Click on a 3D layer building to get building metadata from OSM

I am studying the ArcGis for Unity SDK for some time and have been tweaking the SampleArcGisRaycast component from the Unity SDK to various interesting things. Now I want to make a way to get Open Street Map Metadata by clicking on each building. For now, getting them to be written in Debug.Log would be enough.

I followed up on many documentation articles and ArcGis blogs about the subject, but I could not find a way to implement this. To be honest I don't even understand where I should start and the milestones of creating such a system. My starting point was this article> https://www.esri.com/arcgis-blog/products/arcgis-living-atlas/mapping/live-openstreetmap-data-in-arcgis/

At the moment, I managed to console log a value called `featureId` from the SampleArcGisRaycast component, --some kind of a value that is uniquely assigned to each building. Is there a way to request OSM building information from this `featureId` value?

here's the updated code I used to get the feature ID:

void Update(){ if (Input.GetKey(KeyCode.LeftShift) && Input.GetMouseButtonDown(0)) { RaycastHit hit; Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); if (Physics.Raycast(ray, out hit)) { var arcGISRaycastHit = arcGISMapComponent.GetArcGISRaycastHit(hit); var layer = arcGISRaycastHit.layer; var featureId = arcGISRaycastHit.featureId; DumpToConsole(arcGISRaycastHit.layer); DumpToConsole(arcGISRaycastHit); if (layer != null && featureId != -1) { popUp.SetActive(true); // featureText is an UI text featureText.text = featureId.ToString(); metadataText.text = JSONReader.getCity(featureId.ToString()); var geoPosition = arcGISMapComponent.EngineToGeographic(hit.point); var offsetPosition = new ArcGISPoint(geoPosition.X, geoPosition.Y, geoPosition.Z + 200, geoPosition.SpatialReference); var rotation = arcGISCamera.GetComponent<ArcGISLocationComponent>().Rotation; var location = canvas.GetComponent<ArcGISLocationComponent>(); location.Position = offsetPosition; location.Rotation = rotation; Debug.Log("Location == x: " + location.Position.X + "| y: " + location.Position.Y+"| z: " + location.Position.Z); Debug.Log("Location p == x: " + location.position.X + "| y: " + location.position.Y + "| z: " + location.position.Z); Debug.Log("GeoPosition == x: " + geoPosition.X + "| y: " + geoPosition.Y + "| z: " + geoPosition.Z); } else { popUp.SetActive(false); } } } #endif }

My other guess to get this working is to somehow get the coordinates of the building and then find a way to get the OSM metadata according to the coordinates. Or should I follow a different path?

which dataset are you using? Note that we don't currently support https://www.arcgis.com/home/item.html?id=ca0470dbbddb4db28bad74ed39949e25 but this is a highly requested service so it's high on our priority list.
