Hello I want to add a local Wmtslayer to my project use this code，and got error message,Program crashes. But the same service is normal in arcgis map. I don’t know what the problem is. this is server xml [Server Wmts.xml](https://community.thinkgeo.com/uploads/default/original/3X/4/f/4f9903fa433bbd6d94395dfc1f4bebc9fec59611.xml) (11.1 KB) ``` map.MapUnit = GeographyUnit.Meter; // map.CurrentExtent = new RectangleShape(1254901.87822449, 6785639.16296541, 1734313.72055747, 6441979.14333386); // map.CurrentExtent = new RectangleShape(-80, 60, 80, -60); ThinkGeo.MapSuite.Layers.WmtsLayer wmtsLayer = new ThinkGeo.MapSuite.Layers.WmtsLayer(); wmtsLayer.DrawingExceptionMode = DrawingExceptionMode.DrawException; wmtsLayer.WmtsSeverEncodingType = ThinkGeo.MapSuite.Layers.WmtsSeverEncodingType.Kvp; wmtsLayer.ServerUris.Add(new Uri("http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS?")); wmtsLayer.ActiveLayerName = "GoogleEarthSatelliteMap"; wmtsLayer.ActiveStyleName = "default"; wmtsLayer.TileMatrixSetName = "AZMap_GoogleEarthSatelliteMap"; wmtsLayer.OutputFormat = "image/jpg"; wmtsLayer.SendingWebRequest += WmtsLayer_SendingWebRequest; wmtsLayer.Open(); LayerOverlay layerOverlay = new LayerOverlay(); layerOverlay.Layers.Add(wmtsLayer); map.Overlays.Add(layerOverlay); map.CurrentExtent = layerOverlay.GetBoundingBox(); map.Refresh(); ``` private void WmtsLayer\_SendingWebRequest(object sender, SendingWebRequestEventArgs e) { System.Diagnostics.Debug.WriteLine(e.WebRequest.RequestUri.ToString()); } show log: [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=3&TileCol=11 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=4&TileCol=15 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=4&TileCol=11 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=3&TileCol=12 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=3&TileCol=13 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=4&TileCol=12 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=3&TileCol=14 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=4&TileCol=13 [http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS](http://localhost:9009/arctiler/ogc/services/GoogleEarthSatelliteMap/WMTS)??service=WMTS&request=GetTile&version=1.0.0&layer=GoogleEarthSatelliteMap&style=default&format=image/jpg&TileMatrixSet=AZMap\_GoogleEarthSatelliteMap&TileMatrix=AZMap\_GoogleEarthSatelliteMap:0&TileRow=4&TileCol=1 ![](https://community.thinkgeo.com/uploads/default/original/3X/7/0/7088ed541c16228dce642b7fb45e0e8bf6a0f0b5.jpg)4 ---

Hi Zhangming, I guess the problem is parse capability met problem. The problem is we cannot test it because it’s a local WMTS server, please open the test service so we can debug to see where is the problem. Regards, Ethan ---

Try this one: [http://t0.tianditu.com/cia\_w/wmts?service=WMTS&version=1.0.0&request=GetCapabilities](http://t0.tianditu.com/cia_w/wmts?service=WMTS&version=1.0.0&request=GetCapabilities) ---

// ThinkGeo.MapSuite.Wpf.WmtsLayer private Collection MakeTileValidInCapabilities(Collection cells, TileMatrix tileMatrix) { Collection collection = new Collection(); if (this.wmtsServerLayers[0].2kI=.Count != 0) { foreach (uUI= current in this.wmtsServerLayers[0].2kI=) { if (tileMatrix.Id == current.jxQ=) { foreach (TileMatrixCell current2 in cells) { if (double.Parse(current2.Column.ToString(CultureInfo.InvariantCulture)) \>= current.w0I= && double.Parse(current2.Column.ToString(CultureInfo.InvariantCulture)) \<= current.xUI= && double.Parse(current2.Row.ToString(CultureInfo.InvariantCulture)) \>= current.v0I= && double.Parse(current2.Row.ToString(CultureInfo.InvariantCulture)) \<= current.wUI=) { collection.Add(current2); } } } } return collection; } return cells; } You guys should check the source code of WmtsLayer,especially MakeTileValidInCapabilities method.Why wmtsServerLayers[0] ? I believe you guys should have a lot of bug to fix. ---

Please confirm that WmtsLayer is ok after enable tile cache.Thank you. Sorry for my poor english. ---

Hi karl\_barkmann, As below is the sample about your server: ``` map.MapUnit = GeographyUnit.Meter; LayerOverlay layerOverlay = new LayerOverlay(); WmtsLayer wmtsLayer = new WmtsLayer(); wmtsLayer.SendingWebRequest += WmtsLayer_SendingWebRequest; wmtsLayer.ServerUris.Add(new Uri("https://t0.tianditu.com/cia_w/wmts")); wmtsLayer.DrawingExceptionMode = DrawingExceptionMode.DrawException; wmtsLayer.WmtsSeverEncodingType = ThinkGeo.MapSuite.Layers.WmtsSeverEncodingType.Kvp; wmtsLayer.Open(); wmtsLayer.ActiveLayerName = "cia"; wmtsLayer.ActiveStyleName = "default"; wmtsLayer.TileMatrixSetName = "w"; wmtsLayer.OutputFormat = "image/png"; layerOverlay.Layers.Add(wmtsLayer); wmtsLayer.Open(); map.CurrentExtent = new RectangleShape(-20037508.3427892, 20037508.3427892, 20037508.3427892, -20037508.3427892); map.Overlays.Add(layerOverlay); map.Refresh(); ``` The problem is, when it works the tile request url looks is not suitable the server, please find a valid tile request url and you can adjust the parameters to make it works. The currently url is for example: [https://t0.tianditu.com/cia\_w/wmts?service=WMTS&request=GetTile&version=1.0.0&layer=cia&style=default&format=image/png&TileMatrixSet=w&TileMatrix=w:0&TileRow=0&TileCol=1](https://t0.tianditu.com/cia_w/wmts?service=WMTS&request=GetTile&version=1.0.0&layer=cia&style=default&format=image/png&TileMatrixSet=w&TileMatrix=w:0&TileRow=0&TileCol=1) Regards, Ethan
