Is it possible to get Survey123 to autopopulate (pull) geopoint data in a British XY format into a field?
I interpret that you want to take the Latitude/Longitude values from a geopoint question and calculate the corresponding XY values in a particular OS National Grid Reference. If that is the case, I would say the answer is no. The expressions you can use in XLSForms are not meant to support this type of calculations. I would recommend that you do the conversion in ArcGIS Desktop as a post-processing step.
TheAdd more coordinate entry formats for Survey123 idea may somewhat fit your needs (admittedly, two different things). Have a look at the idea in case that you want to vote for it or add some comments for consideration.
Thanks a lot!
Thanks, I did have a feeling that it is not yet possible to do so. The post processing step will would fine in this case.
