Update raster width/height with pro sdk

Anonymous User — Tue, 06 Feb 2024 02:37:03 GMT

Hi Gurus,

Refer to this

After managed to create raster dataset, tried and change the raster size and update the extent and it does not update my raster properties.

SetExtent, SetWidth, SetHeight methods are used.

May I know what went wrong?

Below is my code snippet.

  string ExportTifFile = FileName + ".tif";
                    var parameters = Geoprocessing.MakeValueArray(
                         this.InputModel.DestinationPath, // Output path
                        ExportTifFile, // Raster name : make it as tif file
                         rasterInfo.CellSize.ToString(), // Cellsize
                         this.InputModel.PixelType, // pixel type
                         this._lastSelectedSR, // Spatial reference,
                         1); // Bands count

                    //IReadOnlyList<KeyValuePair<string, string>> environments = Geoprocessing.MakeEnvironmentArray(extent: pEnvelope);
                    var gpResult = Geoprocessing.ExecuteToolAsync("CreateRasterDataset_management", parameters, null,
                                        CancelableProgressor.None, GPExecuteToolFlags.GPThread);
                    gpResult.Wait();
                    IGPResult ProcessingResult =  gpResult.Result;
                    if (ProcessingResult.IsFailed)
                    {
                       foreach(IGPMessage message in ProcessingResult.Messages)
                        {
                            ConversionToolModule.Current.ModuleLogManager.LogError("Error on create raster dataset tool calling");
                            ConversionToolModule.Current.ModuleLogManager.LogError($"{{Error Code: {message.ErrorCode}, Text :  {message.Text} }}");
                        }
                        Geoprocessing.ShowMessageBox(ProcessingResult.Messages, "Raster creation error", GPMessageBoxStyle.Error);
                    }
//Try and update 
await QueuedTask.Run(() =>
                    {
                        FileSystemConnectionPath connectionPath = new FileSystemConnectionPath(new System.Uri(this.InputModel.DestinationPath), FileSystemDatastoreType.Raster);
                        FileSystemDatastore datastore = new FileSystemDatastore(connectionPath);

                        RasterDataset tmpFileRasterDataset = datastore.OpenDataset<RasterDataset>(ExportTifFile);
                                                
                        ArcGIS.Core.Data.Raster.Raster tmpRaster = tmpFileRasterDataset.CreateDefaultRaster();
                        if (tmpRaster.CanEdit())
                        {                          
                            Envelope RasterExtent = EnvelopeBuilder.CreateEnvelope((double)rasterInfo.MinX, (double)rasterInfo.MinY, (double)rasterInfo.MaxX, (double)rasterInfo.MaxX, this._lastSelectedSR);
                            tmpRaster.SetExtent(RasterExtent);
                            tmpRaster.SetWidth(rasterInfo.RasterColumnCount);
                            tmpRaster.SetHeight(rasterInfo.RasterRowCount);

                          
                            tmpRaster.Refresh();

                                                    }
                    }, ps.Progressor);

Hi Than,

I think you need to save your raster to get updated properties. Look at this link:

https://community.esri.com/thread/213505-raster-setwidth-not-working

Re: Update raster width/height with pro sdk

Thank Gintautas Kmieliauskas

That seems to be working now but it introduce another issue . The new set of saved raster dataset create dam different cell size of Y value.

Yep it save extent, width, height but it changes the cell size.

Hi Than,

What type is your rasterInfo.CellSize variable? Try to set constant value first (5,10 or 50). And you don't need to convert MakeValueArray arguments to string. They are all object type. MakeValueArray checks argument types itself and converts how it needs.

After MakeValueArray you can check parameters variable with debugger watch and see what value for cell size was defined.

Hi Gintautas,

Look like I confuse you.

Below is the full code snippet I used, the Raster Cellsize is good, when I used with Geoprocessing, after I called saved as method to save new set of raster data, it changed the cell size.

I attached the raster file before saveas and after save as function call.

string ExportTifFile = SourceFileName + ".tif";
                    string ExportFullTifFile = SourceFileName + "FullData.tif";
                    string tempFolderPath = Path.Combine(this.XYZInputModel.DestinationPath, "temp");

                    Directory.CreateDirectory(tempFolderPath);
                    //string ExportTifFile = SourceFileName;
                    var parameters = Geoprocessing.MakeValueArray(
                         tempFolderPath, // Output path
                        ExportTifFile, // Raster name : make it as tif file
                         rasterInfo.CellSize.ToString(), // Cellsize
                         this.XYZInputModel.PixelType, // pixel type
                         this._lastSelectedSR, // Spatial reference,
                         1, "", SourceFileName,
                         "128 128", "NONE", ""
                         ); // Bands count

                    //IReadOnlyList<KeyValuePair<string, string>> environments = Geoprocessing.MakeEnvironmentArray(extent: pEnvelope);
                    var gpResult = Geoprocessing.ExecuteToolAsync("CreateRasterDataset_management", parameters, null,
                                        CancelableProgressor.None, GPExecuteToolFlags.GPThread);
                    gpResult.Wait();
                    IGPResult ProcessingResult = gpResult.Result;
                    if (ProcessingResult.IsFailed)
                    {

                        }
                        Geoprocessing.ShowMessageBox(ProcessingResult.Messages, "Raster creation error", GPMessageBoxStyle.Error);

Hi Than,

Try to add line of code before calling SaveAs:

rasterStorageDef.SetCellSize(rasterInfo.CellSize, rasterInfo.CellSize);

Thank Gintautas,

But no hope, still changing the cell size y.

Re: Update raster width/height with pro sdk

Prashant_MukeshMangtani — Sun, 12 Dec 2021 09:38:20 GMT

Than,

In your code above when you create the extent envelope, you are setting MaxX instead of MaxY. Bolded below.

Envelope RasterExtent = 
EnvelopeBuilder.CreateEnvelope((double)rasterInfo.MinX, (double)rasterInfo.MinY, (double)rasterInfo.MaxX, (double)rasterInfo.MaxX, this._lastSelectedSR);

Thank Prashant Mukesh Mangtani‌,

That right, I did typo error.

It solve the cell size issue .

Best Regards,
