toggling the visibility of layers within the MapView or SceneView, which controls how overlapping data is displayed and interacted with.

You can load GeoJSON data by creating a GeoJSONLayer, which integrates local or remote GeoJSON sources into the ArcGIS map, allowing you to apply custom renderers, popups, and filters like other layer types.

Client-side queries on ArcGIS layers depend on the loaded feature data and its geometry, meaning complex spatial queries or large datasets may require server-side processing via the FeatureLayer URL to avoid performance issues.
