Lat/Long unit conversion with Arcade

ahkim

I am adding geometry fields using Arcade Geometry($feature).x and Geometry($feature).y. Since my target feature layer is in Web Mercator projection, my custom lat & long fields are displaying the values in meter. Is there a way to convert this to decimal degrees with arcade function?

Yes you can. If you use the function below you will be able to convert the Web Mercator Auxiliary Sphere coordinates into Lat and Long (WGS 1984):

In this case you have two functions: MetersToLatLon (lines 1 - 11) for converting web merc into lat lon, the CreateWazeURL function (lines 13 to 15) for creating a navigation URL based on lat and lon.

The actual code starts on line 17 where a list is created containing the lat and lon converted from the X and Y extracted from the geometry.

On line 18 the lat and lon values are passed to the CreateWazeURL function and the URL that is returned from the function is returned as result.

It would be great to have some increased functions added to arcade to include ToLatitude(geometry($feature).x) and ToLongitude(geometry($feature).y)

Please consider adding a kudo to this idea

RyanBohan

Thank you! I had a Rest endpoint with only x,y in the attributes.

Your arcade worked perfectly to be able to use google directions

var x = Geometry($feature).x

var y = Geometry($feature).y

// Converts XY point from Spherical Mercator EPSG:900913 to lat/lon in WGS84 Datum

// Fuente: http://www.maptiler.org/google-maps-coordinates-tile-bounds-projection/

var originShift = 2.0 * PI * 6378137.0 / 2.0;

var lon = (x / originShift) * 180.0;

var lat = (y / originShift) * 180.0;

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

//return [lat, lon];

var string = "https://www.google.com/maps/dir/?api=1&destination=" + lat + "," + lon + "&tavelmode=walking"

return string

TylerDeBruin

Is there an arcade code similar to this to show easting/westing?

Thank you Xander. Do you know where it would be possible to find a list of the projection engines supported and available in Arcade? I'm wondering if maybe MGRS may be in there instead...

XanderBakker

Unfortunately I don't. If you have access to the formula required I guess it would be possible to implement it in a similar way. I guess we have to wait until the projection engine is supported and available in Arcade to do this kind of transformation.

Anonymous User

Hi Xander, thank you for your post this is very useful!!

Also - I was wondering if you had some ideas on how we could run a similar conversion to get USNG coordinates instead?

Thanks again,

Alix
