Hello,

I have arcgis pro 2.7.2 and sde point feature class..using attribute rule for X and Y in decimal degrees (DD). I found two different scripts from geonet. Please see issues and screenshots below. Please advise. Thank you.

Script #1 one field type text and 100 characters ATTRUBUTE RULE. nothing happen. 

 

 

var polyx = text(centroid($feature).x);
var polyy = text(centroid($feature).y);

function metersToLatLon(mx, my) {

   var originShift = 2.0 * PI * 6378137.0 / 2.0;

   var lon = (mx / originShift) * 180.0;

   var lat = (my / originShift) * 180.0;

   lat = 180.0 / PI * (2.0 * Atan(Exp(lat * PI / 180.0)) - PI / 2.0);
return [lat, lon];

}

var latlon = "";
var result = "";
var latlon = metersToLatLon(polyx, polyy);

result = Round(latlon[0], 6) + ', ' + Round(latlon[1], 6);


return result;

 

 

 

Script # 2 TWO fields x and y. DOUBLE(38, 8). It is populated but not the correct DD number.

it displays 7.1233 and 4.1234 something. But it is supposed to be -80 and 25 something.

 

 

//Latitude

var y = Centroid($feature).y

var originShift = 2.0 * PI * 6378137.0 / 2.0;

var lat = (y / originShift) * 180.0;

lat = 180.0 / PI * (2.0 * Atan( Exp( lat * PI / 180.0)) - PI / 2.0);

return lat
//Longitude

var x = Centroid($feature).x

var originShift = 2.0 * PI * 6378137.0 / 2.0;

var lon = (x / originShift) * 180.0;

return lon

 

 

 

But then I tried to add calculate geometry tool and add geometry attribute tool manual. I got both same error.

Was there an actual fix for this? I get the Traceback issue as well, but my lines of code for py. are different. I figured if you had something then maybe I could look into it.
