Problems Adding Raster to GeoPackage

I'm trying to create a GeoPackage that contains a raster image using .NET and C#. I was able to do something similar in Python but can't seem to get it to work in C#. Here's the simplified code:

private Task BuildExport () { string output = @"C:\Data\GeoPackage.gpkg"; return QueuedTask.Run(() => { if (SelectedMapFeatures == null) return; try { var parameters = Geoprocessing.MakeValueArray(output, "GEOPACKAGE"); var result = Geoprocessing.ExecuteToolAsync("management.CreateSQLiteDatabase", parameters, null, null, null, GPExecuteToolFlags.None); foreach (var map in SelectedMapFeatures) { foreach (var feature in map.Value) { parameters = Geoprocessing.MakeValueArray(feature.Raster, output, feature.Name, "Tiled", null); result = Geoprocessing.ExecuteToolAsync("conversion.AddRasterToGeoPackage", parameters, null, null, null, GPExecuteToolFlags.None); } } } catch (Exception ex) { Debug.WriteLine(ex.ToString(), Assembly.GetExecutingAssembly().FullName); } }); }

The GeoPackage is created just fine but adding the raster fails. An exception is thrown on line 18 of the MakeValueArray for the first parameter:

TAKInterface, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null: System.InvalidOperationException: convert unsupported type
at ArcGIS.Desktop.GeoProcessing.ObjectToValueConverter.to_string(CoreObjectsBase b, Object& oref)
at ArcGIS.Desktop.GeoProcessing.ObjectToValueConverter.ToString(Object o, Object& oref)
at ArcGIS.Desktop.Core.Geoprocessing.Geoprocessing.MakeValueArray(Object[] args)
at TAKInterface.TAKExporterDockPaneViewModel.<>c__DisplayClass26_0.<BuildExport>b__0() in C:\Users\...

The type for feature.Raster is RasterValue. I've tried using feature.Raster.GetRasterDataset() with the same error.

So, the question I have, is how do I get my raster into my GeoPackage?

Hi,

The first parameter of "conversion.AddRasterToGeoPackage" is RasterLayer. See documentation:

Add Raster to GeoPackage (Conversion)—ArcGIS Pro | Documentation

So you need to add raster to map and then pass result RasterLayer to geoprocessing.
