We measure the grid at inverters, which tells us the suburb and not the street. One tap from where you are standing tells us which part of Constantia this is.
If you allow it, your phone’s location tells us the street. We keep the pin and your answer — no name, no contact, nothing else. Declining still counts your answer.
GridMapper measures the grid at inverters every few minutes. This page is one event in Constantia. See the suburb's record.
