How to get elevation / Z value using map view object

TrilokChouhan — Thu, 29 Apr 2021 05:26:01 GMT

Our team is working on Run Time SDK to develop Mobile application for field survey. We have a requirement of elevation / Z value, we are using ArcGIS online basemaps in ESRI Map View for android.

Is there any way to get the elevation / Z value using map view object. Please suggest.

If you want to get elevation from screen coordinate in 3D using sceneview, you can look into the following sample.
https://github.com/Esri/arcgis-runtime-samples-android/tree/main/java/get-elevation-at-point

However if you looking to get elevation on a 2D MapView. Then you can add an elevation service like below provided one as a RasterLayer and perform mapView.identifyLayerAsync on that layer to get elevation. Note that the elevation service requires an ArcGIS Online organizational subscription or an ArcGIS Developer account

https://elevation.arcgis.com/arcgis/rest/services/WorldElevation/Terrain/ImageServer

RasterLayer rasterLayer = new RasterLayer(new ImageServiceRaster("ServiceURl"));

@RamaChintapalli, thank you for your help.

Out team are trying to get elevation on a 2D MapView also (not via 3D using scene view which works fine but consumes extra RAM and leads to overhead).

But loading of image service raster

val imageServiceRaster = ImageServiceRaster("https://elevation.arcgis.com/arcgis/rest/services/WorldElevation/Terrain/ImageServer")

always fails with the following error:

com.esri.arcgisruntime.ArcGISRuntimeException: Internal error.: Failed to read configuration data

Platform: Android

Version: 100.15.0

Are any suggestions/tips what can be the issue root cause?
