Interviewer modify GPS position

Is it possible to include a gps question that allows the user to move the geolocation to reference places that are difficult to access?

No, don’t do that. The idea of the GPS question is to capture the location of the interview (where the interviewer is).

For that use the geography question.

OK thank you very much.
On the same point when registering the GPS question, is there any way to show the map offline or view any of the maps previously loaded on the tablet?

What is the use story ?
