Coordinate Conversion

DonnaDexter1

I have a need to get the X and Y coordinates  of a point in State Plane and WGS84 on the fly at the same time.  Meaning I need to populate two sets of X and Y fields - (on the fly) - one for State Plane and the other WGS84.

Does anyone have a solution for this?

I can have my data in State Plane then calculate the X,Y fields; then project to WGS84 and re-caculate x and y fields; but I need this to be done at the time of collection through a web app.

Any input would be greatly appreciated!

Which web app flavor are you planning to use.  That may make a difference on the answers you get (or more focuses anyway) and you options.  In any case you will probably need a custom app.

Look at ArcGIS for Developers | ArcGIS for Developers to see some of you options.

For the Web Appbuilder developer edition, check out my blog page Web AppBuilder Developer Edition - Customization Resource List​

Once you decide, it would be good to move your post to the proper space to get more direct/focussed responses.  see GeoNet Community Structure   and Moving Content​  for help on that.
