Confidence Levels
AfriGIS confidence levels are an indication of the level of accuracy to which an address has been located. Confidence level 1 is an indication that, for instance, the address is accurate enough for someone to locate your front door/gate. Confidence level 4 means someone will be in your street, within 5 meters of your location. If the closest point of confidence is the centre of the suburb, the address will be assigned a confidence level of 6.
