Is it possible to calculate points XY coordinates in Decimal Degrees in model or script when a feature class is in projected coordinate system?
It's easy when a FC is in geographic coordinate system:
- using Add XY Coordinates tool or
- using Python expression eg.
I've found that area and length properties of geometry field can be modified with geometry unit conversion keyword. For linear units of measue one can use @DECIMALDEGREES.
!shape.extent.XMax@decimaldegrees! doesn't work as XMax is not a length.
In Calculate Geometry function (accessed from right-click) there's a possibility to choose Decimal Degrees output type even for projected feature class.
This should be easy in ArcGIS Python, isn't it?
Here's a code snippet based on iRfAn's solution:
import arcpy, os projectedFC = r"C:\tmp\test.gdb\points01_Projected" prjFile = os.path.join(arcpy.GetInstallInfo()["InstallDir"], r"Coordinate Systems\Geographic Coordinate Systems\World\WGS 1984.prj") spatialRef = arcpy.SpatialReference(prjFile) updCursor = arcpy.UpdateCursor(projectedFC,"", spatialRef) for row in updCursor: pnt = row.Shape.getPart(0) row.X = pnt.X row.Y = pnt.Y updCursor.updateRow(row) del updCursor, row
