Why  doesn't  the annotation  and the map  match? There are two arcgis map services. The map service is http://mape.shanghai-map.net/ArcGIS/rest/services/SHMAP_D/MapServer. The annotation   service   is   http://mape.shanghai-map.net/ArcGIS/rest/services/SHMAP_DZJ/MapServer. The webgis which I use is openlayer3. new ol.layer.Tile({ source: new ol.source.TileArcGISRest({ url: "http://mape.shanghai-map.net/ArcGIS/rest/services/SHMAP_D/MapServer" }) }), new ol.layer.Tile({ source: new ol.source.TileArcGISRest({ url: "http://mape.shanghai-map.net/ArcGIS/rest/services/SHMAP_DZJ/MapServer" }) })   But  the  annotation   doesn't  match   the  map. 1、Does the annotation  has  to  import with  special method  in openlayer3?   Why  doesn't  the annotation  and the map  match?   I tried use  map tile of the two service, But I can't exactly calculate the Y value and I don't know the {z}/{y}/{x}? I  tried use a function of openlayer3 to  calculate the z\ y\x value, but I can't  calculate the Y value  very accurate. The code as below: var source = new ol.source.XYZ({ wrapX: false, // tileSize: 512, tilePixelRatio: 2, tileGrid: ol.tilegrid.createXYZ({}), tileUrlFunction: function (tileCoord) { const u = 'http://mape.shanghai-map.net/ArcGIS/rest/services/SHMAP_D/MapServer'; let z = tileCoord[0]; let x = tileCoord[1]; let y = -tileCoord[2] - 1; // let z = 'L' + (this.zeroPad(tileCoord[0], 2, 10)); // let x = 'C' + this.zeroPad(tileCoord[1], 8, 16); // let y = 'R' + this.zeroPad(-tileCoord[2] - 1, 8, 16); return u + '/tile/' + (z - 10) + '/' + (y - Math.pow(2, z - 2) + Math.pow(2, z - 😎 + 1) + '/' + x; } 2、Why should I have to  calculate the z\ y\x value?     Doesn't use  http://mape.shanghai-map.net/ArcGIS/rest/services/SHMAP_DZJ/MapServer/tile/{z}/{y}/{x}  directtly?  How can I calculate the y-value right? ...

The SQLServer DataBase is ok and the username and the password is right,why can't connect to SQLServer DataBase. The arcgis server is 10.4,the SQLServer is 2008 R2.When I connect to database,it will show message "Connection was attempted with an older version of SQL Server client communications sofeware that is not supported. I have installed SQLServer2008 R2,and use the "Microsoft SQL Server Management Studio" to connect database instance is ok.   The ArcGIS10.4 desktop  doesn't  contain  SQL Server client connect to  SQLServer2008 R2? If ture,which software I can download?   Where I can find it? Why the ArcGIS10.4 desktop can't  compatible with SQLServer2008 R2?  The 10.4 is so high. ... View more

Why  I  only can do  registration use  two points on AutoCAD file  every time ?    Seven points to determine the location of the map, isn't it? I chose 14 points to positioning,use  two points every time. From the first group to the seventh group.Each time  will generate a "WLD" file. What is "WLD" file about? Is it only the last two points is work?    The registration of the previous 6 group points  is not action? How  to  make  geographic  registration  is accurate on AutoCAD file use more than two points?     The question as below attachment picture. ... View more

When I import  annotation from AutoCAD to ArcGis10.4,the  annotation  is shown as points. Because  there  is  no check  'Label features in this layer' option? But where is this option,I can't find from 选中图层(Layers)-->右键“属性”(properties)-->点击"Labels"选项卡(Lables)，勾选"Label features in this layer" -->确定(Confirm) Whether arcmap in  arcgis10.4 compare with arcgis10.0,the option  is different?   Where is it  in  arcgis10.4 ,on the 'display panel' 'field  panel' or 'annotation panel'? How  can I make the annotation text of AutoCAD show on ArcGIs layer,not little point. ... View more

When I publish the webservice through Arc MAP 10.4.1 , the final stage of releasing service appeare 'the server is not ready for publishing.' The sample service of Arc Server 10.4.1 can be access. Restarting the Arc Server service, it still doesn't work. The Arc Server is authorized and was installed in the c drive of computer. Does the Arc Server 10.4.1 need to reinstall or to patch??? ...

Using with ArcCateLog tools convert the cad dwg file into shap file. Now we can know the longitude and latitude of ten points on the cad dwg file,how to set the coordinate of shap file? We should publish the shap file data as restful webservice. I use Arc MAP 10.4.1 and Arc Server 10.4.1. We can know the longitude and latitude of ten points on the cad dwg file,is that say we know about real coordinates? But,how we can get a real projection system use the ten points on the cad dwg file? Is there some examples to reference???? 1.The shp file which is converted from cad file. 2.The png file with ten points on which is printed from cad file.The longitude and latitude is signed by hand on the png with Photoshop. Can we use the map matching tools? Using png file to match shp file,is it feasible? Can I sign the longitude and latitude of ten points to dwg file directly??? Whether the shapefile will carry with the longitude and latitude when convert from dwg file??? Whether it need install plug-in for autoCAD in order to sign the longitude and latitude of ten points to dwg file directly. The I just have a cad dwg file and a txt text file. In the text file has recorded longitude and latitude of ten points which have signed on the dwg file. In a word ,the fundamental goal is set  longitude and latitude on shapefile with known ten geography points. ... View more
