Hi,
In a polygon shapefile in geographic WGS84, I am trying to get the geodesic area in square kilometers using new Python fonctionalities with the Calculate Field, as explained in ArcGIS Ressource, in the Geometry unit conversions section:
http://resources.arcgis.com/en/help/...0000004s000000
However, when trying !shape.area@squarekilometers! in the code block, set on Python, it calculates the area in decimal degree, just like if I had typed !shape.area!
On the other hand, when typing !shape.length@kilometers! with a polyine shapefile in WGS84, it does calculates the geodesic distances in kilometers.
Why does it work with length but not area?
Cheers
