Let me conclude with a little anecdote that shows the sort of thing we must
deal with. A farm near where I live was visited by the supervisory
authority, because the satellite system had allegedly enabled it to identify
a gully, in other words a prohibited drainage system. The inspectors said it
must be over there in a particular spot where the system had shown it to be.
The farmer, however, assured them that he had done nothing. And what had
actually happened? A plastic mat was lying in the field – which should not happen
either – and the grass had grown through it. That was what the satellite system
had picked up, and now the authorities had come to haul the farmer over the coals.
