GeoFencing to confirm location

Hey all, so I'm looking to deploy a survey which will see the same
locations being surveyed several times over the course of the study. A
baseline study will collect the location data for all the survey sites.

What I'd like is to be able to have a question which collects the gps
coordinate of the device at the time of the survey and confirms that it is
within a given range, say 100m of the gps coordinate which was collected in
the baseline study.

Has anyone come across a widget for doing this?

Cheers, David

David,

No such widget exists, but it's a long standing feature request.
https://code.google.com/p/opendatakit/issues/detail?id=78. Perhaps
someone in the community can build it.

If you are looking for a hacky way to do it, you could probably use a
complex regex constraint to approximate what numerical ranges would be
100m away from your current location.
