Attribute Rule: Latitude and Longitude

Anonymous User

I'm trying to write an attribute rule that would write that writes the Latitude coordinates to a field.  However, the feature class I'm writing the rule on is projected in State Plane (Florida) in feet.  

I have found some examples of Attribute Rules that can take data in UTM(meters) and "translates" that into Lat/Long.  But that won't help here.

I need some concrete direction on 1) if this is even possible in Attribute Rules and 2) if so, what would that expression look like?

Hi @Anonymous User  and @DanPatterson ,

Unfortunately, Arcade does not yet provide the possibility to project a geometry to a different coordinate system. There are some examples that allow calculating the corresponding latitude and longitude coordinates when you have the standard Web Mercator Auxiliary Sphere as input coordinate system. 

The case mentioned above uses a mathematical formula to calculate the corresponding WGS 1984 coordinates. In case you have the formula you can implement it in Arcade. However, this might be complex and sometimes not very precise.
