I am quite new to use REST API and trying to add point feature to my feature service right now.
I successfully added features but locations were very different from where I expected.
My data has only geometry in latitude and longitude, so I suppose what I need to do is transform lat, lon values to web mercator projection before adding data.
My question is that;
1) Can I specify spatial reference in add feature operation?
2) If I cannot specify the spatial reference in the operation, how can I transform lot & lon to web mercator coordinate values via REST API before add data?
If this kind of question was solved before, please suggest URL for the thread.
