I am attempting to get the distance units (ft, mm, km, etc.) from a layer in my .mxd and display it on a windows form. How can I do this? I can access the distance units of a map by using IMap.DistanceUnits, but I have had trouble accessing the distance units of an individual layer.</SPAN></BODY></HTML> Sun, 07 Apr 2013 22:33:09 GMT ConorBarber1 2013-04-07T22:33:09Z [C#] Distance Units of a Layer https://community.esri.com/t5/arcobjects-sdk-questions/c-distance-units-of-a-layer/m-p/89515#M2358 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I am developing an ArcGIS desktop addin.

The solution they provided is to use IProjectedCoordinateSystem.CoordinateUnit. I was working with an ILayer, which uses ILayer.AreaOfInterest.SpatialReference. IProjectedCoordinateSystem inherits from SpatialReference, and can be accessed through casting:</SPAN><BR /><BR /><PRE class="plain" name="code"> ESRI.ArcGIS.Geometry.IProjectedCoordinateSystem lyrCoordSystem = (IProjectedCoordinateSystem)pLayer.AreaOfInterest.SpatialReference;&nbsp; lblSpatialReference.Text = lyrCoordSystem.CoordinateUnit.Name;&nbsp; </PRE><DIV style="display:none;"> </DIV></BODY></HTML> Mon, 08 Apr 2013 02:57:06 GMT https://community.esri.com/t5/arcobjects-sdk-questions/c-distance-units-of-a-layer/m-p/89516#M2359 ConorBarber1 2013-04-08T02:57:06Z
