How add correct coordinates to map in wgs 1984?

Radzhabad — Sat, 17 Apr 2021 06:58:55 GMT

xy = (47.550976, 42.963041)

array = arcpy.Array()
with arcpy.da.InsertCursor(schetchiki_path,['SHAPE@XY', 'Name']) as c:
    c.insertRow([xy,name])

That must be a partial script because whatever you are trying to do might just add a value to the Shape field but it won't do anything for the fields you have shown in your example

See in the help for python examples: Write geometries.

Or (MUCH easier!) create a table with your xy values in it and use the XY Table To Point, or Make XY Event Layer tools to create your points.

I changed to using Arcade so that the lat/longs are always up to date. No one remembers to change them when they move a point. Works great in a web map or ArcPro.

Another option if using SDE is Attribute Rules so that they autoupdate.

WGS 84 in Arcade

CurrentLat
var originShift = 2.0 * PI * 6378137.0 / 2.0;
var lon = (Geometry($feature).x / originShift) * 180.0;
var lat = (Geometry($feature).y / originShift) * 180.0;

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

return lat;

CurrentLong
var originShift = 2.0 * PI * 6378137.0 / 2.0;
var lon = (Geometry($feature).x / originShift) * 180.0;
var lat = (Geometry($feature).y / originShift) * 180.0;

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

return lon;

Make sure to config the popup to show 8 decimals.

Hope that helps. I know not what you asked but it may work for you.
