I got it, the data have to be projected to mercator, if not, it is not visualised. I don't know if it is an error or a prerequest for the localserver

Just to add some details that may help finding a solution :

When I look to the Image layer parameters, I find this in the "Spatial reference" field : SpatialReference = 'localServiceLayer.SpatialReference' threw an exception of type 'System.InvalidOperationException'

If I use mpkx file (resulted from arcgis pro), I got : Failed to create service delme MapServer. Service failed to initialize: IObjectConstruct::Construct (MapServer) hr=0x80043000 (ErrorInfo did not include a description)

Hi,

The ArcGISMapImageLayer should request a map image from the LocalMapServices in the spatial reference of the MapView so this might be a bug (although we do always recommend that your data should share a common spatial reference, to avoid the overhead of reprojecting on the fly).

What data formats/types are in your MPK and what other layers are in your Map (both basemap and operational)?

Cheers

Mike

Hi,

thanks for your answer. In fact, I can understand that a .mpk file has to use the same spatial reference as the MapView, but I only expected to get some error message.

In my MapView, I has one elevation layer of WGS84(4326) from an arcgis server + graphics layer + openstreetmap layer.

In the mpk, I had WGS84(4326) layer. I reproject it to epsg:3857 to be able to visualise it.
