It is still possible to run the ArcGIS Diagrammer, even with ArcGIS 10.6.: Just install the Diagrammer from the following link: https://www.arcgis.com/home/item.html?id=51b6066bfd024962999f6903682d8978 Navigate to C:\Program Files (x86)\ArcGIS\Desktop10.6\bin and locate the ArcMap.exe.config file. Open it in Notepad or Notepad++ and copy the whole content. Navigate to C:\Program Files (x86)\ArcGIS Diagrammer\BIN and locate the ESRI.ArcGIS.ArcDiagrammer.exe.config file open it, and paste the content of the ArcMap.exe.config file. Save it. You probably need administrative privileges to do so. Go to C:\Windows\Microsoft.NET\assembly\GAC_MSIL\ESRI.ArcGIS.Geodatabase\v4.0_10.6.0.0__8fc3cc631e44ad86 and copy ESRI.ArcGIS.Geodatabase.dll and paste to C:\Program Files (x86)\ArcGIS Diagrammer\BIN. You probably need administrative privileges. Go to C:\Windows\Microsoft.NET\assembly\GAC_MSIL\ESRI.ArcGIS.System\v4.0_10.6.0.0__8fc3cc631e44ad86 and copy ESRI.ArcGIS.System.dll and paste to C:\Program Files (x86)\ArcGIS Diagrammer\BIN. You probably need administrative privileges. Voilà! Start C:\Program Files (x86)\ArcGIS Diagrammer\BIN\ESRI.ArcGIS.ArcDiagrammer.exe. Warning! This is not a new version, still the old Diagrammer. Some new geoadatbase features, like editor tracking and new annotations from Pro are not supported. You can export the created xml and import into a new geodatabase, however you won’t be able to open a newly exported workspace document xml in the Diagrammer. So now it is a one way tool. The Diagrammer uses workspace document xml version 9.2, the 2.3 Pro uses 10.7. so there is no way going back. But it is still OK for me. The paths may vary depending on your installations and ArcGIS version. The solution is not working with ArcGIS Pro, you need to have an ArcGIS for Desktop ArcMap installed. This solution is not perfect just a workaround–use at your own risk.   Ákos Halmai ... View more

I can't give a working Java code, but in C# it looks like this (below). However, it won't create a file, the result is a folder. It is a totally empty GDB. [MethodImpl(MethodImplOptions.AggressiveInlining)] private static Geodatabase CreateFileGDB(string GDBPath) { // Test the argument: const string NameOfGDBPath = nameof(GDBPath); if (string.IsNullOrWhiteSpace(GDBPath)) throw new ArgumentNullException(NameOfGDBPath, "Geodatabase path cannot be null; empty or whitespace-only string."); DirectoryInfo directoryInfo = new DirectoryInfo(GDBPath); if (!directoryInfo.Parent.Exists) throw new DirectoryNotFoundException("The parent directory (" + directoryInfo.Parent.FullName + ") was not found!"); if (directoryInfo.Exists) directoryInfo.Delete(true); //Create the GDB: return Geodatabase.Create(directoryInfo.FullName); } ...

Hi, The problem is in the SQL query: it seems, there is no planer/optimiser in FileGDBApi. To execute the original SQL ($"SELECT count(*) FROM TableName WHERE OBJECTID=1 or OBJECTID=2") takes 4466 ms on my table but to execute this one is only 16 ms on first run and 1 ms on second run: "SELECT Count(*) FROM Original WHERE OBJECTID IN (1, 2);" The full code: RowCollection rows = GDB.ExecuteSQL("SELECT Count(*) FROM Original WHERE OBJECTID IN (1, 2);"); foreach (Row row in rows) // Just to be generic. { int i = (int)row.GetDouble(0); } Ákos Halmai ...

Dear Kory, I can't miss the route identify function, so I tried to write my own. Is this code OK, or there is a better/shorter option? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using ArcGIS.Core.CIM; using ArcGIS.Core.Data; using ArcGIS.Core.Geometry; using ArcGIS.Desktop.Catalog; using ArcGIS.Desktop.Core; using ArcGIS.Desktop.Editing; using ArcGIS.Desktop.Extensions; using ArcGIS.Desktop.Framework; using ArcGIS.Desktop.Framework.Contracts; using ArcGIS.Desktop.Framework.Dialogs; using ArcGIS.Desktop.Framework.Threading.Tasks; using ArcGIS.Desktop.Mapping; namespace T2 { internal class MT2 : MapTool { public MT2() { IsSketchTool = true; SketchType = SketchGeometryType.Point; SketchOutputMode = SketchOutputMode.Map; } protected override Task OnToolActivateAsync(bool active) => base.OnToolActivateAsync(active); protected override async Task<bool> OnSketchCompleteAsync(Geometry geometry) { if (geometry != null && !geometry.IsEmpty && ActiveMapView != null) { string RetString = await QueuedTask.Run(() => { IReadOnlyList<Layer> LayerList = ActiveMapView.Map.GetLayersAsFlattenedList(); int LayerCount = LayerList.Count; if (LayerCount <= 0) return "There is no layer on this map/scene!"; List<FeatureLayer> M_Layers = new List<FeatureLayer>(LayerCount); for (int i = 0; i < LayerCount; i++) { FeatureLayer featureLayer = (FeatureLayer)LayerList; if (featureLayer != null) using (FeatureClassDefinition featureClassDefinition = featureLayer.GetFeatureClass().GetDefinition()) if (featureClassDefinition.HasM()) M_Layers.Add(featureLayer); } if (M_Layers.Count <= 0) return "There is no M-aware layer on this map/scene!"; IGeometryEngine engine = GeometryEngine.Instance; MapPoint mapPoint = (MapPoint)geometry; StringBuilder stringBuilder = new StringBuilder(); var LayerDictionary = ActiveMapView.GetFeatures(geometry); foreach (var item in M_Layers) if (LayerDictionary.ContainsKey(item)) { stringBuilder.AppendLine(item.Name + ":"); using (RowCursor cursor = item.Search(new QueryFilter() { ObjectIDs = LayerDictionary[item].AsReadOnly() })) while (cursor.MoveNext()) using (Feature feature = (Feature)cursor.Current) stringBuilder.AppendLine("\t" + engine.NearestPoint(feature.GetShape(), mapPoint).Point.M.ToString("0.####")); } return stringBuilder.ToString(); }); MessageBox.Show(RetString,"Hit results"); } return true; } } } ...

I posted it as an idea, but from different point of view it could be a bug. Thanks!

Let’s imagine a triangle in a Cartesian (projected-) coordinate system, with the following coordinates: A(1, 1, 2), B(3, 1, 2) and C(1.5, 3, 2) where the fist number of the coordinate is measured in metes, along the X axis, the second number is measured along the Y axis, and the third one measured along the Z axis. The order of the coordinates is counter clockwise. Actually, the Z value is constantly 2 for all the points. How can we calculate the centroid of this polygon (triangle)? CentroidX= (AX+BX+CX)/3; CentroidY=(AY+BY+CY)/3; CentroidZ=(AZ+BZ+CZ)/3. The results are the following: Centroid(1.833333, 1.666666, 2). This coordinate point is inside, on the plane of the triangle. If I use the Feature to Point against this triangle the result is Centroid(1.833333, 1.666666, NaN), where the “NaN” means “Not a Number” (it represented as 0 on the user interface). The result in the XY plane is correct, but the Z coordinate is missing (or zeroed). In this case the output feature class is technically z aware, but there is no Z information inside. In arcpy the Polygon.centroid() function calculates the correct Centroid(1.833333, 1.666666, 2) value. It would be beneficial if the results would be the same. I think the algorithm of the “Feature to Point” was written before the introduction of the idea of Z aware feature classes. ... View more
