I know this is an old post, but i am trying to do this myself.  However, no matter what I do, the geotiff is not loading properly into a GIS app (ArcGIS Pro).  I know the modeltiepoint values are being written to the file, as i am able to read them back in with System.Drawing.Imaging.PropertyItem. Do you have any sample code that shows exactly what you did with the tiePoints (as you mention in your pseudo-code)?  Also, do you need to set a projection anywhere? I have seen and used the info here: http://geotiff.maptools.org/spec/geotiff2.6.html , but still no luck.  //Populate the modelTilePoint array // modelTilePoint[0] = someValue; //... ... View more

Thanks for your reply!  Could you explain a little further:  you mentioned  that "The capability of generating elevation profile from an existing file is currently supported in  ArcGIS Earth (the latest version 1.9).".  I just upgraded from 1.8 to 1.9 and can't seem to find this.  I can see how to generate an elevation profile from a drawn line, OR by using the interactive analysis (button looks like a cube), but i can't see how to import a line (either from KML or CSV) and THEN generate an elevation profile from it.  Thanks in advance. ...

OK, So i used the geoprocessing/viewshed example to come up with the code below.  It makes the call and receives a reply.  However, the geometry that gets returned is only a polyline, and not a polylineZ (containing z values of the ground).  Does anyone have an idea why it does not appear to be working?  I thought it was something in the fieldlist but i tried multiple things there (including none), but nothing seemed to change the returned result.              var myProfileTask = await GeoprocessingTask.CreateAsync(new Uri(_viewshedUrl));             List<Field> fieldList = new List<Field>();             fieldList.Add(new Field(FieldType.OID, "ObjectID", "ObjectID", 10));             fieldList.Add(new Field(FieldType.Float64, "Shape_Length", "Shape_Length", 10));             var myInputFeatures = new FeatureCollectionTable(new List<Field>(), GeometryType.Polyline, SpatialReferences.WebMercator);             Feature myInputFeature = myInputFeatures.CreateFeature();             _selectedGraphics[0].Attributes.Add("ObjectID", 1);             _selectedGraphics[0].Attributes.Add("Shape_Length", GeometryEngine.LengthGeodetic(_selectedGraphics[0].Geometry,LinearUnits.Meters,GeodeticCurveType.Geodesic));             myInputFeature.Geometry = _selectedGraphics[0].Geometry;             await myInputFeatures.AddFeatureAsync(myInputFeature);             GeoprocessingParameters myProfileParameters =                 new GeoprocessingParameters(GeoprocessingExecutionType.SynchronousExecute);             myProfileParameters.OutputSpatialReference = SpatialReferences.WebMercator; ;             myProfileParameters.Inputs.Add("InputLineFeatures", new GeoprocessingFeatures(myInputFeatures));             var myViewshedJob = myProfileTask.CreateJob(myProfileParameters);             try             {                 GeoprocessingResult myAnalysisResult = await myViewshedJob.GetResultAsync();                 GeoprocessingFeatures myProfileResultFeatures = myAnalysisResult.Outputs["OutputProfile"] as GeoprocessingFeatures;                 // Add all the results as a graphics to the map                 IFeatureSet myViewshedAreas = myProfileResultFeatures.Features;                 foreach (var myFeature in myViewshedAreas)                 {                     _resultOverlay.Graphics.Add(new Graphic(myFeature.Geometry));                 }             }             catch (Exception ex)             {                 // Display an error message if there is a problem                 //if (myViewshedJob.Status == JobStatus.Failed && myViewshedJob.Error != null)                 //    _userViewModel.UserMessage="Executing geoprocessing failed. " + myViewshedJob.Error.Message, "Geoprocessing error";                 //else                 //    MessageBox.Show("An error occurred. " + ex.ToString(), "Sample error");             }             finally             {                 // Indicate that the geoprocessing is not running                 //SetBusy(false);             } ...

Thanks Morton.  After my post i realized that the Pro and Runtime backgrounds defaulted differently (white vs grey with grid). I did not realize i could change that background and had overlooked that option to do so.  Thanks!  ... View more

Has anyone had this issue and been able to resolve it?  I get this error on any dataset I run (esri sample datasets, pix4d sample datasets, my own datasets).  I get this error everytime I try to generate a dsm or dtm and have tried changing multiple settings but still get the same error.   ...
