Hey all, We have a number of widgets built with 4.x in Typescript and end to end testing for testing these components as part of a web application but I'm struggling to figure out how to load up the API and then the widgets for unit testing in a framework such as Chutzpah, Jasmine, or Comma. I'm thinking that surely ESRI has a preferred test framework that they use while developing the API, Widgets, and other components. Does anyone have experience setting this up and could you help point me in the right direction? Thanks! ... View more

Hey All, I am attempting to create a TIN from a Raster Dataset: private void Example(IRasterDataset rasterDataset, IGeometry aoi)         {             ITin tin = new TinClass();             ITinEdit tinEdit = (ITinEdit)tin;               tinEdit.InitNew(aoi.Envelope);             var raster = rasterDataset.CreateDefaultRaster();             var rasterProps = (IRasterProps)raster;             var cellsize = rasterProps.MeanCellSize();             IPnt blocksize = new PntClass();             blocksize.SetCoords(Math.Floor(aoi.Envelope.Width / cellsize.X), Math.Floor(aoi.Envelope.Height / cellsize.Y));             //IRasterCursor rasterCursor = raster2.CreateCursorEx(blocksize);             var rasterCursor = ((IRaster2)raster).CreateCursorEx(blocksize);             var pixelBlock = rasterCursor.PixelBlock;             //Get the pixel blocks             IPnt tlc = new PntClass();             tlc.SetCoords(Math.Floor((aoi.Envelope.XMin - rasterProps.Extent.XMin) / cellsize.X), Math.Ceiling((rasterProps.Extent.YMax - aoi.Envelope.YMax) / cellsize.Y));             raster.Read(tlc, pixelBlock);             IPixelBlock3 pixelBlock3 = (IPixelBlock3)pixelBlock;             var pixels = (System.Array)pixelBlock3.get_PixelDataByRef(0);             object maxPoints = 3000000;             object toleranceAchieved = false;             object nodata = -9999.0;             try             {                 tinEdit.AddFromPixelBlock(aoi.Envelope.XMin + (cellsize.X / 2), aoi.Envelope.YMax - (cellsize.Y / 2), cellsize.X, cellsize.Y, nodata, pixelBlock, 1, ref maxPoints, out toleranceAchieved);             }             catch (Exception e)             {                 System.Diagnostics.Debug.WriteLine(e.Message);             }         } But I get a "Value does not fall within expected range" message on the exception. Any ideas? ... View more

Hello, I want to use the ILasSurface.InterpolateRaster method to get a DSM raster from the LasDataset but it only works if I pass in a RasterDataset that was created with LONG pixel type - what I really want is DOUBLE or FLOAT. However, the method throws a "Value does not fall within the expected range" argument exception if I pass it a RasterDataset that is DOUBLE or FLOAT. Is it even possible to get this result? Why would it be locked to LONG type? public IRasterDataset3 LasDatasetToDSM(ILasDataset lasDataset, IGeometry envelope)         {             esriSurfaceInterpolationType interpolationType = esriSurfaceInterpolationType.esriNaturalNeighborInterpolation             ILasSurface lasSurface = lasDataset.CreateDynamicSurface();                         ILasFilter lasFilter = (ILasFilter)new LasFilter();             lasFilter.AreaOfInterest = envelope;             ILongArray @returns = new LongArray();             @returns.Add(1);             lasFilter.Returns = @returns;             IRasterDataset rd = CreateTempRasterDataset(envelope.Envelope, LTK.Properties.Settings.Default.Cellsize, rstPixelType.PT_FLOAT);             try             {                 System.Diagnostics.Stopwatch sw = new System.Diagnostics.Stopwatch();                 sw.Start();                 lasSurface.InterpolateRaster(null, lasFilter, rd, -1, esriTinPointSelectionMethod.esriTinPointSelectionZmax, interpolationType, 1.0);                 sw.Stop();                 Logger.Log("DSM Created in " + sw.Elapsed.ToString());                 return rd;             }             catch (Exception e)             {                 Logger.Log(e.Message + " " + e.StackTrace, LogLevel.Error);             }             return null;         } ...

I have a portion of my application that creates temporary tiled raster datasets and then mosaics them back into a geodatabase raster dataset:   private void MosaicRasterIntoRasterDataset(IRaster raster, IRasterDataset rasterDataset)         {             IRasterDatasetEdit3 rdEdit = (IRasterDatasetEdit3)rasterDataset;             rdEdit.Mosaic(raster, 0.01);                         ((IRasterDataset3)rasterDataset).PrecalculateStats(0);             ((IRasterDataset3)rasterDataset).Refresh();         }   I'm not sure if PrecalculateStats or Refresh are even necessary here.   I release the reference to rasterDataset and the geodatabase workspace in the calling block before closing the thread.   Here's the issue: when I load this raster dataset into ArcMap, there are portions of the pyramids missing at different pyramid levels and sometimes the raster data doesn't display at full resolution either or recognize that there has been a change in extent. I say sometimes because it is truly hit or miss. Attempting to build pyrmids doesn't appear to do anything (takes 0-1 second) but restarting the application and deleting pyramids and then rebuilding them usually resolves these issues.   Am I missing something in the mosaic process to trigger the approporiate pyramids to be reconstructed? Does my thread need to stay open after I've made this call in order for the appropriate actions to happen in the GDB? Is this a bug in ESRI software (I've seen similar posts that make me think it might be but aren't definitive on this).   Note that I'm developing at Basic so Mosaic Dataset isn't an option here. ...
