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.

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.
