I would like to add some fields that are invisible to the user. Specifically, our users are entering their address instead of using their GPS location. I am not using the location because some of the mobile devices are sending wild coordinates that are off by many hundreds of meters.
The data includes a standard photo which we use to count insects on a window within a defined area. We do not expect our users to do the counting so we do it for them but would want to add our count along with the known coordinates of their address after we receive their entry.
Has anyone done anything like this before? If so, can you advise me how you did it?
The project is called MIDGE WINDOW SURVEY
